Adding 22 cubes,,, power increase? 528 to 550

With methanol, adding stroke is the best way to pick up torque by taking advantage of the extended burn time. Was your cam ground custom ground for your present combination? If not, it would be best to have it reground for your new combination. Rod ratio change will change where the opening and closing events need to happen at to get the most out of methanol. But really, wow, what a combination! I don’t remember the exact hp & torque/cubic inch numbers that you should be making in a N/A combination with methanol but when brought to its full potential and multiplied by the extra 22 inches it’s going to be a significant number.
