Hi everyone, I hae a 72 Challenger with a 484 stroker, 440 Indy heads, M-1, 545 lift hyd flat tappet cam, that I currently have a Demon carb on. I am looking to change out the very finicky/unreliable Demon for a better carb. I have been looking at the Proform 950 Race Series and a 950 Holley Ultra HP. I am wondering if anyone has any experience with either carb series. I have heard good things about the Proform, and everything I have read up on the Hooley sounds like its a really good unit. The Holley is quite a bit more than the proform. Any thoughts? Thanks in advance.
