With a TON of help from Tunedperformanc and some other great members on this forum. I've decided to go with speed density TPI setup. I have the factory TBI harness I need to convert and donor harness with all the injector plugs I need to use, F body fuel rail, high pressure fuel pump and lines from donor car, 9th injector delete kit on the way from Ebay to drill and tap for a dedicated MAP sensor signal, I found a complete exhaust system (headers to tailpipes) at local junkyard I'm getting in the morning, custom programmed memcal in a 730 series ECM, stock dual air intake element (still needing 90-92 speed density rubber boot), and found out my donor car also has a 3.42 rearend I'll be swapping in too (non-posi unfortunately).
About the only thing left I believe is a new set of injectors as a precaution but I can't order those until my snowplowing check comes in the mail.
I'm still just in the gathering mode since I'm held up replacing floorboards and inner fenders, Once I get that done everything will go together quickly.

Now I feel stupid. I started a thread on "3rdgen.org" after 1 or 2 things I asked on this forum weren't responded to and got help on one of those threads. Didn't realize in my email notification which forum it was. This forum is still great but I got the 2 mixed up.

dont forget the fuel pump. the tbi pump is only rated to 15 psi, you will need 45 for the tpi. i would suggest getting a holley pump and a new sending unit. i put the holley in my car, but the 25 year old wiring on the old sending unit lasted 1500 miles until it melted. never blew the fuse and thankfully didnt catch on fire.
