I have a 83 chevy k10 with a 350. Recently it was rebuilt with all new parts. Running like 1:9 compression on 89 pump gas. Got it timed perfectly but something still isnt right. It starts right up and runs great at idle and revs up normally. When you take it for a drive it doesnt pull very hard and it feels like its pulling a heavy trailer. Doesnt want to get past 4000rpm and takes awhile to get there. Has brandnnew msd distributor, msd plug wires, new spark plugs, edelbrock 1405 600cfm carb that was just rebuilt. The valves are adjusted perfectly and i had a mechanic check them over and he said they were right.
