New guy with a Firewall Question

Thanks everyone

Can't remember for sure but doesn't fenderwells bolt into firewall somewhere? AND I guess the answer would be "is it stock".

Josh,
I have had several cars where I screwed a plate to the firewall to plug the heater core hole. Has never been a problem. You have gone a little farther. I would send this picture to your Division office for their opinion. If you don't get the answer you want go to the National office. Ray

Terry I see a drivers side fender to firewall bolt and a passenger side fender to firewall bolt. I also see a drivers side vertical bolt fender to cowl panel and a passenger side vertical bolt fender to cowl panel.

I would suggest you get it cleared with the Tech Department.
The rule book reads as follows:

FIREWALL
Alterations prohibited unless expressly permitted in this section.
Firewall coverings prohibited. Where heater/air conditioning
units have been removed, area must be covered with minimum
.024-inch steel or .032-inch aluminum, including rear hood seal/
flange, as on GM A-body. Minor firewall modifications permitted
to C5 and C6 Corvettes for transmission installation. Roll cage
tubing may run across top or side of inner fender well/strut
tower and attach to frame horn. See General Regulations 7:4.

General Regulations:

7:4 FIREWALL
Each car in competition must be equipped with a minimum
.032-inch aluminum or .024-inch steel firewall, extending
from side to side of the body and from the top of the engine
compartment’s upper seal (hood, cowl, or deck) to the bottom
of the floor and/or belly pan. Firewall must provide a bulkhead
between the engine and/or fuel tank and driver compartment.
All holes in firewall must be sealed with aluminum or steel. In
certain instances, fiberglass, carbon fiber, or other composites
may be used. See Class Requirements or consult
NHRA. Use of magnesium prohibited.

Thanks guys. I was building this car for some small tire class stuff. Planned to Mini Tub it and all that. Can't bring myself to Cut this car up.

The whole small tire grudge game has gotten a little out of reach for my 496ci BBC I built.

Decided to look at Stock Eliminator. I have been interested in this class for a long time.

I am not above putting in a firewall half to be compliant with the rules. I will email the Divisional office and see what they have to say.
