McKinnon 283 vs Chevy 283

[oldguy_46ca]

A member of my chapter claims that Studebaker engineers made changes to the McKinnon supplied V8's they put in '65 and '66 cars that improved them over the Chevrolet version. I say they were identical and no changes were made to the engine. What say you?

A 283 is a 283.

I can't believe this is still being debated after 50 years.

After reading way more than I needed to answer my simple question, much of which I already knew, I take it there was no difference at all in the engines.

I didn't debate the guy. He is someone who should know better and I am relatively new to the club. I just wanted confirmation that what I am certain of is true. The sad thing is we were at a carshow today and he was representing that there were significant differences to passers by.

I just meant "in general". After all these years, I'm surprised people still want to think otherwise. Good on you for trying to get the right info out there!

Goes to show that some will believe whatever they want to believe... no matter what!!! No time limit on such silliness, either.

My understanding is that the 283 Mckinnon was a GMC truck motor. I believe the only thing Studebaker did to it was install the carburetor and the valve cover stickers.

[StudeRich]

Actually they did not even do that, unlike the Avanti II's they did not omit or trash the Rochester Carb. they left it on there!

So that leaves the Checker and Jeep Bellhousing, Borg Warner Trans., Prestolite Alternator and Valve Cover Decals to add.

A 283 chev is a 283 chev weather you put it in a studebaker or a ford.

[Commander Eddie]

I am sure at that time, Studebaker did not have the resources to spend trying to tweak a perfectly good engine. Just drop it in and go.

sounds like a discussion along the lines of: yea, the Troybuilt & Deere units you can buy @ Lowe's or Home Depot are better than the ones made for a franchise dealer....

Absolutely correct. The same 195 HP 283 installed in Studebakers was also installed in GMC trucks...and Chevy trucks, and Impalas, and Chevells, and Chevy II's, and marine applications, and Canadian Pontiacs, and others. Part for part there is NO difference between one 65-66 195 HP 283 and another.

So, if you want to say that Studebaker used the same motor that was used in GMC trucks, you would be correct.

USA market GMCs did not use the 283 in 65 or 66. They were still using their exclusive line of V6 engines... though they did also offer models with 230/250 and 292 Chevy inline 6s starting in 64. http://www.6066gmcguy.com/Inline6.html
Sorry for straying off course...

Good point. I guess you'd have to say "Studebaker used the same 283 that was used in CHEVY trucks."
