He said it was an aftermarket 340 block. And it was either a 4.125" or 4.25" stroke. He came up with a couple of numbers for the stroke trying to say it right so now I don't remember for sure. Only other info I remember is he had Indy cylinder heads on it and a Dominator.
He also said he blew up several rear axles over time and gave up and just put a Dana in it. Had a picture of that peaking out from under the back bumper...:BangHead:
Looked like a four link, too? Didn't stick my head under to verify though.
