We got it to the track to day looks like we picked it up 60HP new best today 10.17 at 131 MPH I think old best 10.38 at 127 MPH I am happy it picked up did not change any hard parts other than (cam regrind) and I think still have some more left in it. the old best was in good air and the air today was not the best so I think it should go some 10.0s in good air. 10to1 pump gas engine not bad and low cost to go racing. We will not talk about my POS!!!!!!!!!!!!!!!!!!!!!
