I installed the 3200 spring. Seems to have more pep. What adjustments are necessary to take full advantage of the rpm gain? It seems to run out of fuel when it approaches 3000 rpm. This is in the 91' with a 5 speed and 354's..

 

Back the high speed limit screw out all the way and make sure you are getting full travel at the pump when the accelerator is floored.

More timing would be a good idea if you haven't bumped it yet. You may also have a weak lift pump.

 

Thanks, Dave... lift pump is pretty new but that don't mean it ain't weak... that will be my next gauge....

 

Is that as per Cowboy Custom's sticky on the Fuel Screw...screwing out one half turn at a time, snapping the throttle till it starts to hang up and then screw it back in? Thanks again... rockfoot

 

I'm talking about the high speed screw that limits throttle travel, not the power screw.

 

Advance the timing , Aftermarket fuel pin , Starwheel down a turn, Back the "High idle" screw out a little.

I'll see if i can get pic. Its the screw that the throttle lever on the pump comes back and touches when its floored.

 

Ok, Dave...gotcha. Glad I asked!! I'll do that and then move on and attempt the timing... baby steps....
