I see a lot of parts that will fit ls1's or lt1's.
what is interchangable with the lq4's?

The reason I ask is because I want to put an lq4 into my T/A but I only see things for ls1's and what not (headers, motor mounts, etc etc)

 

Block dimensions are the same between the LS1 and LQ4. Heads, cams, bolt on's, accessories will all interchange for the most part. However, the LT1 and LS parts don't go together.

Yhe LQ4 is an iron block 6.0L, its the lower compression 6.0 L truck engine. The LQ4 is interchangable with a LS1. Probably only bellhousing and motor mount locations are the same on an LT1.
