305 to 350 swap questions please help
Ok I've spent the last 4 hours searching threads on here and kinda hit and miss on a couple things was wondering if y'all could possabily help clear them up.
1. I have a 91 z28 with 305 tpi with the t5 trans, I just bought a 350 tbi out of a 92 1500 pickup and I'm going to swap my tpi set up over and replace the tbi.
2. I know I need differant injectors, knock sensor, and a prom whatever that is and that's my first question what is the prom??
3. The other question is what else do I need from the donor truck? Like computer and wiring etc...
4. What can I use off my tpi set up on the 350
Thanks for any help y'all can give and if ya give me a hard time for this topic being over posted then I'll take the criticism cause I probably deserve it but I want to do this swap bad

Re: 305 to 350 swap questions please help
the chip ( blue thing ) inside the computer.Take your 305 one out and install a 350 prom
Nothing ( unless you want to install TBI in your car )
Everything
All you are doing is swapping a different engine under the intake so nothing changes up top
350 TPI identical to 305 TPI except for the 350 specific items you already know about
