91 rs 305tbi to tpi ?
I have a 91 rs 305tbi and can get a polished tpi w/wire harness for good price, but its off a 350 will it work w/my 305? how much will I gain if doing so?

I would say you gain nothing but flash...
Use your money to optimize & tune your TBI...

TPI was originally built for a 305ci engine. If it came from a 350 you would need the 305 injectors, TPI fuel pump and a TPI ECM with the 305 prom, if you already have the complete SD TPI and harness.
There some good treads in the TPI forum for this conversion.
