racing beat holley mods
I was wondering if anyone can tell me what mods racing beat does to their holleys? Such as what jetting they use on primary and if they change the metering plate on the secondary to allow for jet change (and what size jets used). Do they change the accelerator pump volume? Is this classified info and am I wrong to ask it? Let me know. Thanks.

A friend of mine bought one just to dissect and compare it to a stock carb and he said they do a shitload of mods to it. Air bleeds are all different and certain vaccum holes are different from the stock holley carbs. Basically he broke it down that it would be hard as hell to duplicate unless you had pin indicators and measured each and every hole inside that carb.

I use a regular holley 600dp on my 12a bridge and it seems to work fine. I had to put really small pump squirters in it though. I also ported a plenum into my RB manifold, which I think helps.
