Ok, I think that in your case I would suggest a speed density system. You're gonna need to do some major modifications to the TPI setup later on for it to be able to feed that stroker. One of which would be to get either a high flow MAF sensor (stock is a pretty big bottleneck, and high flow aftermarket MAF sensors are VERY expensive) or to swap to Speed density.

You'll need bigger injectors (Ford 32 #/hr injectors work very well for a hot 383), aftermarket high flow runners, a ported upper plenum, bigger throttle body, and a new high flow TPI intake (basically replace all of the original TPI parts, less electronics). Speed density is a more effecient setup, and will get slightly better economy / produce slightly better power. Now, here is the part that may make you happy:

This ebay auction comes with everything you need to convert any TPI setup your bought over to your 350, all you'd need would be some 22 #/hr injectors and a VSS (can be bought from Summit for something like 50 bucks, the seller says he'll help with that)

Basically be able to plug it in and go this way, then when it comes time to swap over to your new setup, you'd only need new injectors, new / ported TPI intake parts and the new "hot" chip to get it working with your 383.

Its expensive, but just for the included sensors alone you'd be looking at around 250 bucks.

I've got a brand new never used fuel pump I'd be willing to sell you (150 psi @ 43 gph, stock TPI pump is 50 psi @ 25 gph) for 100 bucks US shipped, I paid something like 200 bucks for it when I bought it, but I decided to go with a stock EFI tank from a TBI Suburban with a TPI pump I bought to replace it, bit quieter than the inline pump I'd sell you.

So yeah, you'd basically only be needing a VSS and injectors, fuel pump, and TPI intake then you'd pretty much be good to go
