A friend of mine gave me a 7al3 box, in payment for work done. I currently use a 6al. Besides getting rid of the 3 step box and other features offered on this this box, will the engine perform any better? I read about more spark or energy with this box.

The 7al series box should have more power so if you need that is could help. It is not for prolonged use like round track racing or street driving. I've been using the 7al2 boxes for years. The 3 series has a couple more features but is basically the same power. RM
