I'm currently looking at bolting on a set of AFR 1054's to top this engine off. My plan for this motor is to use it for mud bogging. My dilemma is that I want to bolt on a set of heads that can really match this cam and make this motor push 550 horsepower to really spin all four of the 35 inch mud tires. Rear end is a 3.73 gear and plans to go to 4.56 are coming soon. Any advice to what set of heads, or cam change would be appreciated. I also want to be able to run no higher fuel than 93 octane but if alcohol is needed to raise HP and torque a reasonable enough amount to justify running it then I'm all for it. Thanks in advance.
Keep in mind before you order lifters that the Dart SHP requires .100 taller lifters and that the lifter bores need honed.
