Need 2.8 and 3100 crank info.

[TheDirtyBen]

my cousin has an 88 chevy blazer 2.8. We were going to take the bottom end internals out of my old 94 3100sfi and put it into his block. Unfortunately, the crank in the 3100 is busted (literally). do the 2.8 and 3100 have the same stroke?

[SappySE107]

nope.

[TheDirtyBen]

ugh!!

The 2.8 is 2.99" stroke (76mm)
The 3.1/3100/3400 use a 3.31" stroke (84mm)
