273 build ?????

I've been talking to Bobby @ BJR Racing (I hope he doesn't mind me quoting him) LOL Allthough his supplier can't come up with pistons for the 273, Phil at Flatlander Racing has pistons available in any bore size and compression ratio. Allthough I haven't contacted them, Egge Machine has them listed in low and high compression an a selection of bore sizes. The Egge pistons are cast and not forged but I understand the factory HP pistons were cast. I'm sure cast pistons would work just fine for a street motor. Bobby recommended stock intake valve but a 1.60 exhaust valve, bowl blend and gasket matching the intake and exhaust ports. 480-520 lift cam, 228-236 duration @.050 110-112c/l
Bobby has been a great help. Pump gas friendly 9-9 1/2:1 compression would be good for 300 hp or so. toolmanmike
