If I were building this motor, I'd focus a little more attention on the bottom half. Building this much horsepower on what amounts to a bone stock bottom end seems to be a questionable plan. Stock main caps are okay, but main studs are an absolute must, and the 40 year old LY rods are on a suicide mission, no matter what bolts are in them, at this performance goal level.

My opinion is that once your talking about Victor heads, 4500 carbs, and 10-second timeslips, You should have already accepted the costs of quality aftermarket rods, main-studs with a mainline hone; and aftermarket caps and a girdle assembly and should not be out of the question. The fastest way to blow a budget is to put a window in the block.
