Well do you have headers? Full exhaust to me means yes.

Just curious as to the average pulley size people tend to run with a top swap and headers.

i ran a 3.4 right away on my cammed top swap. never knocked ever.

No I don't have headers. The average I think is 3.8.

Headers I take it? Regardless, that would be an insane boost from the GT.

yes. i had headers. the only time it knocked was after i spun the bearing. then it knocked when it was idling. haha.

My friend has his stock s/c still cuz he used a turbo, I wonder if I should put the s/c on the GT...
