Not Ranked
What air cleaner were you running on the 2 fours when you dyno'd it? If its those little chrome things one for each carb..then I know where some of the power went.
On my ERA I gained over 40 lb of torque from just changing to the stainless pipes with less restrictive mufflers...and 18-20% loss would be about right...Again if you have those 2 chrome air cleaners on the carbs those will suck the life out of a motor because it can't get enough air!
