Just a data point...your block should be a 4 bolt, so you have a good foundation. Couple that with some decent heads and you're all set. The stock rotating assembly will last all day at 6000 rpm or a bit over. If you want to spin it tighter than that, the insurance the forged parts provide is a good idea. You can make some serious power without exceeding 6000, though....just a thought.

I look forward to the next steps in building this block. Now that I have made the decision to get the crate engine, options for the old block are wide open. I will be checking with the local schools to see about getting the machine work done.
I still have to measure things up and see what I have before deciding the build path, but I am thinking about a configuration that's somewhat rare: a mid-torque, high-revving, over-square 377, with a centrifugal supercharger to spin 8-9k. I would really rather do this with an LSx, as the target vehicle will be something on the light side (thinking stripped down, street legal, Gen-II Firebird set up for serious road racing). Not sure yet. Maybe trade/sell some of these parts for an LSx. Thanks again for your comments.
