BB - SB motor mounts ?

Is the mounts on the block the same? Would all I have to change is the frame mounts ? Or all of them ? Going from a big block to small block on a 77 c10 1/2ton.

You wont have to change anything. All the mounts are the same.

I've always used the same upper and lower mounts for either engine.

HAHAHAHAHA I think you're both right. I think the big block mounts are an inch lower but I think they'll fit either way.
