Just starting to kick around ideas for my future 409 build. Starting with a truck block. Probably will clean up at .030" over. I will use either a set of 333s that have 2.19 / 1.7 valves or my Edelbrocks. Crank wise, my machine shop may have a good, abandoned 396/427 steel crank or a friend has one also. I checked yesterday and see that Show Cars has pistons for the 3.76" stroke. These cranks would be had for not much over what it will cost to cut the mains down. Intended use is street driving and the hopes of someday taking a blast down a dragstrip(maybe). It will be going into my 63 BelAir with fiberglass front end and a four speed.(if I ever get it done after all my other projects). My main question is, is it worth using the 396/427 crank? The price would be right!
