I know how to figure total timing... now what?
I didn't have a tape on my balancer; but bought a timing gun with advance DIAL to figure out optimum timing settings for my 74 El Camino.
I set initial timing at 10° with my stock gm 2 bbl on a 350. Results showed a total of 35°.
OK, now what can I do with this info to increase power or economy?
My book says initial timing should be 8°@600 rpm. This figure seems dated when factoring in the high corn-fed state of the regular unleaded gas I have been using. Can my el camino with a mild cam (E-921-P) run well at, say 12°?
