Boo, the C15 is a 1/2 ton truck. A 3/4 ton would be a c25. My 1965 1/2 ton has a 292 with headers, HEI and a 5 spd with 3.73 gears. I had originally run it with the factory single barrel, headers and HEI but when it goes back on the road it will have the aluminum intake with one of Stovebolt's Progressive Holleys on it. Also power steering and power disc brakes. This is one awsum combination in my opinion. I tow my race car and trailer with it and it just keeps on working. The only other update that I like as much is to put an early 90's Chev seat in your truck. They are so much more comfortable and basically a bolt-in. I used a 60/40 split but there are all sorts of combinations and materials out there. You will definetly enjoy it.
