he told me that even haisleys dont use much bigger injector than that for thier pulling trucks making over a 1000hp said that 370's are about as big as he needs, i am taking that it was with that pump. my 95 with most of the same stuff i dont think will break much if at all over 500. let alone just barely maxing out a 500hp dyno then claiming 800hp because theres no proof that it didnt do it. he said he runs with haisleys and other big 800hp pullers so he has sompthing to compare it to.
