Aluminum is not the best way to go if you are truly trying to build an all out pedal to the metal max HP deal, look at Pro Stock and Comp and see what they use. Having said that I am willing to give up the 20HP+- I could be loosing by using aluminum for the sake of less weight, and repairability. My junk is aluminum and made 2+hp per cube.





I am so curious as to why everyone thinks that iron is so unrepairable.
Beautiful car by the way
