The Pinto/crossflow bolt configuration is the same on both blocks but I don't think it's the same on the V ford engines ? One thing it is a cable clutch operated housing so it could be for a Cortina Savage ? I know that the old 3 rail Tina box wouldn't put up with that amount of torque but was one made ? Probably Joe might know ? The trouble is Pete that most people that used this stuff in period are getting on a bit or not here at all !! and I being almost mid 70 forget what most of this old stuff is in my own workshop as well so you're not alone
