I recently bought a 2002 Z28. When I bought it, it had a Borla cat-back, SLP lid, SLP ram air, K&N, and smooth bellows. I just ordered Dynatech long tube coated headers with high-flow-cats. Next on my list is a Predator programmer. In the next couple years I'd like to put a Procharger on it, but am looking for some cheaper power in the mean time. I like the idea of a cam, but don't want to really tear into a low mileage motor and possibly cause leaks, etc. I've heard some good things about 1.85 roller rockers on bolt-on cars, and would like to get a set, but am wondering if these would work well when I put the charger on it in the future or if they would have some sort of adverse affects. Also, are the stock springs ok with 1.85 roller rockers?

Any input would be appreciated.

Thanks

 

stock springs are not sufficient to handle the 1.85s....they are only good to .525" and the bigger rockers will put you up to nearly .550" lift with stock cam.

i would think the increased breathing would greatly help the SC.
