I want to make as much power as I can with my indy 440-1 hand ported heads. They flow 356 at 700 and around 370 at 800. I know I wont make what you guys with B-1 Mc are making. But I want to build a good foundation and make a strong reliable bracket engine. My goal is to make 900hp with my heads. I can always upgrade my heads later. I don't have the budget for new heads right now. I already had a 499 ci and will be reusing my heads and pushrods, lifter. My car is a 69 road runner that weighs 2947 with the 499 ready to race with me in it. Chassis is ladder bar in the back and struts in the front. The suspension can take the 900 hp goal.
