"* On Pontiac engine sizes, others have been overlooked; namely the ‘58 370 (4.06” bore and 3.625” stroke) with a forged crank and overbore capability. This engine could be a real animal. Also, like it or not the 301 -265 is a Real Pontiac. How could you say otherwise, because the deck is shorter and it has siamese ports? Well, the 50’s Pontiac had siamese ports too, just on the exhaust side. They use the same tooling and the same dimensions for the most part- distributor, ign system, valve covers, t-cover, oil, water and fuel pumps, motor mounts, bell housing pattern, head bolt pattern (even an Ram Air V and M/T HEMI head fits) camshaft, the Pontiac engineers did a good job keeping the design alive during trying times in the US auto industry. I wish the turbo set up would have been more successful, it would have benefited us all and maybe kept the motor in production. It could be brought back but, I don‘t see that happening. They are production engines, not performance engines but, still Pontiacs. Finally, the GMC trucks that used Pontiac V-8s in the 50’s. Many had a small bore version of the car Pontiac engine for the given year. I think the ‘57 version was a 336. Who else knows about this? Few do. What other sizes were there. That is also a trivia question on my web site."
Overall an informative post. I learned about the
336 Pontiac GMC engine. Tom V.
