This pic shows the mild firewall modifications we had to make. In order to make clearance for the valve cover, we had to push the firewall back about 2 inches. I glued it all back together with JB Weld (about 40 dollars worth!). We also had to push the firewall back about an inch to make clearence for the exhaust manifold.
I knew from the beginning that there would be no A/C, but I didnt know I would have to tear out the A/C condensor to fit the engine. As it turns out, when the heater is on, the hot air passes by the condensor into the dash. I wanted to keep heat, so I had to fab that blue triangle you see to get the hot air into the dash.
