Pat Flood (@rebarcock) passed away 9/21/25. Pat played a huge role in encouraging the devolopmemt of this site and donated the very first dollar to get it started. Check the thread at the top of the board for the obituary and please feel free to pay your respects there. I am going to get all the content from that thread over to his family so they can see how many people really cared for Pat outside of what they ever knew. Pat loved to tell stories and always wanted everyone else to tell stories. I think a great way we can honor Pat is to tell a story in his thread (also pinned at the top of the board).

Camshaft and all the valve train parts. Also had to put a new pan gasket on since I tried to replace the camshaft the old way and not remove the pan completely, the yoyo that robbed me put a cheap oil pan on and used a one piece gasket, you can't get the timing cover back on if you have that combo. An old oem pan and you can replace the timing cover all day long with out having to drop the pan, not with this new style oil pan gasket. I am keeping my fingers crossed there will be no leaks on that new pan gasket. If there is I will order a new oem pan and gasket set and take it to a good shop and have it replaced. I don't have the time or inclination to crawl under the truck again, especially in cold weather which is coming soon. It took me months to get this far due to my health and age. My knees don't bend so once down on the ground I have a very hard time getting back up. The engine is starting now without any issue and I got my vacuum back so it idles nice. Sounds like this cam is no more than an old Z-28 camshaft. It is listed as a motor home camshaft and is mid range, so was the z-28 coming in at the 2000 rpm range. I had one in my 67 Chev Truck, it ran really strong but the gas mileage was great. In 76 I could buy 5 dollars of gas and drive fast to Galveston from Houston and still have gas when I got back to Houston. I had a Holley 600 carb and it was a good combination for the freeway driving. This setup on this gmc is a straightbore 600 and the weight of the truck is a lot more than the old 67, tires are taller and much heavier. I still expect the mileage to be good because I don't drive on the freeways and the truck is low geared so it pulls low range very good.
