I have a Holley 9022 800 CFM DP on my 454. The base plate is worn creating a small vacuum leak around the base plate that randomly wants to leak or seal... Causing all sorts of grief idling and around the docks.
I was considering getting a kit to bush the plate but that cost almost as much as a new base plate and I'd hate to not ream it out straight. Forgive my ignorance but is there any difference to a marine base plate than a normal automotive 4150 base plate? The 9022 specs on Holley's site mentioned sealed throttle shafts. I don't see any reference to the 9022 carb on Summit or anywhere else I've looked at base plates. Does anyone know is a standard 4150 DP Holley base plate will work? Any advantage to go with a Proform or similar aftermarket base plate if a standard 4150 plate works?
I called Holley today and they didn't have an actual part number for that specific base plate but could get me one, though they likely don't have any in stock and it would be made when they get around to another run of those... Up to a month before it would be made and shipped out. I asked if this part was interchangeable with a standard 4150 DP plate and the tech wasn't sure.
I asked Proform if their 4150 DP base plate would work and they couldn't tell me for sure either way, said to ask Holley.
I'd prefer to get this fixed quickly since my season has started, but don't want to spend $500 or more on a carb when all that's worn on mine is the base plate. I may rummage through my parts carbs to see what I have and what I can compare it to. If anyone has run one of these carbs and can tell more than I've found so far, that would be great!
