Inliners International Forums General Discussion Blown and Injected Hacking together EFI on an Pontiac OHC Six

Hank, your comparing his ports to a siamese head that are way too small for those Chevy engines. A 250 has the same cylinder volume per cylinder as a 350 SBC does. And these OHC engines were designed for HP in mind, while the 250 Chevy was not. I bet if he was to cc an intake runner, it would still be smaller than an average stock SBC runner.
