One other thing..Looking at your original post (davepl) I see you do list the 0.4" thicker flywheel paired with the 6036, which makes sense given that I only measured a 1/8" difference. The confusing thing is that there is a HOTROD network article about this (and confirmation from Holley who owns Quicktime) stating that the 6036 was shorter and implied it would work with a stock LS flywheel.

l already bought a stock LS flywheel and need to decide if I should return it and get the 0.4" thicker one or keep it. Any experience out there would be appreciated. Thanks!
