So, Autolite Platinum AP85 plugs would be appropriate for both an R1 and an R3??? I ask because I have both an R1 and an R3 which both need new plugs. Thanks in advance. --Dwight

These are what I'll use on my R3. Thanks for the recommendation. --Dwight

Unfortunately, these are on "National back order."

IIRC Champion J12Y plugs were specified by Studebaker for both R1s and R2s. The modern number might be RJ12YC. H14Y plugs were spec'd for 259 & 289 engines J10Y plugs were used on R3s (J10Y are colder than J12Y) This is IIRC, so someone correct me. --Dwight P.S., Autolite 437 & Bosch 7517 have also been recommended previously on the SDC Forum

Thanks for sharing. This might be something that one of our larger Studebaker parts suppliers could manufacture. --Dwight

Below is a close-up of the pic in the post above and lightened. It appears that the builder of the black '63 Avanti didn't want to drill any new holes either, so made a bracket to hold the 51R battery down. Look closely. --Dwight

Normally, you should have TWO keys, one for the ignition & doors, and another for the console & glove box. That's how Studebaker did it, and your car is a '70, so should be the same. Many times the ignition switch fails and is replaced. That's how a car becomes a three-key car. The door panels can be removed easily. Perhaps a locksmith can reset the door lock cylinders to match the ign key. Or, at least, he can make a key for the door locks. May have to look online these days for locksmith services. --Dwight

Are you selling or buying?

Good! After the discussion a year or so ago on fluids to use in blowers I concluded, for me, to use B&M Trick Shift, the blue non-synthetic ATF. It meets Type F ATF standards. --Dwight

After a certain serial number '63 Avantis switched from a 3-pole starter to a 4-pole one. What is your serial number? The 4-pole starter was added by Studebaker to address the higher starting power needed by the 10.24 CR of the R1 engine. I don't know whether parts will interchange between them or not. --Dwight

Of course you didn't get all of the black stuff out of your superchargers when you sucked the old fluid out. What you might do now to get essentially all of it out is to change the fluid again very soon. There has been some lively discussion on what fluid to use in superchargers within the last year or so on either this forum or the SDC Forum. --Dwight

This is what I get:

I can't get onto the SDC forum, and haven't been able to all day. What comes up looks like the normal logon page, minus the graphics. And, it won't let me log on. What do y'all know? Thanks for any help. --Dwight

Let's use very quiet mufflers on all the engines so that we can single out the engine noises. Then, one engine noise to consider is the sound of the pistons swapping holes in the R3 & R4 engines. By that I mean the piston slap that one can hear with "quiet"mufflers and a nearby building to reflect the sound back to the driver when driving relatively slowly. Under WOT that piston slap would be in the mix of all the other engine noises. Also, aren't the valve clearances greater for R3 & R4 than for R1 & R2? If so, then the R3 & R4 would have a bit more lifter clatter. I'm not trying to provide the answer here; just adding up some of the component noises. BTW, ALL Studebaker engines (excepting the 56J) have solid lifters. --Dwight

A couple thoughts: 1) The exhaust sound of a Studebaker V8 is much louder than that of a Chevrolet V8, all else being equal. 2) The exhaust sound of an R3 is notably different than that of an R2. 3) Wouldn't the R4, with its two carbs, make a loud sucking sound when under full throttle? (I haven't had an R4, so no experience here.) 4) The supercharger of an R2 or R3 will make a nice scream when under full throttle. 5) The more horsepower an engine produces the louder its exhaust. So, it depends on what kind of exhaust sound one wants. --Dwight

I notice a couple things: 1) "Engine number: S-2514" Normally Avantis' engine numbers started with "R", so your engine number should be RS2514. 2) "One quart P6335". P6335 is the code for Avanti Gray paint. That is acrylic lacquer. --Dwight

AFAIK NOS Strato Vue mirrors haven't been available for decades. The current reproductions are superior to the originals. So, the issue is the screw spacing of the repros, isn't it? --Dwight

I recently bought a group 51 battery for a '63 Avanti, but now wonder if I should have gotten a 51R (same except terminals reversed). I need to decide while I still have time to exchange it. The 51/51R battery is smaller and much lighter, is of modern technology, costs less, and lasts longer. What's not to like about a 51/51R (unless you're dedicated to originality)? The pic below shows a 51R installed in a '63 Avanti. Everything on this car looks well done, so I figure he knew what he is doing. He has re-positioned both hold-down posts and has made a bracket to move the fender-side post forward. It looks like these changes have made using a 51R battery a better choice than a 51, although it looks like either could be used. The 3EE battery is (LxWxH, inches) 19.3125 x 4.375 x 8.875 The 51/51R battery is ........................9.374 x 5.0624 x 8.8125 The 51/51R is ~0.7" wider -- should be no problem The 51/51R is ~ 0.75" lower in height -- no problem Comments? --Dwight
