Thanks again Mark. Another engine that I have is a 1964 283 with PP heads and a powerglide, needing rebuilt as well. That would be more period correct if I went with a small block. Of course, if I run across any good running small block of any vintage, that might just make things easier. lol I also noticed that GMC had leaf springs on the rear of their 1/2 tons while Chevy had the coils. I assume the frames would be different in this area?
