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?
Before changing gears, definitly drop that single plane for a good dual plane like a Performer RPM. Seems also that the springs are now too tight in you advance curve Your having to set base so high because of how long its taking for the curve to come in and then by the time it does your way too high killing top speed.
