Gentlemen. . .I think we have a winner. The 10.5 power valve came in this afternoon. The stumble is gone. That said, I bet I can now go back to a little smaller squirt nozzle 41 back to a 37 and a smaller acel pump cam. Just happen to have both from all the early tuning I was doing.

Jeephammer and TKfireman. . . . thanks for the technical support along the way.

Can't say enough about team rush upgrade, runs better and idles a bit smoother than it did with that no brand name HEI the PO installed.

One question left. . .the MSD street fire box has a rev limiter. As you know a fresh rebuild, balanced with upgraded heavy duty valve springs etc. etc. etc. I set the rev limiter at 4800 RPM. . . .to high . . . .to low?
