will J heads work on a 318? And many many more questions.

Either is fine...I kinda like the stealth...does it have a little bit more top rpm???

P.S. Just checked..Weiand dual plane Stealth intake manifolds feature long, separated runners for bottom-end and mid-range power, plus a special runner design and larger plenum to flow the air needed for high-rpm horsepower. They mount single, square-mount 4-barrels and make power from idle all the way to 6,000 rpm. That makes Stealth manifolds the perfect choice for your street/strip vehicle.



the performer is done at 5500...the stealth pulls higher
