Reply to "Recommendations on intake manifold for A3 heads and shop that can bung it for EFI"

Looftie, be aware that the Ford C3 head is NOT a 'slightly modified' C302-B head. It is in fact a completely different casting made for later NASCAR use. Among the significant differences are very small combustion chambers requiring new pistons or otherwise figuring out how to live with 14+:1 compression, shaft-mounted rocker arms such as Jesel in place of stock 351-C stud mounted valvetrains. I was told that no production intake manifold bolts on- they all need machining to fit- by one guy that, after thousands of $$$ spent, finally got his C3-head Cleveland running in his Pantera. He used D. Quella's split Weber intake with TWM/Weber-lookalike IR EFI setup. The injector bosses are already in those paired intakes. They require a custom built valley cover, too.

Using such heads really requires a complete engine built around the specifics of C3 heads, which is why C3s are often cheaper than other Ford Racing aluminum stagger-valve heads. I would steer clear of them except for a purpose-built pro-race engine by a shop that's been there with C3 builds. I would NOT try doing it yourself. Good luck- J DeRyke
