on the rear of the engine block it has 3970010
and a 36 near the same area.

I have no idea what the fwrd cab refers to.
They list conv cab, van, bus and fwrd cab under the "applications" area.
I would guess it refers to the type of chassis it was delivered with.

I see what your talking about rick but when combined with the number on the front of the engine it would be a 1977. that would eliminate all but the 350. Do you guys know what the 36 would be for? it is located near the rear casting number
