Why not a 413 ?

Well yes, but I’m saying that if someone had one laying around and wanted to rebuild it and use it, using cast pistons for a mild build, it can be done for not much more is all.
Dude i beat the snot out of this 413 with cast pistons! Sometimes shifting at 6grand, i took it from Racine Wisconsin to lacrosse Wisconsin and back sometimes hitting 80-85 mph humming away not one issue.
