Hello,
I have bought a ATI Procharger P-1SC to fit on my Buick 350ci engine (from XS Performance).
I d like to know which camshaft will suit the Procharger?
Compression? 8.5:1 Current Horsepower? stock +- 220 HP Desired Horsepower? with 500 i'm happy, with 600 grind on my face.. ;-) Redline (or shift point)? don't know yet +-5500 Elevation : seal level Cam? ?? i found this,:TA c113?? ( .488" - 228'/ .493"-247' / 113 lobe) does it suits ? Intake Manifold? TA Performance Exhaust? TA Performance headers (ceramic coated) with Flowmaster 2.5" exhaust and Super 40 mufflers Cylinder Heads? stock but ported (perhaps bigger exhaust valve ) 3 angle valve seat job Carburetor? Quick Fuel 650CFM Fuel Octane? 98 or 95 but i don't know if it's the same value as you have in USA.... (some pump in Germany sell 102 ) Converter ????
I was in your shoes a few years ago. I gave up on asking the cam grinders for their advice. They all gave completely different suggestions. What I finally did, that yielded great results, was spec. the duration and lift like you were building a strong street motor, but go with a wider LSA...like 114*. I tried 4 different cams until I settled on the found the best one. Don't go too crazy with boost unless you build the complete engine to handle it. Stay under 10 lbs.
