Many of the things mentioned here have made many of the old Musclecars 2 seconds quicker than when I first raced Stock.

For the engine, the unlimited cam duration & spring pressures have obviously allowed much higher rpm & hp. The approved forged pistons & rods, & even aftermarket blocks, have allowed many engine combos to run 8000 rpm plus, & live. Don't know how many of the longer stroke engines could do that back in the old days.

The lighter legal auto trans have also lowered ET's some.

I also agree that the Cal Trac type bars have made the leaf spring cars quicker. Many of the 10 sec Stockers now need wheelie bars to help control the launch. So, when you know you're hooked to the track, you can then obviously make other changes that will lower ET.

I'm obviously no expert. These are just casual observations, comparing what I saw in the '70's, to what I see today.
