350 4bolt main and 700 r4 $600
I have a 350 4 bolt main motor (jasper rebuild?) complete from carb to pan. It is bolted to a 700r4 trans which has a b&m shift kit.
Motor and trans are still in car so you can see it run and drive if you are interested.
Engine has an oil leak at either the mechanical fuel pump, front crank seal, or timing cover. Seems to be in great shape otherwise.
roughly 80k miles on both.
will consider separating
will NOT consider shipping.
600 obo

I will take 400 for just the motor, 350 if I keep the distributor, carb, plug wires, and accessorys.

the casting on the back of the block is 3970010. should be a 2 peice rear main. Mortec.com says 69-80. This was also the casting used for the dz 302 in the 1969 z28.
