Gmc v8
 

What years was a V8 available in GMC trucks and what Cu In?

Re: Gmc v8
 

I don't know if it's entirely true, but supposedly they had a GMC‑designed V8 from 66 to 72 that was 637 cu in -10.4 liters.
Holy cow.

Why does AI say a 283 was an option?....and wikipedia?

Re: Gmc v8
 

because of the Canadian versions of GMC trucks of the era-- the 910, 920, & 930 series were all chevy powered.

That's definitely true, Fetch. The 637 V8 had the same bore and stroke as the 478 V6. It was a replacement for the 702 V12. Almost the same power, but much shorter and lighter in weight.

Hi Lewis, so what Chevy motors were available? 283? Are you saying no V6 in Canada 60-66?
If they had a Chevy V8, what about the V6 hood emblem?

What about the law suit in 1959 against GMC for using Pontiac V8 with a GMC sticker? Using Chevy motors is the same false advertising issue?

Anyway the question still remains. Were there any USA GMC's with factory option for a 283 V8 in 60-66? AI and Wiki say yes but I have learned NOT to trust those resources. I trust 6066GMCCLUB only.
