SB 2254 1968 Series Two

Mostly original except as follows: 6" and 8" Revolution wheels, Caterham rear wings with incorrect tail lights, Caterham Nose and Bonnet (needed to clear the cam cover) and of course the wrong engine which is a 1558 Twin Cam built in 1980 by Nelson and represented to be 140 bhp. I don't know if it really produces 140 bhp, but I assure you it is wicked fast. My theory is that if the car is going to have the wrong engine, I have the right wrong engine. I have had the radiator re-cored with a modern 4 row core and it never overheats. The only other change is that I installed a dual circuit master cylinder for the brakes. I thought that this was a good idea.

I really can't decide which car I like better. The green one is easier to drive and go fast in, the red car has been restored, looks better, and sounds more like a race car. Neither car is exactly correct and I'm not sure which one is the correctest. I am glad to accept input to help me decide.
