I’m going to rebuild a SBC 350 5.7 89-93 engine, I going to install the following:
-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.
- Valve Spring Retainers, Steel, 10 Degree, 1.500 in. Outside Diameter, .690 in. Inside Diameter.
-Valve Locks, Machined, Hardened Steel, 10 Degree, 1-Groove, 11/32 in. Valve Stem
-Comp Cams Pro Magnum Hydraulic Roller Lifters.
-Carburetor, Quadrajet Stage 2, 750 cfm, 4-Barrel, Spread Bore, Single Inlet.
-Adjustable Vacuum Advance Kit For GM HEI W/ Springs & Weights
-Ignition Box, MSD 6AL-2, Digital CD, with Rev Limiter
I’m looking answers about the adjustments or settings for this configuration, like
• Proper geometry (push rod length)
• Timing set phasing ( +4 Degree advance)
• Machining on cylinder heads.
Do I need use lash cap or shim for the spring? Common problems? Or failure heads? If you have any comments or some knowledge about this, for example Vacuum advance time adjusts or other considerations, I would appreciate your opinion. Thanks in advance.
