I am building a 540ci 14.2:1 compression BBC with Brodix CNC BB-1 head 119cc chamber. Solid roller Comp cam w/ Adv. 285 / 295 Duration .656 & .640 lift due to 1.75:1 roller rockers. 950HP Holley Brodix Single plane intake. I am trying to spin this at 6,500 - 6,800 RPM. This is running a Berkley 12JB-A Jet. I need some advice on the pump. I am thinking of upgrading to a 12JG-A. This will be a lake blaster boat but the occasional prompt-to run with the local guy on the lake with a bigger mouth than a boat motor that I would sure like swamp his boat with my roost. All advice is welcome.
