Ford could have at least come up with a name other than Mustang for that “car”???

mfg is referring to the Mustang Mach-E. And yes, it's a disgrace to the nameplate. Some people bring up the Mitsubishi Eclipse, when discussing the Mach-E, as the Eclipse too went the way of the crossover body style. Mach-E, yuck!!

A Studebaker—Packard—Hudson—Nash merger certainly would have have been interesting!

IIRC, when I c.c.'d a pair of 1557570 heads 58 c.c.'s seem correct. I am not sure where the 54 c.c. figure comes from.

Nothing good!….Ask any Ford dealer!!!!!

Once again, thank you for those quick responses. Glad to clear that up.

What exactly happened to the poor Ford Mustang?

Nailed it..there's very little that could escape your Avanti knowledge......

Ron, really nice workmanship. What thickness panels did you select, and if you had it to do over again, would you change any procedure or materials?

After what happened to the poor Ford Mustang, do we really want to see a battery powered Avanti??

The (I believe) four Packard Panther sports cars created in the early fifties looked a bit strange…. However, the Packard Predictor show car of 1956 really looked outstanding! It’s worth a trip to the SNM just to see that car!

The intake valves are larger than the exhaust valves. (You have them reversed.) --Dwight

Hello all, FYI I checked my 1557570 heads that are fresh from the machine shop and they are 58 cc's. These heads have been milled .004" to clean them up. John C.

The only difference between those heads is indeed combustion chamber volume.

Question regarding heads for Avanti's or any Studebaker. I've reviewed the info on Head castings from Bob Johnstone's website and what I gather is the key difference in head castings for R1 (1557570) vs an R2 (1557582) vs lets say Golden Hawk (535976) or (1555294) appear to be the combustion chamber volume. Somewhere in the review was the comment that valve sizes were all the same regardless of head casting, with Intakes at 1" 17/32 and Exhaust 1" 21/32. My question is this. Is there any difference in intake & exhaust runner sizes/volumes? Are they all the same? Is it then true the only difference is combustion chamber volume? Are there any differences other than combustion chamber volume?

There's a brief discussion on the wheels on the SDC forum: https://forum.studebakerdriversclub.com/forum/your-studebaker-forum/general-studebaker-specific-discussion/29343-halibrands-dealer-option/page2?28618-Halibrands-Dealer-Option=&highlight=halibrand

YOU are the Documentation KING Regnalbob! 🧐

AMC sold the Alliance, Encore, Fuego and Sport Wagons thru Jeep dealers.

I get originality.. it’s important to identify what’s correct and what isn’t… Having said that, it’s sure hard to beat the ‘look’ of Dayton wire wheels on a Studebaker Gran Turismo Hawk!!

They are the second type.

Dwight. That’s about how I feel. I see the 64 type on 63 Studes and they just don’t look right. The 63 type are really different than the 64. I like them both but once I knew the correct application then each has its proper spot so to speak.

Beautiful Super Hawk!…. If the set of Halibrand wheels on your ‘64 Daytona HRM car are the “second” type… I think I prefer the look of those to the look of the “ first “ style Halibrands on your ‘63 Hawk.

Preference is only part of the equation. If I had a '63 Daytona HT (as I would like to have) I would put the '63-style mag wheels on it. And, I would buy a set. --Dwight

If what you refer to as the '64 Halibrand wheel is the style currently available in reproduction, I prefer it to the "Kidney Bean" Halibrand wheels shown on the Hawk.

I’m not sure how many Avanti owners realize that a different Halibrand style wheel was originally offered for the 63 model run. These wheels appeared on the 63 Super Lark at the NY auto show and probably the other major auto shows. They are also on the 63 R2 Super Hawk road test in, I believe, Motor Trend magazine. How many would be interested in a set of these in reproduction form?? The wheels are shown here on my “survivor” R2 Super Hawk at the Studebaker National Museum. By the way, this Hawk is 100% original including the super red paint. Super red was only available “if” you ordered the high performance package so it s very rare. This particular GT Hawk is probably the best totally original of its kind in existence.
