I am working on a 427 that has .140 dome pistons, oval port open chamber heads 113.0cc from a 454 and I am wanting to stay between 9.5:1 & 10:1 compression ratio. Does anyone know if this combination will put me in this range or do I need to go with a taller dome piston?
Thanks

Please go over to the ROSS Racing Piston site and use their compression ratio calculator..
