i heard some old machinest at the track the other day rant about a chevy 351 stroker.. i butted in and asked about it.. he said its a 305 with the crank from a 400 but thats all he said no explination on rods over sizes ect. ... anyone ever heard or done this stroke???

It would be a standard bore 305 with a 4" stroke, not a 3.75" 400 stroke.

Either way it'd be a pointless waste of money.
