Do restomod chassis have provisions for the factory splash shields? Would it be an aesthetic choice? I'd assume they would not be needed.

These keep errant underbody air dirt water from coming up getting trapped in that area. Necessary? maybe - especially if you have modules and ebrake stuff in that area
tube chassis dont have mounting for these, the body does, unless you fill the holes - still can be added later before carpet.
I am not at that point to make a decision

Are they splash shields or for aerodynamics? I know of no other GM car that utilizes these closure panels and the C2 was designed to be a competitive car for the race circuit.
Wish John Z where still here to answer that one. Of course there are other knowledgeable members who may chime in.

I wonder about the cooling flow through the radiator
Right now mine are off
but would it help or hinder cooling flow leaving it like that?
Because I have an electric fan, I don't have a shroud covering the gap
behind the radiator bottom
I also have the restriction of an A/C condenser in front of the radiator
Thus I have the air entering the radiator's face with two exit points,
behind the radiator and where the splash shields are
What I wonder if having both of those spaces open would lessen the air flow
through the radiator by allowing it to bypass it,
or will leaving it open actually help?
Air flow can be counterintuitive and low pressure spots can develop that
cause the air to flow in the opposite direction you expect
I remember driving a convertible in the rain and the rain splattered the inside
of the windshield. LOL

My thought is the "splash shields" are actually helping trap heat in the engine bay. Minimizing the square feet of ventilation area for hot air to escape also reduces the cfm of air passing into the engine bay for cooling. Even with air, you can only put so much in without allowing so much out, like your tires.
I had a V-8 Vega and the engine compartment was so tight I had to open the hood a couple of inches to allow the air a path to flow thru or it would overheat with the biggest radiator I could stuff in it. With the hood gapped open, it would run under 200F.
Just my $.02

I left mine off. I don’t intend to drive it when it is raining or dusty.

I have mine off also. Car runs a cool 165 deg. with twin fans and a DeWitt's radiator. 427 with cast iron exhaust manifolds. Cars interior never gets unbearable. I am not going to put them on to find out if it heats up.....LOL. Fred

Since these cars were made to be driven in all kinds of weather and roads, and yes even (shudder) gravel roads I would guess that they were there to keep water, snow slush, and rocks from "splashing" up on the body foot panel (unpleasant noise and feeling) and richocheting up into the engine compartment and possibly spark plugs.
Just a guess from someone that drove his new Corvette as indicated above.

I'm thinking they would restrict the air flow and trap the heat in the engine compartment. I am using a Dewitt duel fan rad with a GM LS3 hopefully I will not have a problem with overheating, but there could be heat transfer into to the cabin with the shields installed.
