Hey guys, Great loking site here. I have a question I'm sure someone can shed some light on for me.

I have a 88 chev stepside 2wd that i'm in the process of giving a heart transplant to. She will be getting a 350 ci, TPI from a 86 vette.

After reading about the differences between MAF and MAP systems I'm pretty sure I wanna use a speed density setup. So I'm thinking about buying a painless tpi wiring harness and getting a piggy back chip for the ecm to change some settings such as vats, emissions , etc.

My question is are the distibutors on the two types of TPI setups the same? also other then not connecting 9th injector, removing maf sensor adding map sensor, and changing the knock sensor is there anything else that I have to do?

I'm going to be useing a 700r4, and read something about the vss needing 4 pulse instead to 2 pulse setup, how would I go about changing that?

Also if anyone has any reccomendations as to where I can maybe save some dollars on the "painless" wiring harness that would be great. thanks again and looking forward to getting your input.
