This will be my first time to the track since high school (1980). I have a 69 elky with a street 540, th400 and 373's. I bought a new set of 10.5x 28x 15 slicks. They use to just check for 5 lug nuts and a break peddle. What will I need to bring besides tools and a spare part or two? I have no clue as to how fast it will run. These are supposed to be the fun drags and I just want to see what kind of number I can post. I have a roll-bar....what else.
Thanks in advance.

Driveshaft loop is going to be required for the slicks. If the Elkie hooks you are probably going to need a helmet :cool:
Radiator overflow catch can is a must.
Double return spring on throttle.
Those are couple of things they check for here when they are running the "fun drags".

battery holddown

If automatic tranny...neutral safety switch(no start in gear).
