I am building a 400 "B" to 500 cid stroker, but it will mostly be a bracket engine. The lightweight pistons should make the engine rev really well, but I can see how the short skirt of the piston would rock more than the taller 470 cid stroker piston. I figure this will wear the rings faster, but on the type of engine I am building it might get inspected and freshened up every year or two anyhow.

The 451 Stroker I had, laster 12 years with no problems then the intake valve broke and holed the piston, and nicked up the cylinder, plus made a mess out of the cylinder head in that chamber. otherwise it was a very reliable engine, but give up displacement to the bigger stroker engines.

We just fired up my friends 470 last week. I guess we will see how it performs and lasts..
