CNC dude, thanks for the info on the Ross pistons earlier! Lurker Dave here; This settles it for me--I'm thinking a 292 bored .060 over, stock rods, ross pistons, water heated intake with a 390 holley (I already have that; tho the megasquirt looks nice) to replace the 250 I've got now. (currently set up with headers, clifford intake and 390 holley)...still have the stock head, so that is the first priority.
