thanks guys, thats quite a list!

I figured the tapered one would be what I end up with. If stock pistons are 4.250 (I think - should measure) & mine are .030 over I assume I need the 4.280 tapered or do you want one slightly larger than the oversized piston?

Oh yeah, going in a 69 383 HP motor, badger 10:1 pistons.

Thx. E
