If you are planning on a stock block build go with factory stock bore piston. With the OP's weight and desired power level, the last thing you want to do is run a 4.125 bore piston and stroke it. 6 liters is plenty to make 1200whp... Factory stroke, factory length rods, and factory bore will result in the strongest most reliable rotating assy in a stock block. Even then you aren't going to be what I'd consider reliable.

This is a 370 that was split around the op's desired HP levels and only 3300ish lbs. Add a ton more overbore and additional side loading from more stroke and you just weaken it even more. Don't buy into vendor BS trying to upsell you a large cube engine if you run a stock block.

Reliable combo, 5.3 (lots of bore material, more stable), 3/4" deck heads (more flow/more stable, less boost required), 1/2 studs (more consistent/stable clamping force) Spec rotating and valve train assembly to spin 8K which gets you the air flow of a 6.0 at 7K. Tune to keep it alive for many runs.

Capizzi is setting the mark with SBE 5.3. With better rotating assembly, you should be good for a few seasons before tear down and inspection.

Yep, 35+ on thin stock deck 799 heads. Amazing they hold. The magic is in the tune and rpm. I'd estimate 1200whp at 28 - 30ish with aftermarket heads.
