Well I had different springs so I changed them out, turned out that didn't fix it. Had a used gm module from a friend put it on and it works great again. I never saw that with the gm module before they either worked or didn't but at least it is fixed.
comp cam with 478 lift double valve springs, holley 870 street avenger. When it hits the 5000 and goes dead if I up shift to second its fine till I get to 5000 again. Electronic ignition, mopar performance distributor. timing at 20 initial 35 all in around 28oo rpms
secondaries do open, probably 3500 miles on rebuilt motor. Im thinking possible a week valve spring, or broken one? Doesn't matter if I take it slow or fast just stops at 5000
67 barracuda with a 360 auto, have been driving it for about 3 years with no problems, you could wind it up to 6500 with no problems but now it goes to 5000 and feels like valve float, just doesn't want to go further. Any sugestions?
In 1970 I had AAR cuda that 6 pk saw 8000 all the time, I was 18 yrs old. Now my understanding of the stroker motor is they make there hp at a lot less rpm. I would have though 5000 would be it on your motor. Just my 2 cents.
Timing alone may fix this, I would get your distributor tuned in first, than go to carb with a accelerator pump adjustment and you should be good to go.
I agree always use recommended springs and retainers. Any time you reach max horse power like 5500-5800 it time to grab another gear not to keep reving it just because it will.
