Not sure but everyone says they look too small even without measuring and theres a big gap between the middle pipes and on my Hookers theyre almost hugging.
Well after a conservative tune up, 34* timing, and not even playing with the 750HP carb(only one we could use) and a 2" spacer.. it made 496hp @ 6500 rpm and 462 ft/lbs of TQ at 5000 rpm. It mirrors the pulls very good, one after the other it put the same #'s down. We feel it has more to gain with manifold porting(already started) and a bigger carb. Hoping for 525 with the manifold though!
