Yea it will, my friend has a 92 rs. we got the iron headed lt1 out of a wrecked buick roadmaster and he found a six speed with all the plumbing for 400 bucks. We paid 150 for the car, then sold the 4l60e for two hundred; So now he has a low 14 second car and 20+ mpg for next to nothing. he wants to run the hot cam but is affraid his springs wont handle it so hes debating between getting his heads machined or just finding some f body heads.
