well 500 horse is a lot different than 600 horse. So you kinda got to make up your mind. 500 horse is relatively easy. You can use a stock cast crank and regular rods,(better rod is better but not necessary. As ususal it all needs to be put together right. You don't need forged pistons either but just like the crank and rods, it won't hurt to get good stuff. about 9.5-1 compression with a cam that will work good with the compression you are using. Some decent oval port heads, 049's, 781's, or 063's, you will also need to decide if you are going to go open or closed chamber depending on what piston you are using. I would highly recommend a decent but basic port job on the set of stock heads. A perfomer rpm/air gap, 750 double pumper, 1 3/4- 1 7/8 headers and a cam of your choice something with about 230-240 @.050 durtaion with about .550 lift. hydraulic or solid. Get a good recent grind cam, like a LUnati or comp extreme. THat will get you an easy 500 horse. If you want 600 horse go with something like a Brodix oval port, AFR 305CC, edelbrock roval port 290CC(bottom of the barrel head) Canfield 310CC, bump the compression up to 10.5-1, bump the cam up accoridngly and go with a solid flat tappet or roller, and maybe a 950HP carb. OBviosly there are more ways to go, but those are pretty basic setups, let us know what your HP goals are exactly and how much money, what kind of use, and drivetrain
71 formula firebird, 468; AFR rectangle port, 11-1 compression, Isky Solid Roller 290/294,...620HP, Viper T56 six speed, 19" CCW rims, Hydroboost, C5 corvette brakes.. currently being built(almost done)
