1999 Dodge Durago Headers - Heavy Metal Mudder Phase II

The fundamentals of fabrication revolve heavily around time and patience. While some have the natural knack for fab work, for others it's a skill that takes years to develop and perfect. When tackling a project as big as our Viper-powered Durango, it was important to equip ourselves not only with the right tools but the right professionals too.

Working with the crew at National Speed in Wilmington, North Carolina, we spent last month fitting the 505ci engine into our Monster Mudder and began forming the custom dog-box firewall. Now it was time for the headers. Since space in both the engine bay and firewall is limited, we pulled the 8.3L out and headed to Momentum Performance to build the headers. We relied on Momentum's fabrication experience with performance headers to build us a set that will allow all 500-plus horses to exhale freely.

In addition to the headers, we used our time at Momentum to finish up the custom firewall. With the engine now resting nearly a foot past the original firewall location we needed a few access ports built into the dog box to service the back half of the engine. Though we looked at making the unit completely removable, we were concerned about how feasible it would be to take it out of the vehicle once the dash was in. The other issue was sealing the firewall to keep out the elements. In the end we opted to weld it in place.

Be sure to check us out next month as we continue to hammer away on our Durango and move forward with the remainder of our monster Mopar powertrain.

What's Cooking?
Talk about the ultimate manifold burrito access port! With our dog-box firewall set in place, we still have a laundry list of items to cover. Be sure to check back next month to see if we found a place for our accelerator pedal and to see us start on the bulletproof drivetrain that has to handle the V-10's grunt.
