Race cars and tight budgets are incompatible. Our experience has been to double whatever budget you have created and it might be close.

just get the Street Twin, you will regret it later if you dont. also the centerforce DF for the LT1s is junk. i have been through about 5 or 6 different clutch combos on these cars, and on my last 3 6 speed combos have gone with a street twin as well as using them in local cars i work on. only down side to it besides the price is that the ST is real hard on drivetrain and suspension parts if yours arent up to the task.
IMO the 48lb injectors will be a little on the small side unless you are planning on a superfueler or other means of adding additional fuel. i currently have 42lb injectors with a maxxed out superfueler (3-24lb injectors) and the 42s are running 28+ms pulsewidths so its time to step up. i wouldnt run higher fuel pressure to make the injectors act bigger since that will reduce the performance of your fuel pump which is already on the small side (pumps flow less volume at higher pressures)

Since your prepping the block, go ahead and have it receiver grooved or o-ring'd, and drilled and tapped for longer and bigger (9/16) heads studs.

This block will not need it. There are a handful of guys making the power that I'm and I none of us did this. I know two personaly, for that matter.
