Basic idea of what I'll have to do to swap 305 to 350
I have a 305 TPI in my 86 Trans Am and I found a 91/92 350 firebird that runs for $300. I'm thinking about swapping it but what am I going to have to swap besides just the motor? What else bolts up, etc? I just need ideas so I can search TGO easier.

Knock sensor
injectors

Try a few searches anyways. You should be able to to come up with tons of threads with your very first try. With the new server searching on TGO is awesome.

There were quite a few changes in the TPI system from '86 to '91. MAF to SD, cold start injector to none, different angle bolts for the base mount, etc. I think I'd go for complete harness and computer change as well. Keep all the sensors with the harness being removed/installed.
