Trans will bolt up to the block without an issue. The LS engines have a bolt at the top of the point on the bell housing that the SBC doesn't use, and the LQ4 will have a blank spot where there should be a bolt hole on top passenger side. The LQ4 should already have a spacer between the crank and flexplate since it was intended for a 4L80E, which should have the proper pattern and bolt up to the LT style 4L60E.
