Thank You for the great information.
In the process of looking for a 4.3l V6 motor mount swap like the hooker one I came across this information.
"
Chevy 90 degree V6: This block can either be the 3.8 (229) or 4.3 V6. These engines are identical to the Chevy V8 application with reference to bellhousing, starter, and flywheel. The oil pan has year differences like the Chevy V8 except with the 1997 & newer aluminum oil pan. Vehicles requiring oil pan modifications should not use this block. Motor mounts are also the same as the Chevy V8 with the exception of the location of the triangular bolt pattern in reference to the back of the block. The mount is approximately 4-1/2² closer to the backside of the block."

So it answered the question and I didnt have to get dirty this time. So I will say that the hooker kit will work with a "CHEVY" V6 swap just not a Buick V6 swap. It talks more about the diffrences on the website.
Just an FYI for anybody considering.
