ATI Procharger Buick 350ci
 

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 ????


- stock crank,
- stock or better rods (still looking)
- heavy duty pushrod
- dual valve springs
- poston roller rockers
- hi-rev lifters
- ARP head studs
- Intercooler

Thanks a lot for your help

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. :mad: 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.
