that cam is fine. oh youll be in the 500's. if i had to guess....if i knew your exact mods I could get really close to your actual number. pulley size would be nice to know too. you can buy my 4.13 and make 8-10lbs.

 

Power related I have that cam, 1 7/8 headers slp exhaust, y pipe, not sure if the heads were ported or not...ls6 block mahle pistons compstar rods...don't know if its forged or not...doubt it...nuts its a used block with new rods and pistons...that's all I know about it...I bought it as is...oh and 3.73 gears, stock 10bolt in an a4

 

But* not nuts

 

How much for the pulley?
