Passion Hemi OD

I have one in my 67 dart.
No differences in mounting than a stock 4 sp.
The 3-4 linkage is different then stock but comes with trans.
18 spline clutch is needed.

I run 4.30 gears and 28" tall tire. I cruise like 3.55s.

I debated the 5 speed and also the t56. I did not want to wait for the 5 speed and the t56 swap would of been a bit more $.
