"This is an excellent choice for more radical race style engines used on the street. It allows for extended highway
driving and has excellent "lock-up" characteristics with higher stall speeds resulting in better ET's at less RPM. Has
good street manners, good idle characteristics in gear, great throttle response and very low heat generation,
custom built."
