BIG PROBLEM! the 83 351 was the epitome of the smog motor! There was no such thing as performance in the 1983 351w! It had a weak flowing set of heads, 8.2:1 compression and a camshaft with less than .400" of lift. Before you run to a carb and maybe pick up 2/10ths get a real set of heads, and an edelbrock performer RPM cam. The intake is a bigtime mismatch for the current motor, so are the 3" pipes. I'll bet that with the cam and a set of heads and no other changes you'll be deep into the 13's.
