You've come a long way baby!

Off the top, for me would be radials, biggest bang for the buck and a slam duck .08 to a tenth...you need tires anyway; second aluminum drive shaft (for SS....right stockers?) and advancements in oil tech....you need all three anyway and they are stand alone ET enhancers

For class racers, I'm still wondering if the LED bulbs were a help or hinderance (non car item)

Lack of consistent "hook" is the biggest negative (I'm assuming the Pros want wheel speed rather than a dead hook, and Class racers suffer IMHO)

[Rich Aceves]

I agree with radials, and please let's not forget VALVE SPRINGS.

merry Xmas

I agree with Rich, on the valve springs. That would be the first rule I'd change, if I where "King of the World". We'd go back to stock spec valve springs. Pontiac guys must think alike!
