Dad where are you ending the 350? I'll admit my knowledge of the later motors is a bit thin, but wasn't it basically the same motor into the 90's?

My '85 L98 has cast iron heads. Starting sometime in '86 'vettes got the alloy heads and about the same time the one piece crank seal. My '91 K2500 has a 350 that aside from the TBI looks like a basic cast iron 350. Isn't it still the same motor? And didn't they use it in pickups a few years more?

I absolutely agree with your conclusion, the 350 was made longer than any of the other small block Chevys, and the small block Chevy has likely been installed in more cars over more years than any other American made motor.

More challenging to build and modify is the GMC inline. Parts, especially hot rod parts, are harder to come by and more expensive when you do find them.

The guy who bought the rights to the Wayne head apparently could not make it financially even though he was simply reproducing an old design. I'd love to have a jimmy with a crossflow head but it is unlikely I'd spend $5,000 to get there...

It's true. I really don't do anything but browse the Internet looking for trouble...
