Looking for a chrome 9" vac booster
Going from manual drums to front discs (Wilwood/CCP), have most My parts including Wilwood MC/proportional valve. So the engine is a 454, Oval port heads, tall valve covers, and a single diaphragm won't fit. Rear discs down the road. Engine has a CompCams XTREME solid lifter cam, lopey idle.
I'm thinking the next best is perhaps a 9" dual diaphragm unit unless somebody tells me that a single diaphragm would be more effective. Looked at TuffStuff, but their web site doesn't work well with alternatives, they keep insisting on the stock size 11". Probably have to call them to get an answer on what booster, mounting bracket, and threaded rod we need to make it all work. And... I'd like the booster to be chromed, but don't want a no-name from eBay with no tech support.
Anyone want to chime in with what they used, how it worked out?
