Default Re: Replace Flathead with Y-Block?

The 312 wasn't any better. It was the worst of the bunch. The 292 was lousy but probably the best Y block. The 57 312 introduced the Holley spread bore carburetor which was a milestone but a terrible overall engine. The engine code was ECZ. I know, I had several back in the day.
