The GAR 35 coupe in the Tex Smith book did use a 37 engine with block offs so it would be a 21 stud with head mounted pumps. They bored all 8 cylinders for big sleeves. They wanted a 4 inch stroke 255 with thick walls so they spent a lot of time & money to get there. They did mention that the reliability was what they wanted in the mountain country and I guess it worked out OK.
