Stock cars knock even with the stock 3.8 pulley so why would you risk chipping a piston by throwing on a smaller pulley..

Cuz racekar

i ran my rockered header 3.4 setup on a stock tune for a while

[camopaint0707]

yes, i wanna see if explode

[dsmuts]

Stock the tune runs rich enough to run a 3.4 setup and probably even more. On the 3.4 setup I had on stock tune i was at 10.8ish afr.

I'll be a guinea pig for it. Stock my car had essentially 0KR except at WOT shifts. Now with headers, colder plugs and soon a CAI, I will put a 3.6 on (after scanning). Don't plan on getting a tune either.

[dsmuts]

It'll be fine Matt

I have headers, cam, stock tune, 3.4" and I still see knock. I feel there's crap causing my knock though, like vacuum leak or something. Just can't seem to track down my problem >.<
