  1. Okay, whoa. Wait a second. I haven't gotten into the deep tear down on my car, but you mean to say there are 5 on 4.75" rotors on Blake Avantis, and then an adapter mounted on top to revert to the 5 on 4.5" pattern?

    I'm converting to 5 on 4.75" when I switch to C4 'Vette suspension, but next spring I'll find the tear down a little more interesting.

    Now to bring relevance from mfg's original post: If anyone wants 1985 front rotors, I will have two takeoffs I will not need.

  2. I'll definitely be documenting my progress with my basket case, both in stills and in videos. There is so much I want to do to it, and don't mind at all making my alterations publicly available. I have reached out to the owner of the Targa Tasmania car, to learn more about it. As you say, it would be great to see more shots of the frame and body together.

  3. So I should have clarified in the beginning: I know I'm not just applying a filler between the body and frame. It somewhat is, though I know said filler needs to be of a certain conformity. I'm also aware the roll bar attaches to the torque boxes. I am also contemplating replacing the factory stamped steel bar with DOM steel, like an actual roll bar.

    This has already been done, and the car to feature it sustains road course beatings. I'll picture it here, but this pic. and more are linked in the initial post. I'll stop posting links inside of my written text. Maybe that hid too many details?

    Carbon fiber is strong, as this segment shows, https://www.youtube.com/watch?v=hjErH4_1fks. Also, I read about Chevrolet sandwiching balsa wood between composite materials. That made the floor 10× stronger than using composites alone, plus balsa filters out noise and vibration.

    Okay, so culminating all of the above: I am taking aim at creating a rustproof substitute for stock torque boxes. I may use chopped mat fiberglass, I may use carbon fiber, I may include balsa wood, I may pick everything listed above, and some materials unlisted. I just want to recreate "structural fiberglass sills in place of hog troughs" as seen below.

    Now that it's better explained, and better visualized, how do you suppose this was done?

    and has done away with torque boxes. That car's frame has also been 'sturdied' as seen in one picture.

    Normally what, the frame bolts to the torque boxes and the torque boxes are adhered to the body, yes? If the torque boxes are omitted, the frame must bolt to something. The quest then becomes to create that something. What hits me right off the bat is, I would borrow a page out of the C5 & C6 'Vette book, sandwiching balsa wood between two fiber mediums. Or just sandwich three to five fiber mediums together, oriented in different directions. The final creation also needs threaded inserts or similar solution, to anchor the bolts.

    My basket case needs some underside work and I too may omit torque boxes.

  5. I am interested in all of the internal specifications. As in, fill out a blank cam card with RS1021 information. Also noteworthy, what are the valve spring details? With today's tech., could we do with 2 springs what was originally done with 3 springs?

    My angle? I'd like to build up a reproduction of RS1021 that doesn't guilt me about adding miles. Had we known much sooner the history of 25, it wouldn't have been driven. My vision during the middle '90s was, once the car rolled to 100k miles, tear it down and restore it. I felt the zeroing of the odometer was a good pause point.

    My current project is due to my love of lateral-g vehicles, I'm working an '85 into a modernized homage of the Avanti GT. A manually shifted and modernized version of 25 would be a cool juxtaposition to that build.

    I would like to solve the mystery involving this part. My name is Mike Phillips, and I am the creator of the spoiler / air dam in these pictures. In the 80's I owned an auto body shop and was a member of AOA, during that time I owned a '63 R1 and a '70 Avanti II. I designed and executed both the positive (plug) and negative mold to produce these parts which I still have. I would be glad to answer any further questions anyone may have.

    I have a guesstimate about the process. Am I a couple houses away, or at least in the right neighborhood?

    The gist of how much I understand goes like this
    1) Slather PVA on the + and -
    2) Allow that to get tacky
    3) Lay in material (fiberglass / carbon kevlar / carbon fiber)
    4) Add resin with hardener
    5) Roll out air bubbles
    6) Repeat 3-5 a couple more times
    7) Clamp the positive and the negative together and wait.
    7 alt) I've also heard to make a large vacuum sealed bag, put the creation in there and suck all the air out. And wait.

  7. I recall draining the Paxton with my dad in a former Avanti we had. We used an air compressor and a sprayer nozzle, one of the nozzles which also has a suction opening beneath. Attach a vinyl tube to the suction side that fits into the blower's dipstick tube, and put the tube into the blower oil.

    Get a bucket and a rag. Put your hand and the sprayer nozzle partway in the bucket and cover the opening with the rag. Spray away.

  8. I'm prior owner's son. I drove 1025 to high school (and regularly summer '95- spring '97), and then a little bit to college in the SF Bay Area before I wrecked it on a Livermore back road fall '97. It experienced quite a few "down days" as it didn't make for a reliable daily driver, but while it was up, it was tons of fun! Dad in East Bay, Mom in South Bay. Dad would have me pick up my younger brother "every other weekend" in it. 580 to 680 to 280 was a fun commute with or without rush hour traffic.

    Anyway, the thinking at the time it was developed was, longer stroke did give a low end power bump. Vince and Andy had said 1025 was the quickest accelerating Avanti they had, that's why they loaned that particular car to magazine testers. Also, think of it this way: they'd already achieved 299 cubic inches via an increase in bore, so if you're aiming for different results than the +0.060 cars, the only remaining alteration is an increase in stroke. There's a third way to make a Studebaker V8 299 cubic inches, and it's an exactly square bore and stroke of 3 5/8 inches.

  9. I can tell you how I discovered what it would have to be. I created a spreadsheet that has the constant (pi \ 4) and the equation for displacement. I entered the number of cylinders, the Studebaker bore of 3.5625", and the spreadsheet spit out 3.74957" as the necessary stroke to give an even 299 cu. in. V8. From there it was a pretty easy decipher that 3.75" would fit.

    I also found in reading articles online that the Paxton crew had stroked Studebaker engines out to 4" plus; I even think I read a page where one was punched to 4.25" of stroke (that'd make a nice Champ engine). After I read that (I wish I took a screenshot or bookmarked the site), it cemented in my mind that the Santa Monica guys could have easily stroked RS1021's crank.

  10. The SDC aero thread is rooted in 2012 and this one got its origins in 2006. I don't know why year would be an issue, if it is relevant information all being compiled into the appropriate thread for reference.

    A 2019 Ram is .356 because all major manufacturers in recent days have aimed for lighter weight and less resistance to achieve better MPG numbers. Studebakers of the 1950s and 1960s achieving 0.31 or 0.37 or even 0.44 are incredible feats, especially since Raymond Loewy told Porsche's chief engineer that he designed the Avanti by feel and intuition.

    Who in the Studebaker and Avanti clubs lives in or around North Carolina? There is a wind tunnel (A2) and it is open for rented sessions https://a2wt.com/

    If nobody has jumped at the opportunity by next fall, I am considering taking my '85 there to find what it is. I'd still love to see a factory Studebaker version get some figures too though.

  11. Ron Rifkin posted to the Avanti Owners Association Facebook page, with an attached image of the book Industrial Design Raymond Loewy.

    "I remember when the chief engineer of Porsche in Stuttgart asked me, 'Loewy, how did you wind-test the Avanti?' I said 'Why do you ask?' 'Well, we know a little here about streamlining and your Avanti is almost perfect, no parasitic noise at high speed, skin friction reduced to practically nothing.' I said, 'I didn't test it at all.' He couldn't believe it. 'No', I said, 'I did it by feel and design intuition.'"
    -- R.L. in a 1978 interview, in this excellent book.
     
    So there's a solid answer about Loewy. By his own admission he went by feel and design intuition. I would argue a little though that he was aware of tried and true aerodynamic cues, which had been implemented on cars meant for speed.
  12. Yeah, I like the blended bumper Blake cars, and have missed opportunities over the last ten years. Finally something came up when I had the funds available.

    I grabbed a frame out of a storage place in Utica. The owner had to clean out everything because they had to move out. It's just a stock '63 frame. In fact somewhere I have that Avanti's VIN stamp written down.

  13. Yep. I had bigger visions, though it would have taken a little longer which would have been fine because I was willing to put more time and effort into it.

    YouTube THE DRIVE channel and Mike Musto's show "Big Muscle," and TheSmokingTire channel with Matt Farah's show "One Take." Get a larger audience. Put everything out there.

  14. I recently grabbed an '85 with a shoddy underside (a lot is gone) and bought a new frame. I will be treating the replacement frame with something to ward off anything that eats metal. My main (Maine- ha ha) defense is, I won't be driving the car after Thanksgiving and before Tax Day. My second line of defense will be something like a POR-15/rust doctor application. My third line of defense is, I plan on running a belly pan on my car, at least aft of the firewall. That will cover the x-brace and the torque boxes with something like sheet aluminum.

    I concur to those remarks that plain water isn't the real baddie here. Soap and water aren't bad things for metal as long as drying is a step not skipped.

  15. I grabbed the white one (VIN ending 4174) advertised on Facebook, at the end of August. She's an absolute 100% basket case but I am completely okay with that. I have many resto-mod plans. In September I bought a replacement frame, however I still need torque boxes.

    Step 1 for me is: Treat it like a race car and gut her. The sunroof leaked, so much, but not all of the interior is trash quality.

    Step 2 is next Spring: The engine, transmission, driveshaft, front suspension from wheels to control arms, and rear suspension from wheels through the differential will come up for sale.

    I have the arm rest off, but how do the rest of the door panel items remove? The door handle, power door lock switch, and remote mirror controls are conspiring to give me an aneurysm.

  16. I picked up the white 1985 out of Ohio as a whole car and my intentions are to revive her via a resto-mod; she's been sitting for over 2 decades. I should reach parts acquisition mode over this winter and then I'll start installing said parts after the snow melts next spring.

    First thing first though, and I'll do this before cold weather comes: rip out the old dead parts. I'll clean what I can, sell off or give away what I won't use on the flip side, and keep what I need. I know I need a frame. I've seen them priced right at $1k, but that was before the Bidenflation circus came to town.

  17. I could have sworn there were (200) 1984 and (100) 1985. At least the former avantisource.com site had those as their numbers. I spent a day in July 2013 screen saving a lot on that website. 1983 had an easy number to remember, (289) produced.

  18. So to give a Blake appearance to an earlier car would take cutting of the existing body, the newer SMC pieces, and some fiberglass jig / bonding work? I trust there is a hard steel bumper beneath the SMC cover.

    I found an '84 in a junkyard, good for what I'd like but the seller wants 4500 and states the frame is rusty. I'd need him to come down in price to make that worthwhile because it may require a better frame. There are couple other Avantis scattered around the country, an '80 for less than the '84. And that's what inspired this question.

  19. Hi Ed. I'm well. 1025 is needing some minor engine bay work with the distributor, and then some suspension alignment detailing to be road worthy. My dad and I want to get those done and some test miles back on her. Maybe I'll borrow her from southern Maine and drive her around my home area for a bit? We would love to make that meet in Vermont with her come August. There's more I will amend in my Composite bumpers thread.

  20. I have a question regarding the differences between the early chrome bumper cars and the later blended bumper. What are the physical differences, not only in appearance but to include mounting points or changes made underneath the skin.

    I have a keen attraction to the Mid-Ohio GT car and seek to pay homage to it in a build. I could get one of the (300) 1984 & 1985s, or I could expand my search and give an earlier one composite bumpers.

    I guess that's a related question: Which way is more economical? Picking up a Newman / Altman II and updating its looks, or initially buying a Blake car?

  21. Ed, you seem to be one who stumbles across these screamin' deals. I am looking for a blended bumper Blake car as either:
    1) An inexpensive fixer, exactly like this announcement back in December.
    2) Only a fiberglass shell. I can build one from the ground up.
