Alright I did the 305 to 350 swap a while back. Now I am in the process of a T5 swap. Now I wann atake advantage and finish the 350 swap right. I know that the things that need to change from a 305 to 350 is:

22lbs Injectors
Knock Sensor
ESC
Prom
Anything else?

Ive searched but havent found clear answers. Now the injectors and Knock sensor I know I can find. But what about the ESC and Prom? I have an 85. The 85 never came with a 350, so what car can I use as a donor? And does my car have an ESC module or is it part of the ECM? What about a Prom for a 350? What car can I get that from?

I feel that I am not getting the most out of my motor. I know it can run better with the right parts.

 

no one?

 

350 TPIis didnt come in to production with camaro/firebirds untill 87. they can be found in GTA, formula 350, Z28 thats it, u can tell bc the heads are centerbolt, with centerbolt valve cover or the 8th(maybe 10th lol dont rememeber) digit in the VIN is a 8 and not a F. also 85/86 vettes came with tpi350 up till whenever, i think the proms swap over. but dont get proms made in after 89 bc they have VATS (vehicle anti theft system) u put one of those in and it wont start. best bet is to get a custom prom for your motor.

not sure about the ESC or w/e.... i believe u just have to change the injectors and chip over to a run a 350 in a 305's place
