Mopowers' 66 Dart Build

Thanks. Frankly, I probably wouldn’t mount the solenoids to the box as it’s supposed to be sealed. It was never raced like that so I can’t say whether it would have passed tech or not. I‘m still using the same battery box so the plan is to plug/cover the holes. Just something to think about, probably be OK either way as long as it’s a sanitary job and does not invite extra scrutiny.

I could be wrong, but I believe the battery only needs to be in a sealed box if you're not running a rear firewall that meets the minimum thickness specs.

That actually brings up another question I need to do some research on. Is there a need to use a sealed battery box vented to outside the car if using a firewall? I vaguely remember reading that there's a potential for corrosion issues in the trunk area if you leave the battery open. Is there any truth to that statement?? I'd imagine if you're using a sealed battery like an Optima, it's a moot point.
