4.25" bore by 3.75" stroke or 4.185" bore by 3.48" stroke?
427 or 383 (not a stroker) motor?
SB Dart Little M block for reference.
probably have to use titanium rods to keep the 3.75" stroke motor internally balanced. Or maybe not, don't know yet.
Cooling would seem to be the largest concern with the longer stroke motor.
Mulling possibilites.

Doug I dont' think 3.75 is "a Lot" of stroke. Especially if your going to buy a aftermarket block. Titanium rods would cost a fortune. I'm sure there are already lots of exelent bore X stroke combos out there. 3.75 is just the 400/383 stroke. You could get big block cid with that much bore and stroke. A friend has a 383 which is the 350 with 3.75 stroke and 6" rods. People who want a quick rev'er build a destroked 400 and call it a 377. The large bore, enhances breathing.
