Which Stock Cast Iron 2bbl Intake is best?? I've heard about a "313" but can't find a refrence for it?????? I run a Street Stock Camaro 4412 HolleyThanks
the best that we have found is off a bus or hevy duty truck without the EGR port they are a little hard to find but can be done and the motors also came out with the big ram horns
what about the GM mercruiser 2 brrl cast iron vortec intake on vortec heads ????
Try and find one that doesn't have an EGR passage. You need a junk yard prior to 1965....Bob
