1969 Camaro Transforms From Big Block to Supercharged LT4 V8 at V8 Speed & Resto Shop

The edges are tapped over with a tee-shaped rounding dolley.



Some shrinking helps tighten up the edges



The main piece seems to fit pretty well. Next, the tunnel portion is marked for an extension piece on the firewall. This will allow more clearance for the LT4.





A trip to the Pullmax starts the tunnel housing extension. A pointed die begins to “fold” a flat section.







The shape is roughed in.

Some shrinking on the Mittler Brothers shrinker helps form the curves



And a bit more on the Pullmax to make the contours deeper.



And the corners are tightened up with a sharp-edged dolley.



A test fit with magnets and cleco clamps, things are looking good!



The section is tack welded to the firewall with the HTP Mig 200 welder, then test fit in the car.

The firewall is cut back a bit to facilitate the install of the new panel.







The welding is completed and metal-finished, then the panel is cleaned and treated with an epoxy primer on the inside.



Any corrosion is removed from the firewall, and weld-through primer is applied before the new panel is welded in place.



The firewall is then welded to the car, and all welds are finished.

This little corner requires a small piece to “connect the dots”.





Welds are all ground and metal finished.



The finished firewall will only require a touch of filler before epoxy and paint.

[V8TV]

The LT4 is lowered back in place, and the fit is verified. It’s still a bit tight, and the harness will need to be held upward during install to fit cleanly in the new panel’s recess.

That looks nice Kevin, As always.

Nice work, so the A/C compressor fits the subframe without modification?
