Talking to Danny@SEMA it seems his 72 has a destroked LS7 with solid roller cam.....probably makes mid/high 500HP output.....I see many people on here trying to build too much HP for the intended use of their cars. If your planning on autocrossing that Vette the LS7 should give plenty of power, going to a solid roller set-up will give you a little room at the top RPM range to over-rev between corners without pumping up hydraulic lifters. The problem I see with LS motors and high RPM is their oiling systems SUCK! You will need to pay attention to oil routing and massage the internal block passages to make a LS live at 7000+ RPMs for extended periods of time....on a Drag Strip you will never see the short commings, banging a motor against the rev limiter (if its set above 7000RPMs) like happens on a road course or auotX and you will discover the shortcomings of an LS.
I doubt that LT-1 will ever return to NCRS standards, if it were mine, I would go onto the Corvette Forum or NCRS Driveline and start selling some of those wanted parts....that windshield wiper motor has a rare 5 port pump unit on it....probably worth over $200 to a NCRS guy, the front grilles and headlamp surrounds on a 70 LT-1 are worth some money too if they are original.
The Ridetech 48HR Corvette (that turned into a 60+ HR Corvette because lets face it, its not as easy to build as an Fbody!) is a great reference on a decent C3 build. I intend to put a Greenwood 5 bar in my 72 LT-1 to deal with the rear toe change problems of the C2/3 Vettes, if your interested in info....Email me, I basically have 2 set-ups and might sell the extra one. This stuff was designed by Bob Riley.....pretty decent car designer.
