I have the MS 876P bearings and the info says they are narrow for clearance on all aftermarket cranks. Mick

IMO no reason NOT to go 4.25", with a 6.535" (BBC +.500") you can use the same 1.32" CH piston they make for any 451 B low deck 6.76" rod combo, everybody makes that piston. a 4.25" with 2.200 journals has BETTER block clearance than a 4.15" stroke with the B/RB mopar journals.
FWIW....the 4.15" stroke came about because it mathematically allowed any RB owner to bump to 493 cubes by boring to 4.342" reusing his 6.76" rods and using an off-the-shelf 400B piston.

The 4.15 piston is only 468g though.

How much block grinding for rod clearances was needed with that stroke? I haven't ran a 4.375 stroke in a 400 yet, much less a 4.500 Thanks in adavnce for the answers

The 4.15 piston is only 468g though. Are you using the Mahle pistons?
