will a Slant 6 hurst four speed from my 64 work behind a 360

hi, it will bolt right up to a bellhousing for a 318 /360. you will need throw out fork and pivot for a small block bellhousing. trans mount is in same place.
I assume you have the old ball and trunion rear u-joint on the trans? they will work for street driving and some aggressive driving. the gear ratios are 3.09, 1.92, 1.40 same strength as a regular 833 trans. just food for thought.
