YBLOCKMERC (1/16/2014)
You've gotten some pretty friendly answers here, from guys who really want to say..."#%@&!% What are you thinking!!" The Y is a very satisfying engine and properly built, makes a '56 a great show and go machine. Get a -B intake, 4V carb, '57-up distributor, dual exhausts and a C4 tranny and you're good to go. There is a lot of knowledge and assistance here to help you sort out any issues you may be having; listen to them. Well said, Marc! I'm going to submit your name for 'Diplomat of the Year', too!
IMO, while ‘old’, the Ford y-block is structurally a sound engine design. In 1957, the flaw to its continuance in production was not having planned for sufficient cubic inch increase in the block casting.
Looking back, the original ’54–’64 FoMoCo cylinder heads imposed a definite rpm and horsepower limitations, also. These limitations have been ELIMINATED by John and Geoff Mummerts’ design, production, and assembly of quality aluminum cylinder heads in the last two (?) years. Bolting a set of out-of-the-box Mummert heads on a previously warmed over 312 has proven to yield 50 horsepower and dramatically increase rpm capability!
With Mummert cylinder heads and the implementation of rudimentary carburetor, ignition, piston, and camshaft improvements developed in the last fifty years, the y-block has the performance capability and SOLID reliability for any street or competition application.
Members of this Forum have built carbureted, fuel injected,supercharged, and turbo charged engines that outperform more storied engines of equal and larger displacement.
Though out of production in the U.S. for 50 years, the FoMoCo y-block engine has amazing horsepower and torque potential. It will amaze you, anyone that you take for a ride, and anyone you draw for a competitor should you go in that direction.
I don’t know your fabricating experience or capability. Executing and sorting out an engine swap can be a lot of work.
Build a y-block, it’s a sleeper!
