So I have an 85 k10 with a 305 with a 700r4. I know its a 305 but Im trying to get some input on why my engine is running rough.
I put a new summit SUM-226014 Stage 2 intake, a new summit 600CFM carb, a summit-1065 ADV duration 284 .05 duration 218 .458 lift and 110 lobe separation cam, lifters, valve springs, and distributor. Right now I have the timing set at about 22 degrees BTDC at about 650 rpm in drive. It seems to want more and runs better with more timing. I tried 18 because I have 18 mechanical to give 36 total and it ran like a dog could barely make it up my drive way (which has a slight incline) the more I advanced it the better it ran. With the 22 degrees it runs better but wont go over about 2200 RPMs or so at WOT It hits the 2200 and just flattens out. At 22 degrees it starts fine and doesnt ping.
