intake a gear change are both way easier than changing the cam i would try both of those first. maybe the power band is different than the last motor?

i would start by advancing cam 2 degreesComment

You've got a 2 barrel cam in that thing. Get something with some duration and lift and you'll notice a big difference. A cheap, good running cam is the JR 109. I've won a lot of races on that camshaft in a 383. Your heads are only going to hurt you at top end. I run the Super Victor on all of my motors.Curious that we spend more time congratulating people who have succeeded than encouraging people who have not.Comment

sounds like a howards cam we ran for years in a prostock and only turned 7000 and won alot of races.now in a modified same engine only track one heads on alky and still only turn it 7400.I think maybe you are turning it to hard on exit and spinning.just my opinion. we run 5.37 gears on a 3/10th trackComment

We went to practice last night with the victor jr on it helped with throtle response but we lost straight speed. it seems when we come off the corner im only gaining about 2000 rpm. Do you all think the cam is done? if so i would need to go down in gear or retard the cam? im not spinnig the tires wish i could lol.Comment

The cam is restricting the engine. That's something I'd have ran in a B-Mod.
It's worth the time to switch it out. Try the JR109. Everyone hates cheap camshafts but for the money it is the best thing you can buy. I've run it in 355's, 383's, 377's. Once you do that you'll see a pretty big improvement on power and torque. That 383 should be able to rip the tires off it with the parts you have in it and the heads/intake combo.Curious that we spend more time congratulating people who have succeeded than encouraging people who have not.Comment

Springs could be dead, replace them also with the onse that match the cam.Comment

Valve springs were good. We retarded the cam 4 degrees on the crank and it was 100% better. We found out we were coming of the corner at a higher rpm than we thought so we were running out of cam early with it advanced. Thanks for all your helpComment

so where do you have the cam degreed at now? i thought in the original post you had it at 102? so you took it back to 98?Comment

It was at 102 that is 4 dregrees advance from the 106 ic we moved it back to the 106 to move the powerband of the cam back up in rpmComment
