I've got a 390cfm Holley and was wondering if it will work on my '85 GSL 12a with a RB manifold? Or should I wait and get the RB Holley?

It'll work. Racing Beat uses a modified Square Bore Holley Carburator. Which means any Square Bore Holley/Carburator will work. I currently have a 600CFM Holley for myself.

If it doesnt fit, there are adapters out there.

I meant will it work with the stock fuel delivery or will I still need to upgrade to a larger fuel pump? The stock stock carb flows somewhere around 390 or so doesn't it?

yeah. it should work. i ran my 600 with the stock fuel pump for awhile. but if it doesn't. i'll buy that intake you just bought. ha ha ha.

Holley Red Fuel Pump will do. Thats what I gots. I heard the stock one will run out of fuel at the end of a gear with a Carb that size.

gotta say, the stock on mine with a good port at 130 in 4th hittin 8grand never ran out of fuel. but you never know. i have since went with a holley blue (just in case). was a good price also. but i'd try the stock pump at first and see what you got. if not, find one on e-bay for under 50.

and for news, well it was cool. found out after i transfered the money for it. wasn't the greatest thing to hear that someone came by and bought it with cash today. but the money was returned befor i even knew what was up. i'll find another.

good luck with it. if you keep your stock omp. i have tapped some fittings into the intake itself to run the lines. works great. got the fittings from atkins. if you want i might be able to find a pic.
