I built a engine for my 84 crossfire. I ported my stock manifold and used this camshaft:
Cam Style: Hydraulic flat tappet
Basic Operating RPM Range: 2,200-5,200
Intake Duration at 050 inch Lift: 222
Exhaust Duration at 050 inch Lift: 222
Duration at 050 inch Lift: 222 int./222 exh.
Advertised Intake Duration: 290
Advertised Exhaust Duration: 290
Advertised Duration: 290 int./290 exh.
Intake Valve Lift with Factory Rocker Arm Ratio: 0.447 in.
Exhaust Valve Lift with Factory Rocker Arm Ratio: 0.447 in.
Valve Lift with Factory Rocker Arm Ratio: 0.447 int./0.447 exh.
Lobe Separation (degrees): 114
This cam works great with the stock computer. I do not race my car, I just wanted it to run a little better than stock and it does what I want.
This was made by Sealed Power CS179R and available from several different vendors. It has the same specs as the old 327 350hp. camshaft.
