Hey guys:
We have a vehicle with a late 70's 360 in it and I guess we need some tuning tips.
The engine is fairly fresh, with Performer intake, 600 Edelbrock carb and LT headers. We didn't do the work.
The problem is a pretty severe stumble that lasts about 1000 rpm up the band.
It's not a tip-in stumble. You hit the pedal and it'll take off for 50 feet, then starts to hesitate and stumble, then finally pulls itself out of it and goes.
It had a #1411 750 E-brock on it and we initially thought that was the culprit since that's a too-big carb and those haven't had a good track record.
The 600 is known good, and it cleaned up the running a lot(leaner), but still has that low-midrange don't wanna go thing even after the carb swap.
The engine seems lazy even when it's not acting up, and the issue is predictable....it cuts up the same place everytime.It starts and idles fine and it doesn't seem to run bad at cruise speeds.
The place we haven't touched yet is the distributor, so you guys think something might be amiss in there?
