I am a drag racer only and looked on the MMM site and see that a drag modification costs $250. Don't get me wrong as I don't know what all that $250 entails BUT as long as I have been drag racing, I have never seen anbody use a dedicated Murnan "DRAG" modded engine. Sure there are guys that run on-road Murnan modded engines but no "DRAG" ones and for me to spend $250, does anybody have some track data on the drag modded engines? No matter the engine size as I have enough data to compare somewhat to comparable engine sizes. That's just a whole lotta cash to gamble with.
