Opinion from some of you long time Mopar racers

It's not going to go faster with a 950, but getting that 1050 dialed in is step one. Easy to do on a dyno with an AFR gauge.

Run it, set the lash to .022 and run it again. If you are really concerned about it, run it at .024, then check the hot lash. That will let you know what you have to play with. You'll know right away if it likes the tighter lash. Easy to do on a dyno. '
