Firewall For Chevy V8 Big block with a 4 inch set back. Will ship direct from supplier - Ships within 5-7 business days. The 1941-48 Chevrolet parts are some of our latest additions to our rapidly expanding line of parts. We feature 2 firewalls; one for small blocks and one for big blocks. The small block firewall has a 2" set back while the big block has a 4" set back. Our firewalls replace the ugly old stock firewalls that are full of those unwanted holes to give you a clean looking part you'll be proud to have in your rod. 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 1941 1942 1946 1947 1948 Chevrolet Cars; exceptions may apply. Please read the complete description to see if this part fits your specific vehicle and application.
