Re: Crate Engine?

Those GM crate engines are a bargain, but they range in price dramatically. I have the 260hp 350. It had an unknown number of miles on it when I purchased the truck. It smoked really bad and I had to have the heads rebuilt. One was cracked, and 15 of 16 valves had bad seals. I figure it was probably from it overheating and I don't contribute it to the manufacturing company. Also, it still had the honing crosshatch in the cylinders, so I don't think it was ran hard or beat down. I did however run the torque sequence on the main caps just for security, and one bolt head was cracked and sheered off around 15 ft lbs. Take all this with a grain of salt, and hopefully others can chime in with much better stories about these crates. All that being said I'd strongly weigh the price vs an LS swap, or even a rebuild.
