10s for 10k can i do it?

Nope. Wrong heads IMO. They will ned a bit of work to reach your proposed goal. Plus a race convertor. Then you have the cage, fuel system, new belts, SFI dampner, SFI flexplate, aftermarket axles... The Ross pistons will fit loose in the bores... they are supposed to be fairly tight. Did you have the block sonic tested BTW? If not, do that before you do anything else. I think overall, you have anotehr $6-7K to spend unless you are really hooked up and doing it all yourself. Still by the way, dirt cheap for what you'll end up with.

I agree with you on the 10k answer to this question, But this choice of heads in the right hands WILL be capable of making 600-700 HP depending on what other POISON you will be using in the build.

Bobby at BJR has my set of INDY/RHS X heads right now and without going too crazy the flows are pretty impressive for this casting even with a SMALL intake valve of 1.920, the flows are 293CFM @ .500 lift and over 300CFM at .600+. The exhaust was just cleaned up and flows over 204CFM + at .500 lift and above with a 1.60 exhaust valve.

Sorry to get off the subject a bit.......
