We talked to an old guy at Indy that said he built a lot of motors for Tony. This has an old school stroker built by Indy. 400 block with an offset ground 440 crank making 470 cubes.
Had an engine combo like that in a 71 Duster in 2000....best I got on a lousy prepped track was 9.95@134 but the guy that bought it from me got it much faster.
