    The highest compression I know of someone running is 14.5 to 1

    This is where I found some info when I swithed over. Try a Google search you will find more info.

    That's what the previous owner told me he said between 15.5/16 to 1 , appreciate your feedback, do you have any experience with a T400 with OD by any chance? Thnx again.

    Not really never built a tranny I was happy with tried a couple ford c4s I had a guy build my th350 when my 400 broke. Have you checked into a gear venders OD? From what I understand they work well in high HP and torque applications.
