--------------------------------------------------------------------------------
I have posted on here alot and got alot of good info so time to get this one fixed.
I just built a new bottom end and put my heads on it with a new cam and super vic intake
We just got it off the dyno Thursday and dropped it in. Ran great on the dyno using my MSD box, Coils, Wiring harness, sensors and carb. Dropped it in car and from the very first pass it will start stumbling really bad about 5600-5900. Just does not want to pull past that. Any ideas what to check? Just spinning the motor over in park it revs to 7000. So its when it has a load on it. (burn out and going down track) It will make a pretty good pass as long as u shift it about 5300.
LS
Hyd cam
supper vic intake
6LS msd box
Pro systems carb
We changed MSD box , coils , carb, ran new power and ground wires from battery to box and check fuel pressure.
My carb on the dyno was going lean in the upper RPMs but still pulled to 6900. I put a diff carb on it while at the track and same thing.

Its not the best vid had to hold phone drive and shift. This was just pulling out on the street and getting on it. It will do it that quick everytime. Keep it below that rpm and it runs great. Stumble is at .16-17 in the vid
starts at 5500 RPMs
