I just bought a LQ4 6.0L out of a 2000 pickup and I am going to be doing a LS swap into my 67 Buick GS. Right know I am running a 400 small block with a T-56. I just have a couple question for you guys. Will any LS flywheel bolt on to the LQ4? Also will a small block bell housing bolt up to a LS?

 

A smallblock bell will bolt to an lq4, but one hole is not present on the lq4 block.

There is a flywheel issue on early (99-01???) lq4 cranks, so any ls1 flywheel will not bolt right up to the earlier lq4's

 

Thanks for the info.

 

If you have an iron headed motor than there is an extra length to the crank that ***** things up, if your motor is an aluminum head LQ4 than there may still be a spacer but it's removable
