- 1971 Mach 1 restored in the original light pewter metallic with TMI interior and custom stereo from Pacific Car Audio
When we tore down the 351C 2V in our 73 Cougar a few years back we were a bit surprised to find this
The passenger's side exhaust manifold was blocked from the factory. For the first 115k miles of its life this poor thing had to breathe out through the crossover in the intake and out the driver's side manifold. This lead to a cracked head and intake manifold. We were able to find a date code correct head on eBay and we replaced the intake with a Edelbrock Performer 4v. We also changed out to a dual exhaust. Still by no means a performance car, at least she can finally breathe
