This part was edited after I saw Todds post deleted when I posted mine.
Todd, I've posted right behind two of your post tonight on different threads and by the time mine posted yours had been deleted.
You do that or somebody else do that?
I ran a BBC with 502 GM block, Eagle 4.25 crank (548ci), GRP rods, JE pistons 13.8 - 1, world products heads (not the best choice, but Curtis at RFD got 399 cfm out of one and 400 out of the other head), Comp cam, and a vacuum pump and made 868hp. Don't spend as much as I did on the heads, use eagle H beam rods and you could be at 700hp no problem within a decent budget. My motor ran for over two hard racing seasons no problems.
