oldturtle Posted May 6, 2004 Report Share Posted May 6, 2004 My comp with stock motor was 105 psi at sea level so at this time my jugs and head are on their way to Patriot Racing in Sumner, Wash. for a bore, their hot trail spec porting, and their full head deck and squish fix for 91 oct Cal pump premium. I was very happy with the worn out motors power so this is gonna be like a dragster to me. Quote Link to comment Share on other sites More sharing options...
