It had two 5 gallon cells with two BG400 pumps. I was afraid the neat single reg wouldn't work, cause it was gonna be too clean of an install and allow just a single gas pressure gauge.

Can someone point me to a log to mount two BG regulators?

The cam is a regrind of the huge cam that came with the motor. Now a Lunati http://www.lunatipower.com/Product.aspx?id=1556&gid=370 cut on a 114 LSA with 1.7 rockers. Hard to find cam blanks for the 48* raised cam on this motor.
