This wicked 1971 Pontiac Firebird is wearing a deep blue flame job, but the owner felt it needed more fire under the hood. He sent the car, a T56 5-speed transmission, and a fresh E-85 burning 468 cube Pontiac stroker to the V8 Speed & Resto Shop to install to fix all that. The new mill runs at 11.4:1 compression thanks to the alcohol in E-85, which is the best fuel the owner can get in his neighborhood.

This project came into our shop already wearing a flamed paint job that the owner did not want to change. However, he did want to improve the performance and the level of detail under the hood. The owner supplied a 468 in.³ Pontiac V8 that we were to install, and retrofit the fuel system to operate on E 85 fuel.



The crew wrapped to the entire vehicle in 3M protective adhesive backed to paper so they would not damage the paint.

They removed the front wheels, drained all the fluids, and disconnected the wiring. Then, they removed the entire front clip of the vehicle in essentially one piece so that they had better access to the engine, firewall, and subframe.






 
Once we remove the front sheet metal, it was obvious that the firewall needed help. It was green in color, and was a complete mess.

Under the car, the crew removed the original fuel lines in preparation for the oversized lines required by the E85 conversion.

Next, they removed the front subframe, and stripped the paint from the firewall. After some minor bodywork, the firewall was seam sealed and coated with satin black paint.

The subframe was media blasted and inspected.



The main welds were reinforced, and the front sway bar holes were drilled out and grade 8 nuts were TIG welded in place. This repaired the stripped out holes in the frame and added a much stronger attachment point for the sway bar mount.
