Hi; I'm considering swapping a 305 TPI to a 350 TPI in a 91 Camaro with an auto trans & I'm wondering what kind of things I'd need to replace. I'm planning on doing the routine, replacing the rear main seal, other seals, rubber hoses, thermostat, & fluids but is there other stuff that I need to replace while I'm at it? Also what stuff in the engine bay won't carry over when I'm swapping it? I'm not planning on doing much in regards to the suspension/chassis at the moment except for subframe connectors since it's a T-Top one (I am planning on getting a front and rear Detroit speed 1 kit later on but I'm on a tight budget. I am also planning on getting a first intake, cam, heads & headers however that will also be not until later

 

Straight swap, just need 22#hr injectors and a memcal chip for 350
