Does anyone know the effective dome volume of the H345P sealed pwr piston? My Dad had his 350 machined back in 1994 and I'm starting to put it together for my Nova. Trying to figure out the CR, and they don't make the piston anymore. Any help would be appreciated.

I hope it's 5. That's be better than 6.9 I see for the current H345DCP piston. Thanks for the response!

I think this would be ideal with my Holley Systemax aluminum heads.

I can't read the pdf after I put it there. Basically with 5cc Eff dome vol, 4.030 bore/3.48 stroke, 68 cc heads (aluminum) and piston 0.020 below the deck and a 0.016 head gasket I'm at 10:1 and with around 0.035 quench. As long as I have valve clearance I think this will make a nice pump gas street motor. I have a advertised 284/288 deg duration Schneider Hyd cam with 108 LSA, an Edelbrock Air gap intake, Holley 750 DP, and Hooker Super Comp long tube headers. Muncie 4 speed, 3.90 gear, and a 26 inch tall tire. I may go to a 3.25 gear.
