396/400 differences?
Why is a 396 a BB. But a 400 is a SB?

396 BB is a big block about 125 pound heavier and bigger.
4.096" Bore x 3.76" stroke
can be bored to 4.196 (That I know of) and should be able to fit a 4" stroke crank for a 454. (442.5ci BB)
400SB is lighter, but more likely to over heat.
4.125" B x 3.75" stroke.
can be bored to 4.165" x 3.75" stroke. (409ci SB)
you can rebore a 400SB 3 times 020,030,040
you can rebore a 396BB 6 times 020, 030, 040, 060, 070, 100had a rebuilt 355SB chevy

well I decided to do another mod to gain max travel of bars past the intended travel points just for that peace of mind. 1/8 inch is to close so now I'll have 1/2" or better. I cut a 3/16" wall...
