I just did all this with my 71 Demon (stroker small block stick car which will soon be in the 600HP range). I went with a new Strange Dana 60, Caltracs bars with thier Mono leaf and 9 way adjustable shocks, etc. I also added a new Passon OD trans, drive shaft, new clutch, and a Lakewood bell housing. So far I'm happy

*The worst part of the swap? Installing the POS Lakewood Scatter shield.
