Since you folks know more then me, help me to decide nice camshaft with better torque\hp 1000-5000rpm, but with smooth idle(so i guess no more then 260 duration) i d say most agressive but with smooth idle

Heres what i dug:
Stock 96 n up (L35) 4.3 (vin w)
rocker 1.6(Not sure! could be 1.5 or 1.52)
intake valve lift - 0.444, exhaust valve lift - 0.458
0.470 is max valve lift on the OEM springs and rockers

this all came from a few sources, tryin to determine it also here, in fresh topic
