Its about 2.87" from fingers to TOB face. I am using the 1364 Mcleod HTOB with the correct piston (after a few different pistons
). If I recall my measurements, the OEM Ford Bell Housing I have has total height is 6.250" (without the OEM motor plate). I need this shallow depth(height) for chassis clearance.
I am using the short input shaft on my TKO 600.
In looking at the Quick time catalog, they too offer "Universal" bell housings for 460's for different register bore diameters which tells me they too provide these reducer rings ??) But the quicktime RM-8015 appears to have a register bore of 4.685" for the 460 Ford and the depth of 6.30"
