8 bolt small block crankshaft

Actually, I think this may be an old Direct Connection race crank as they were sold over the counter. the 905 casting number was mentioned in the old mopar performance book (BY Larry Schreib and Larry Atherton). The info is kinda vague. All it says is something about the 905 "Good guy" crank and that Petty enterprises was making a copy of the "factory crank" only with a longer stroke. It is indeed a "P" part and is listed in the book as a 340 forged crank with 8 bolt flange.
