trinity stage IV pipes, K&n with billet adapter, airbox no lid, 200-600 ft, and i just bought these cylinders from a guy on here, they are A&S duneport bored .040 over and thats all i really know about it, and a stock milled head? estimates? also one more thing my jetting right now is pretty dead on before i put the cylinders on, it was a 320 main stock pilot and one cilp up from the center on the needle, it was a dynojet needle. Im thinking a 350 main, maybe keep the needle the same and go up one on the pilot to a 27.5 to start with? good idea?
