I am building a 520 RB with cnc'd max wedge victors purchased from MCH. The cam i have in mind is comp xr292r. This will be pump gas half street half track engine.I am thinking of the 440-2 single plane. I am hopeing for 650 to 700 hp. Any advice from all would be great. Also has anyone tried the super victor. will it be practical on the street with the 4500 flange. I am new to this so.....
