Over the years Ford always had a "better Idea" at least as far engines go.But back in 55 Chevy had the 'Best" idea and they are still using the same basic block design.
At one time Smokey Yunick expiremented with every engine from every manufacturer and he alway went back to the sb Chevy. I may be wrong but I think he said it was the best damn engine ever made.
If I wasn't a hard headed Ford guy I would have a Chevy in my Fake Cobra.
