i have a 1999 trans am with slp cat back and a k&n cold air intake. im going to put headers and high flow cats on before i put the heads and cam in. im looking at the vrx5 cam by vegeance racing. i was was wondering if anyone has used this cam and if they liked it. i dont mind a choppy cam at all.i also want to do heads but wandering if i can get away with port and polishing the factory heads and replacing the valve springs and necessary parts to handle the cam. im going to be driving this car like a mild daily driver.

It is a bit too much overlap for cats. Look at something different or ditch the cats.

what would u recommend with the high flow cats.

The VRX4 on a 113 LSA, 3* OVERLAP, send your stock heads to AI and you'll be pleased.

I dont understand why it effect the cats? Can you explain please? With a set of 100cpi cats, surely there is enough flow
