350 tpi mods
i've read that putting vortec heads w 1.6:1 rockers, an accel/lingenfelter 74211 cam & retarding the timing 1.5 degrees works really well on these engines. can anyone tell me if this is true? and why would i need to retard the timing? any input would be great. kelvin.
Welcome to CHR. I think that you need to hook up your vacuum advance. At part throttle when cruising you have less air and fuel in each cylinder, and the air-fuel mixture is not as densely packed...
