I just put a new top end on my 4 mil setup. It consist of .20 over passion 4mil 12 port drag cylinders (stock), Boss intake, 35mm pwks, chariot cool head with 19cc domes.
The guy i bought it from said it run best for him at +7 timing with 162 main and 50 pilot at 750ft elevation. I am at sea level. Also he was running shearer oof drags and im running cpi inframes.
I jetted it like that and I cant take off in second without it bogging and if i take off in first it turns up quick but when i shift to second sometimes it boggs and also 3rd.
