I've got it taken apart right now. I have a Gen II LT1 383 to go in it with a T56 to replace the TH400. Putting in an EFI Connection coil on plug system with the 0411 PCM and trying to figure out how to cram a centrifugal supercharger in it with an intake that uses the L88 hood. I'm expecting around 650hp if I do the supercharger, but I may tone it down a little and shoot for around 500 NA. I don't really need more than that and there's really no good way to put an intercooler in one of these.
