I am in the process of rebuilding my old tired 1986 460. I have just bought a set of 1973 Linc. heads for it, and a Edlebrok intake and 750 CFM carb, new race pistons, rings, gaskets, and bearings. I mic-ed all the culenders and see that they are almost like new, and the stck crank is like it was never used. This engine has very little miles from what I can tell. The question I have is on the cam and lifters and rockers. My goal here is to hit 500HP, but anything close is acceptable. I see alot of cams out there, but I know very little about them. With the setup I have so far, can anyone recommend a cam? Summit Racing has some really nice prices on cams and lifters, under a 100 bucks, are these any good? I will be running a Warner T-18 4 speed, with a 3/4 ton rear end. Also, with the addition of a new cam, will I have to have different rockers? I am kinda on a budget, and wonder if there is any great gain by aftermarket rockers with rollers or if the stock style will suffice. BTW, I have bought new pushrods and guideplates. Any info anyone can give me on this project would be great. If there is something I should know, and I didn't ask about it, please feel free to let me know.
