Timing Chain Question??
Maybe a dumb question..... will someone explain the advantage of setting timing gears straight up ( not retarded like late model), after market gears I been looking at have three settings 4 degrees advance, normal, 4 degrees retarded........ could this not be offset by distributor timing???

As I understand it the retarding was to help pass emissions testing. If you don't have strict emissions testing where you live you would probably do well to set it straight up. The timing chain is for the camshaft in relation to the crankshaft, you could only partially make up the difference by advancing the ignition(distributor) timing. Just the way I see it, hopefully you will get more replies.

Cam timing changes will alter the TQ and HP curves a cam produces, the amount is pretty small though. Advancing produces a bit more TQ, retarding produces a bit more HP. It's usefull to tweak a particular combo for a desired application, but it's far more effective to just use the cam that produces the desired powerband and install it straight up.
