Oil pan height to frame

[Jim1855]

I have an oil pan question.

I have the Canton 15-680 Front Sump RR pan. It's 8" deep. When I did a preliminary engine install in the Challenge Car (just starting the build) the pan is about 3/8" below the frame using FFR provided engine mounts and the air cleaner mounting surface of the carb is about 1.5" below the inside of the hood, not much wiggle room. No intention to change pans as the options for one that fits over the 4-bolt front and rear caps is limited.

On my previous cars, the pan was about 1/2" maybe more below the frame. Never had any problems in many miles.

Short of the obvious "big rock" in the middle of the road where's the problem? I'm really not trying to be difficult but curious as to what's been experienced or would be expected. Are there legal or registration issues? This is an area of concern that I've not previously encountered.
