This was my first time swaping a cam. I left the heads stock on my 305, but i installed the following:
-Pistons Std. Bore Size 3.766 Comp.. Height 1.54 Pin Diameter 0.9273 offset
-Comp Cams Magnum Camshaft, Hydraulic Roller Tappet, Advertised Duration 280/280, Lift .525/.525.
-Rocker Arms, Stud Mount, Self-Aligning, Roller Tip, Steel, 1.52 , 3/8 in. Stud
-Valve Springs, Dual, 1.430 in. Outside Diameter, 322 lbs./in. Rate, 1.150 in. Coil Bind Height.
-COMP Cams Pro Magnum Hydraulic Roller Lifters.
-Carburetor, Quadrajet Stage 2, 750 cfm, 4-Barrel, Spread Bore, Single Inlet.
-TH 350 Shift Kit, Transpak, GM, TH350C
this is my first time working with this kind of modification and I spent a several days looking for answers about the adjustments or settings for this configuration,the engine is running, it feel great but not perfect,adjusted initial advance time to 10 degrees, the mixture air/fuel is too rich, you can smell gas, the intention of a big carburetor and a big cam is to place turbo, What would be my best choice for a turbo? I would like to know if the combination mentioned is correct? If you have any comments or some knowledge about this, for example advance time adjust, I would appreciate your opinion. Thanks in advance.
P.D.I would like install a Ignition Box, MSD 6AL-2, Digital CD, with Rev Limiter
