I have used that system on oval track engines with good results, but I cannot imagine it working well on the street. With the Hooker long tube headers, free breathing exhaust and Accel ignition kit, I have increased my fuel economy to around 17 mpg from 12.5 and notice an impressive increase in torque. I am thinking of roller rockers, but don't really expect dramatic results. From here on out the law of diminishing returns kicks in and each small gain will not be justified by the dollars spent. That's when it becomes this guy thing of upgrading a part for the cool factor.
How long did you have the Accel ignition, what mpg gain did you get and how did you measure your mpg?
I'm interested both the ignition and long tube headers so this thread is great. I'd like to hear more.
