Thats how they hit me. I heard about them when someone called them a boat anchor while they ripped one out for a small block 350. Then I started reading up on why GMC had its own motor when they could have just used a chibby motor like they do today.
It didnt take long before I like them and had to have one. Fast forward a few years and the only one I knew about close to me came to live with me and im glad it did!
