Yes the main bearings on the 400 are larger. But the big difference in the after market 3.75 stroke crankshaft is they are lighter and the counter weights are smaller so you need less clearenceing. They also can be internally balanced so you can use the 350 dampner. I bought a steel crank with scat 6 in rods and forged pistons for around $1200.
