Not sure what the engine was called other than it was a 4.1L six with twin Carters. In the discussion area on the link they mention the engine shown is not correct. Also in the pictures the cross member is intact, unlike the current ebay description, so my guess is this is someones gave up project. I just think in it's current state a small block of whatever flavor fits best and a custom frame would be appropriate, but nothing with stupid horsepower, which seems to be in the current vogue with the tatted up idiots on television. Brookland windscreens would look good.
