Denny,at 71 yrs. of age I havent grown out of the speed thing. I have my trucks running just the way I like them.However they are treated very good,and I drive them very carefully. Then there are the times when some young punk pulls up beside me at a traffic light and revs up that POS 4 cyl car with a tin can muffler on it and wants to race when the light changes. I always have fun leaving them sitting in the dust.Nothing like a nice well tuned V/8 exiting thru headers and a nice set of Flowmasters,and moving on down the road.I dont see that ever changing with me.
