You could go with an HSR and use a TPI computer and aftermarket harness. You could also run TB injection. I had an HSR on my Vette and loved it. What is it going in? If its a TPI car you can use the old set up but it will be a restriction. Another alternative if you have TPI already is Large Tube Runners and a better or ported base and plenum.

Totally different ball game now.. There are people who have adapted the LT1 Intake to run a traditional distributor and use a remote thermostat. Hopefully there is a better answer for you.

Would have been a lot easier if you mentioned that at first.
Unlimited choice of EFI intakes for your engine but you have to consider how you are going to control the injection ; nothing will work with your '92 LT1 computer because no Optispark on your new Reg SBC
( would have been better to buy stroker LT1 engine ; a drop in fit to your car )
So as it stands you run the carb or get a different computer and wiring harness so you can run EFI

Read my lips
Intake choice is not your problem
None of the LT1 engine electronics at present in your car will work with the earlier 383 engine.
Either need the computer and complete wiring from a earlier TPI car
or a aftermarket EFI setup like FAST , etc

Since your present setup is a carb, just throw the new motor in and run it for a while. Spend some time and do some research and collect parts. Then when you are ready to swap out the carb for fuel injection, you will have the knowlege and the pieces to make it work. You could get the new motor running this weekend. My .02. Willie

you need the computer and engine bay wiring from a 90 -91 TPI car ;it being the closest to your 92
(and just because your computer looks the same you can't use it on anything except a LT1 engine )
Possibly cheaper in the long run and easier to convert to a LSX computer

As noted;
if you had bought a LT1 stroker , everything would have been a drop in fit . no mods needed.
What you are doing is a very hard expensive option to the point where I would just run the carb setup as is
or get a proper LT1 383 ;you already have the correct LT1 EFI manifold on your old engine
and the computer to run it

.......... It sounds like its already too technical for you ........ pull the guts out of the stroker ... ie , the rotating assembly and install into your existing LT1 block ... the cam won't fit the LT1 but they're not that expensive to replace ....... some Ebay deals aren't deals in the long run ... research before you buy ...............
