Hey Mike; Yeah, it sounds like the pump sh_t the bed on you. If you deside to go with either short block, I sent you the specs for, I would definetly replace the pump. I woud hate to see you damage either one of Dave's comp Hawk short blocks. With a Kenne Bell or Whipple, the 5.1 stroker, a good tune, running a good set of slicks, and 19-21lbs. of boost will definetly put you in the 10's with ease, Mike. Did you get the copy of the email, I got from Dave w/the specs on the two Comp Hawk short blocks?
