360 & 390 engine differences
To be more specific, the 360 and 390 have the same bore, at 4.05 "
The 360 stroke is 3.5" and the 390 has a 3.78" stroke.
You can use the same block, and a 428 crank (3.98" stroke) to build a 410 as well.
In general, more stroke results in more Torque at lower RPMs for these motors.
