Hybred head for flat head Mopar - 11/17/08 01:18 PM
Since circumstances prevent me actually working on my project I’m doing it “mentally’ instead. I’ve been investigating chopping up a newer overhead valve head for use on the Mopar flathead. The problem I am running into is that all the heads I have looked at place the push rods too far away from the centerline of the bore to be compatible with the old Mopar which depending on type, only had a bore of 3 inches or so. Since most modern engines are about an inch bigger, the spot where the pushrods come up is too far out. The heads I have looked into were all Mopar because I have drawings to look at. Has anyone investigated this? Is the small block Chevy or Ford more compact? It looks to me like the magic number would be around 2 5/8 inches from centerline of bore to centerline of pushrods.
