Trunk mounted battery

[x33rs]

I seem to remember NHRA didn't implement the cutoff switch rule right away when batteries were relocated. I think that rule came later. So in my eyes I'm thinking like Bentley and would tend to believe it's not technically a "day 2" mod. More like a late 70's mod out of necessity if you want to hit the track with a battery in the trunk.

I'd bet someone here remembers when that rule was implemented.

We ran our GTO up through 1974 without a battery cutoff switch (still doesn't have one).

The car was delivered new with the battery already mounted in the truck (the battery was sitting on a re-purposed production battery tray).

Thanks Keith,
My guess was late 70's when that rule came into play from what I remember. So at least with your information we can safely say it wasn't in affect up through at least 1974.
