Timing question ?

[kauzenkaos]

The guys over at msd want me to find out what total timing comp reccomends for the cam i have and what rpm i need it by. My setup is a sbc 400 and only turns about 5500. Its in a 90 k5 blazer. My cam # 12-210-2 grind # cs 268h-10.

First off the camshaft does not dictate ignition timing. That is highly dependant on many other factors and should be tune in to whatever the engine runs its best at. I would start around 12 degrees initial and around 32-34 total advance. From there you will just need to tune to whatever the engine runs its best at. Total advance should be in by 3000RPM.

Thanks that should be enough to get me started
