Firewalls For Chevy V8 Big block. 4 inch set back. Will ship direct from supplier - Ships within 5-7 business days. These references are to help you decide which firewall kit will best fit your particular application. There are many factors which will affect your choice of kits; engine set back, radiator core thickness, air conditioning or super chargers. You need to determine the length of the engine package you intend to install and then figure out the distance you have from the back of the radiator core to the stock or existing firewall. By doing this you will know how much extra room or set back you will need. The firewall only fits in one place in the body but your engine can be moved forward or backward as much as needed to obtain proper clearance. Note: These firewalls are designed for the most popular engine-transmission conversion which is a Chevy engine and GMC turbo transmission. Any other engine installation (Ford, Mopar, etc.) may require rework of the bell housing area of the firewall.

This part fits most 1940 Chevrolet Cars; exceptions may apply. Please read the complete description to see if this part fits your specific vehicle and application.
