i would send it out to get rebuilt. A&S, F.A.S.T, K&T, McCoy, HJR, Insane, Clown, D&M, WKR, RDZ, packard, just a couple of options. if there are some that i left out please add them. these are some of the top builders in my eyes. everyone will have an opinion on who does theres though. as far as dyno's dont have a clue of whats in your area. good luck and keep us posted.
