Be careful with the shops that don't know turbo buicks. These motors don't like the traditional clearances that a small block chevy does. If you take it to one, do your research on here first and take them a list of what you need your clearances to be. Too many times I have seen guys take their motors to run of the mill places and trust them, only to have low oil pressure or worse. Depending on what is wrong with yours, you may be able to get away with a crank polish, run a .001 bearing on rods and mains, maybe even a hone and ring job. I would bore and hone it, use new pistons, polish the crank and use .001's, get new gasket set, have the heads reconditioned with 100lb springs, new cam like a 204/214 hydraulic, etc. Could be a low budget build, while still meeting your goals and not killing your wallet.
