Heads

John Bedore said

I am happy that you took time to give me a boost. I am like I said going with 71 340 pistons, stock exhust intake and thermoquad, What would you suggest for a cam and who would make it? I have heard bad things about Comp Cams from Mopar and Ford as I have a 66 Mustang too. I would like to run 355 gears or 391's I done my last 1/4 mile racing 30 years ago. Any help would be great oh one other thing I know you said stay with my 73 340 heads but another set of X heads has come my way with no valves or springs Bare is the word. I can buy for 450 + shipping. What do you think again Thanks ahead of time John.

I have been buying custom Racer Brown cams for years. Jim is all MOPAR even if he grinds all makes. I call and talk to Jim and he grinds me a cam. You have to be honest and know what you want your car to do. You also need to tell him the specs for your car and engine. My cars are more handling and highway cruisers. I've never been a drag racer, although a few friends are very serious drag and road racers. I personally don't want cam profiles that are hard on the valve train and require high spring rates. I'd rather spend the extra money on good machining and have the engine last than wring every last hp out of it. My cars are plenty fast for what I want. Anyway, there are other cam companies that can do the same thing, and I would definitely spend the extra money for something specific to what you want. The X heads flow better, and "if" they are in good condition, would be better. Worth the extra $450 + shipping is up to you. Bare is no problem, I'd be replacing valves and springs anyway, unless you have original 340 springs and they work for your cam. The 340 heads in pecking order are X, J, then your 73 heads. All can work very well with what you want to do.
