Mach 1: yep, checked into it, and it does have the exhaust crossover passage necessary for EGR....therefore, I *assume* it would be cool, emissions-wise... Oh well..... I guess for now, I'll just leave it to the ol' pocketbook to decide, hehehe.
I'm going to keep diggin' for flow numbers, and I'm sure some of the mags out there already have or will have an article on each of the available 351W manifolds. I'm not going to even bother calling the individual companies for numbers because they're all going to tell me the same thing: ours flows the best!
