It won't fit


I think it would fit, things to check out first tho, Andrew, why do you think it would not fit?


A trailblazer 4.2 in an inline 6 with a different bellhousing and entirely different motor than the 4.3 v6


Thank you, did not know that, good answer. The bell housing would be a problem.
