I'll go first. My brother and I started racing in 75. Had CMS do the machine work on our first motor. They were one of the hot places at that time and we read about a big block Chevy Stocker they built that set a record. For those that are not old enough Danny and Wayne Jessel owned CMS. As dumb as we were back then about Stockers, we really didn't get much from them. Not long after that they had their share of troubles and went out of the machine shop business and started Jessel valve train products. It took us 2 years to run the index. We were lucky we ended up at a shop that was about 10 miles down the road from us. Precision Auto. Owned by what I still believe to this day were a couple of the smartest guys in the business. Dale Hall (Yes Div one hall of fame and small block chevy Alcohol dragster) and Norm were very helpful and took the time with 2 young guys that had only a small clue. I still remember after banging several valves and thinking they did something wrong. Dale came out to the house and showed us how to measure piston to valve the right way. We put the motor together and just didn't give it enough room. He took the heads replaced the valves and set it back up without charging us. His son Scott Hall has followed in his footsteps and stayed in the automotive industry working for Moroso.

How many could still set up a dual point distributer to change the timing as you go down the track? Remember those days.
So here is a tid bit that I'm sure most know. If you run an older small block chevy Stocker auto. Make a pass. Come back and change your timing to at least 42. Make another pass. What did your 60ft times do? Now figure how to get it back to normal timing before the 60ft. Top end after the shift you should retard about .03. Play with it to see what your car likes. As we know every car is different. Your gain will be more in the summertime. I think most of you are playing with timing but if you don't you are missing out on about .04 Thats one of the reasons why I like the digital MSD boxes. Who's Next ! BP
