Fordged 318-3 truck crank or Poly crank, need help ID

The Poly crank and the 318-3 crank will interchange without issue in the block. Your only possible problem area is the pilot hole size & depth. The 8 bolt flange is odd to get but not hard to get a flywheel for. Just look in the "Racing" sections when looking for parts. Your more likely to find it there first than in the stock/OE sections.

You got a good deal.

I found some factory looking eight bolt flexplates at Jegs. Those should work shouldnt they? Also, the pilot could be modified for the pilot snout of a standard torque converter, correct?

I plan on using a 2300-2800 convertor on this crank. I would think the crank could be made to fit the normal six bolt stuff and just use the eight bolt flywheel or flexplates?

Complete plans with this crank is to first run a 904 in the car, then later down the road convert it to a five speed with a keisler/tremec transmission setup.
