Life had a different direction for me for the last 10 years. But now I'm at a spot that I'm considering racing again. My thoughts are either going back racing in Stock OR make it a Drag and Drive car. The car has been sitting untouched for years. Obviously, everything that is there will need to be freshened or replaced.

Just some of the questions I have:
1) What major rules have changed over the last 10 years?
2) What can or what should be updated to be competitive based on rule changes over the last 10 years?
3) Are things like digital ignitions & data acquisition a must even on an old school carbureted stocker?

1.The solid lifter rule, and the lack of tech inspection. Not sure if solids will help your combination much. Probably be a small gain. Not necessarily worth it unless you need a camshaft. Camshafts and lifters have become an issue, the cast cores are getting hard to find, lifters are expensive and can be a problem. Playing with camshafts and lifters can be expensive and difficult. Few cam companies even care that you exist if you run anything flat tappet.



2. For performance in the engine, you can look at rings, hone finish, valve job and valves. There is definitely power to be found in the latest in rings and hone finishes, so if you need to freshen it up, that's a place to invest. Guys like Keith Jones at Total Seal will help you there. There might be some stuff in your transmission, depending on what it is, and how up to date it was then.


3 Digital ignition probably will not help you much, if any. If you're already running a good MSD 6Al or 7AL-3, you're not going to see much of anything in the ignition. To be honest, there are some relatively inexpensive data acquisition systems you can buy affordably that will help you tune your combination and see where it can improve, and often those improvements will help consistency.You do need a really good weather station. There's no electronic substitute for knowing your car and the weather to predict the ET. But with a good weather station (Kestrel), an inexpensive data acquisition system (really, just two A/F ration sensors, an RPM input and a driveshaft RPM sensor is enough, Daytona Sensor had a good setup) and the willingness to put every single factor and data input into an Excel spreadsheet you can absolutely predict your ET well enough to win.
