As much as I hate to ask for input sometimes a person can't see the forest for the trees.
I will, instead of listing everything I've done, give the known since.
69, 74" stock bore, s&so barrels, kb 9.0:1 pistons.
Andrews b2 camshaft, s&s super e, andrews 4.8 ohm coil, stock timer, auto. Recent rebuild. Compression at 115 and 120, seems low, could be cam.
Issue, starts, runs, sounds great. Around town great, no hickuPS, backfiring, sputtering, restarts great, throttle up at idle great.
When at speed shifting from 2-3 rpm climbs normal, if I let rpm reach shifting point and hard accelerate it hesitates, won't throttle past, holds its speed. If I am at the low end of 3rd gear and throttle hard it hesitates for a second and blows by it to reach 65mph , same in 4th, at steady speed feels great, try to steadily accelerate past 60 mph no go, slow down to 3rd gear and blast it to 65 then shift and try to maintain, it hesitates again.
I've tried a ton of things will answer if I get any takers/help on issue..thnx
