This may be a dumb question but please bare with me, Im new to the game. Im about to buy an 83 K5 thats been sitting in someones yard for the last 7 years. It needs an engine and some other work. I don't plan on using this truck as a daily driver. This will strictly be my weekend warrior truck, My dog and my dad's fishing boat will probably accompany me more than anything. So towing capacity is important. I also want some off road capability. I spoke with a couple people who have all told me the same thing about buying a crate engine for this truck. The guy at the dealer parts dept, a mechanic and a relative all told me I would be better off buying a quality 350 or even a 454 block from a junkyard and rebuild it. They suggested that I could get the same performance and reliability if I get a solid block plus I could bolt on what ever performance parts and upgrades I want and come out way cheaper. Tell me why or if I would be better off purchasing a crate engine? Any particular other issues I should look into? I plan to tear this truck down waterproof the interior and a bunch of other things. BTW, can I get waterproof/ water resistant seats? I will also do most of the work myself. thanks alot for the help.
