Took this photo of my uncles old GMC rusting away in the autumn scenery ten years ago today. Made a good jigsaw.

Yes they were a better engine than the 235 Chevy was, that 270 and 301 were as tough as they come!

I don't know if our Canadian GMCs had anything other than a Chevy engine. It quite possible but I wouldn't know the difference. I know my brother has a 47 that was converted to a later model engine. I think a 261 possibly.

GM made the GMC and Chevy trucks very similar. One thing I remember as a teen, and don't remember if both had it done or just one of the pair, was that taking the 270 and splitting the exhaust manifold for dual exhausts with Glass Packed mufflers had a sound of its own.

I had a 47 Chebby, small block, no add ons, 3 on the tree as my first truck. I bought it well used after the summer of 1959 (vacation earnings decking on a tug boat) and my first task was to change the black oil. That was a mistake as it smoked like crazy...apparently the used car dealer covered up that fact prior to the sale....90 wt oil in the crankcase?

I think that split exhaust manifold might have been a GM factory option for their trucks. I've heard the sound of them on yt videos and did not care much for it. Nothing like a V8.

Agree on the V8 performance preference.....something to beat, a 1955 265 Chebby small block V8, 3 on the tree, dual exhausts,
Smitty Glass packs winding out in 2nd gear......sweetttttttttt....for the lucky guys that had one at the time (girl magnet)....which I
didn't, just lusted in my heart (Jimmy Carter) for the car and the girls.

The Fenton split manifold was the "Thing" for the Chevy guys back in the 50s.
The 6 cyl. Chevys with the Fenton headers had a unique and great sound. The Ford flathead V-8s also had a unique sound different than the OHV V-8s due to the center two ports on each side dumping into one manifold port.
A good friend of mine bought a brand new '60 Chevy hardtop with a 6 cyl. and three on the tree. That seemed like a really wierd combination but he put a Fenton dual header on it with "Smitty" glasspacks and it sounded "mean". It sure wasn't any "ball of fire" though. LOL

Pretty sure the split exhaust manifold I have here is an original GM product although I know Fenton made a lot of performance parts for various engines. I'd like to have duals and glass packs on my 52 Merc flathead but for now am satisfied with a single straight pipe. For me there is just no substitute for the sound of a V8.
