s13 sr camshaft inquiry

[ivantheterribl3]

I recently picked up a long block from a local engine importer for the purpose of replacing the stock one in my car. The old one had more blow by than I was comfortable with and this new one had top feed 550s, nismo fpr, and metal head gasket. The guys at the shop told me it had cams in it. I just got it on a stand and opened it yeterday to find tomei 256x11.56 (iirc) intake and 260x12.something exhaust, and a set of tomei adjustable cam gears. The exhaust was zeroed and the intake was advanced 2 notches I believe. Might have been retarded I cant recall. It also had a set of heat range 6 ngk plugs in it which I thought was a bit odd. My question is can anyone point me towards a good thorough cam tuning guide online or in print? The motor will have an off the shelf garrett gt2560 bolted to it which im hoping to max out around 350 with a relatively conservative tune. Any insight would be greatly appreciated. Btw car is mainly drift duty so im not looking for super smooth idle or comfortable driveability. Thanks yall

Sorry? You're asking for a tuning guide for the camshafts?

I could help you with some consulting on the tuning if you need it.
