I did some trading and ended up getting a 600cfm Holley 80457 carburetor that wasnt in the best shape but definitely rebuildable....or so I thought?
I purchased a rebuild kit and tore into the carb the other night, no big deal. When I got it down to just the body I noticed the coating was blistered and flaking off. It looked bad, but to me not bad enough to scrap it, because I figured as long as the passages were clear, once the gaskets sealed it wouldn't cause a problem.
I got it all back together, except for the secondary bowl because I was missing the secondary metering plate and wanted to call Holley to get a part number and order it. It was late last night when I finished up so I waited til today to call.
I talked to one of their techs and got the part numbers I needed. i figured since I had him on the phone I'd ask what he thought about the metal flaking off.
Much to my surprise, he told me that they recalled a bunch of these carbs due to plating issues causing the metal to blister. He asked me the date code and informed me that this was in fact one of the faulty carbs and that they will send me a brand new one
To me, this is awesome!! Not only because Im getting a brand new carb for practically nothing, but the fact that Holley backs their products and when a mistake is made they step up to the plate and knock it out of the park!!! Ive dealt with Holleys techs for a couple years now and everytime they have been very knowledgeable and have helped me out on a number of occasions. So, a BIG
thumbs up for Holley!
Sorry for the novel, but I just wanted to post in case somebody had a holley thats plating is blistering. If so, call up there and get them to check your numbers to see if you can swap yours out. Later guys!
