I am going to be eventually putting a 350 TPI in 305 TBI if i end up getting the car. What i am wondering is what is different in the TPI harnesses from i think it was 1987-89 and 1990-92? How easy is the swap? and besides the harness and the ECM what else would i have to get from a donor car to complete the swap? thanks

id rather buy some aluminum l98 heads and a lt1 cam , edelbrock intake man and some shorties for the price of the swap. keep the 305 tbi

but if you really wanted to, there isnt much difference in harness's but you would need a tpi harness/ecm, no doubt......
