Muncie M-21 question
Is the Muncie M-21 from a 69 the same as for a 72 LT-1? I have one from a 69 that I was going to swap into my 72 and the output shaft on my 72 is larger. Is this normal or has there been some changing of output shaft on one of them?

The turbo 350 yokes are common.

The '69 Muncie will have a smaller dia. output shaft as you describe. I believe the change to the larger shaft was made in 1971.
