305 350 swap help
I did read the forum, but i am still sort of confused.
My car is a 1990 camaro rs and it had a 350 from a 94 silverado dropped into it. my car is a manual transmition [5spd] and i dont know if the prom is transmition specific. I dont want to mess anything up so i am asking. It still has the stock 305 ecm and i dont completely understand if i need a whole new ecm for a 350 or if i can just keep this stock one. any help is appreciated greatly.

There is transmission-specific tuning in the PROM.
You don't need a whole new computer, but your PROM should be tuned to your current configuration.
