i have one complete throttle body to oil pan, good running 350. i took it out because it had a rod knock. the motor ran fine. the heads are in excelent shape, and it never had a problem besides this rod knock. it would be great for some one doing a tbi swap, or some one who had a need for a good upper end. i never pulled the pan and, and i dont know how bad the rod or the crank is, all i know is that it had a rod knock and i drove it into the garage and took the motor out. motor is being sold complete only, as is where is. no warranties, no i wont pull the pan. its a parts motor, or a very good rebuildable core. asking 350 or trade for tires.
