I know, you might want to look at some symetricals, the engine would run a little smoother accross the cylinders and make big HP.

I ran the Brodix baby ones, the runners were 388 cc after the CNC porting, they only flowed 455cfm at .700.

I hate to have your gas bill. Are you going with the Jesel lifters?
The one guy does endurance racing with his apache oversees and the rockers on his big chiefs work. 200mi races. |

Big Chief, Big Duke, either one, usually within 3 cfm per runner instead of 20 to 40, you don't need quite as big of a cam and the shaft rockers seem to work pretty well. You can always run E85 like we do.

Just looked it up 100LL is about 6.20 Gallon with lead valves are happy.

I ran the Big Dukes on a Procharged 598 with a solid roller, they seemed to run pretty good. Used to turn it up to 7500rpm at the lake shootouts. I sold the boat about a year ago. We've been running the E85 in my brothers boat for the last 3 years without a problem.
