Looking for a few rough ideas from some people who have done a turbocharged 250. I will end up talking to a company (probably Crower or Crane for example) for more exact figures, but I would like some ideas before I call them. The motor will be for street/strip use, more street than strip. The transmission is a stock TH350 with a stock converter, and the rear end is a stock GM limited slip, for now. The motor will have lump ports roller valvetrain, and shooting for 8.5:1 comp. The boost will be around 5-8 psi for the street and maybe 10-12 for track use.
These are some rough figures that I have come up with as I am just trying to figure out as much as possible before I begin the build. Although everything is subject to change.
Thanks for any help.
