You may want to think about finding you a 292 and build from there. and bore it either .030 .060 over for even more cubes(298/302)and install a cam designed for a turbo. Most stock cams or Rv type work very well with a turbo. And i think you will be happy with the power & tork Your looking for. hope this helps }[oooooo]
