I resize when I upgrade rod bolts in the Fords, but only for that. For a stockish build it's not required if the rods check out as the bolts are reusable. I think that's normal with the usual old Ford stuff. I've never researched a modular engine.

I just ordered new Datsun bolts and nuts. When they get here I can gather my stuff and get it to the machine shop for the cleaning and the magnufluxing and the boring and the turning and the balancing etc.

I'm concerned about getting the compression ratio centered about 9.5:1, so the final decking of the block and surfacing of the head will be done after I mock up the crank and a couple of rod/pistons to check the deck clearance. A sample chamber in the H89 head measures 31ccs. The dish in one of the ITM pistons measures 12ccs. No question here just laying out the plan for the shortblock.

Got cartridge rolls coming in the mail so I can work on the ports. This build is finally rolling!
