Think the rear end would handle the additional torque, really heavy duty. Had thought about a 292, had a 64 mechanic truck with a 292. Could probably get some pretty impressive torque out of it. Not familiar with that trans, will look in to it. Fabrication not a problem, love that stuff.
From what I understand at this point, the 453 detroit needs multi speed transmissions because of the narrow power band. Is that correct?
