The 302 is a great truck engine and can be made better. A problem you may have on most of these sites is the main focus in on Hot Rod/race engines. They are different from truck engines. The difference would be in the head and the cam. You will know by the time you get home if you want to keep the 302. I'm sure there is a better transmission for this rig. Adapting it to the GMC might be a whole other project. I'm not sure.
Another site to check is Stovebolt lots of truck stuff there. Chevy mostly but quite a bit on GMC.
STOVEBOLT I love the CARS connection. I hope you don't have to deal with the snooty RV Parks with their new only rules, no class and no classics.
