I started this project years ago and finally have time to get back to it. Of course over time my goals have changed and now Im not sure the block can handle it.

It is a stock 70's four bolt main block. It is .040 over. Decked to zero. Had it line bored, lifter bore honed, and a few other misc. things done to it. It has main studs, Forged crank, forged H-beam rods, Forged pistons. Everything was balanced.

The bottom end should hold to around 1300hp. I am adding a F1R procharger. The bottom end should hold up provided my block doesnt let loose. I am planning on just a tad bit over 1000hp. It will be a high comp, high boost, alcohol motor.

Had I not dropped 2k in the machine work I would just pitch the block and start over with a Dart Iron Eagle and swap internals. I hate totally wasting money, but **** happens when it comes to building fast toys.

So what are your thoughts. Will a stock block handle it? Can you modify it to hold up? Planning on reving to around 6500rpm.

 

A stock block holding together at 1000+ HP? I seriously doubt it. I have a friend with a blow-through turbo motor that we're sneaking up on 600 and biting our nails wondering when it's going to let go. We've got pretty much everything you've got plus better main caps and a short-fill.
