I was wondering if it is possible to put a 401 crank in a 360 to make
a "stroker" engine (similar to putting a Chevy 400 crank in a 350)? What
is required beyond the typical rebuild stuff?
Roy, I did this once before on the list and it seems I didn't save the
thing. I will this time :-):

The AMC V-8's thrust bearing is #3. #3 is exactly the same between the
two. The 401's #2 & #4 main bearing widths are the furthest off by 20
thousands. I think it'll work no problem. You'll have to use 401/390 rods,
the corresponding flex plate & damper and custom pistons, though.
The 401 & 390 crank (3.68 & 3.57 stroke respectively) are forged and
the 360/304's are cast. The 401/390 rods are also forged where the 304/360s
are not.
