One of the most difficult areas to address was the cooling system. The Viper engine was about 8 inches longer than the old Plymouth V8, so what had appeared to be a lot of room turned out to be very tight. Because I live in Phoenix where 115 degrees is common in the summer, I also wanted to get the largest radiator I could fit between the fenders, and have room to mount an AC condenser. I ended up having an aluminum radiator custom made and used a dual fan from a Dodge Durango with a DCC controller.
For an exhaust system I went with SpinTech mufflers and 3" pipes that exit in front of the rear wheels. I was able to fit 275/60x15 Nitto drag radials without cutting, and decided to go with chrome steel wheels for that old school look.
Since I plan on spending a lot of time actually driving this car when finished, I need to have it comfortable as well as reliable. I want all the controls like the pedals, shifter, and steering to be positioned in the "right" place just like a factory car. I finally settled on a dual brake and clutch pedal assembly from Wilwood and a gas pedal from Lokar. Fortunately the Tremec 6 sp with a Hurst shifter came out in the perfect location. I rebuilt the original power steering box and will plumb it into the Viper power steering pump. I was told that the pressure was close enough that it should work fine.
