need tune up specs crate 350
I recently aquired a 86 K-5 blazer 4x4 with a good wrench 350 crate motor, 10067353, installed in 2001, it has 60,000 miles on it(originally had a 305 in it.) the standard 350, it has a carter afb 4 bbl on an edelbrock manifold, the guy who installed it evidently used the stock year manifold on it because it has the egr valve behind the carburator. this motor is actually intended for 74 to 85 i believe. I have gotten rid of egr and all the extra smog crap and am now down to the basic engine and running gear with cruise and A/C. I am trying to figure out what the best tune up specs would be to use on this crate motor, its an automatic with hei ignition, it has a carter afb performance 4bbl carb on it. ANy one able to tell me what are the best tune up specs to use and the best way to tune this carb. Thanks for the help. George.
