Fine Tuning a 360 Magnum with a Brawler "Double Pumper"

Okay that makes a lot more sense.

Update for ya gents, I just ordered some blanks and .028IFRs. Going to tweak one thing at a time. Well I guess two in this case. Blocking the middle emulsion holes, and removing the top .031 IFR and replacing it with a .028 on the bottom as Turk recommended.

I cant get any brass set screws locally and soonest I can ship any is next week, winter storm surely not helping, so t-slot restrictors will come later.

I do have a question that may have been answered but I'm half asleep and wrapping up my thoughts: is the pump shot an entirely independent circuit? As in the changes I'm making won't affect the stumble if the pump shot was an issue?
Yes it is its own circuit. You probably want to try a bigger shooter for what it's worth before drilling ****. I'm saying this because we're talking about a stock cam engine with a ton of vacuum...
