Hey guys, I have a few questions. I am in the beginning stages of restoring my car and I have come to a crossroad. I am not restoring the car to original specs and I had the original engine torn down, 2 cylinders trashed so there goes that block. I don’t want to sleeve the block since it wouldn’t be worth it. Now since the engine wont be original and the car wont be stock spec I am considering selling the transmission. It is a 1966 18spline 4-speed with Lakewood bell housing. The question is, is before I decide to sell it how much can a 23 spline 4-speed handle? I don’t plan to sale the car and the purpose of this car will be cruise ins and the occasional burn out, I DO NOT intend on racing it at all but I don’t want to hit it and have the tranny explode on me. The engine I want to build will be a warm 440 hopefully shooting around 425hp. Let me know what you think.
