305 tbi to a 305 tpi swap HELP PLZ

Hey so i bough this z28 motor from an 86 that has 27k original miles. Its the TPI setup and i have the TBI setup. But i will be getting everything from the seller to include the ecm. Basically everything that goes to the engine he is selling me. I know that all i would really need now is a wiring harness, but is it more worth it to just take the top end of my current engine and swap the bottom end of the motor i bought and keep the tbi? the tpi just looks more appealing to me... Thoughts? Anyone do something like this before?

You can rework a TBI harness to suit TPI
