Hi i have an 89 iroc, It is currently 350 auto. when i bought the car it came with an 86 rs parts car with a 305, five speed and a borg warner rear end. The engine is very mildly dressed should i swap drive trains or wait tell i can afford a TKO
Thanks Dave

 

The 5 speed will probably not last if you beat on it. They were only offered with the 305 engine because they wouldn't hold up to a stock 350.
