UPDATE...I bought a timing light and have been playing with it for a couple weeks now. I set the timing at 14, 16, 18, and 21 degrees advanced. It seems to run better with 21 degrees as far as low end. I jetted the carb down as well and theres no more smoke when flooring it. I didnt change the plugs because they looked fine. I changed the alternator because it was only showing 11 volts and the new one shows over 13. The truck runs pretty good but I would think a 350 in an s10 would be faster. I am thinking of dropping the single plane intake for a high rise dual plane and changing the rear gears to 4.10 from 3.42...any thoughts on that?
AT 2,500 I WOULD TRY TO HAVE MOST OF THE ADVANCE OUT.I WOULD TRY TO FOCUS MORE ON TOTAL TIMING.I WOULD START AROUND 36 MAKE A PASS AND SEE WHAT IT DOES.DID YOU GO FASTER?OR DID IT GO SLOWER?REMEMBER TO ONLY MAKE ONE CHANGE AT A TIME AND WRITE IT DOWN.YOU NEVER SAID HOW MANY R.P.M.'S. YOU LEAVE AT.ARE YOU TRYING TO (FOOT BRAKE) THE CAR TO 2,500 IF YOU ARE THEN MOST OF YOUR INITIAL TIMING WILL BE OUT.DON'T FORGET YOU ALSO HAVE THE WEIGHT'S AND SPRINGS YOU CAN PLAY WITH.3.42 TO A 4.11 IS A BIG JUMP.IF YOU CAN'T HOOK IT UP NOW IT IS ONLY GOING TO GET WORSE WITH THE GEAR CHANGE.
