Bringing an old thread back to life, but here goes! Got into on what appears to be a 1974 360 industrial engine that looks like it came from a COE or LCF truck. Has an oil pan like a car except it holds eight quarts and has an oil temperature sending unit and a drain back for an oil cooler. Cylinder heads have 18mm seat plugs with a reduced spark plug angle. 3 stamping on block, indicative of special rods and pistons from the LA identification page. Balancer with scallops and drilling instead of the offset weight inside and 30 degrees of BTDC marked on it. Double roller timing chain. I took some pictures but will get some more. It has an industrial cylinder head with 318 sized ports but appears to have been equipped with exhaust crossover. The casting numbers on the cylinder heads are 13151857, ad they have a temperature sender in the rear of the head as well as one in the front on the intake. It was equipped with an automatic transmission. VIN numbers stamped on the block below the K80 360are 026240.
The other 1974 360 we have to tear down is from a school bus, according to the information on the build tag and the remains of a governor that's adapted from a cable operated cruise control setup. It's also an automatic, and it has 974 heads with heavy duty exhaust rotators and blue intake and orange exhaust paint coded valve springs (same as the 857 heads).
The third one, while not industrial, was really cool to begin tear down on. 1971 HP 360. We suspect it to be a police car engine. Flat top pistons with no valve reliefs .060 from the deck at TDC. 915F casting J heads (1.88/1.60) and a 1971 340 four barrel type intake manifold. I'll get casting numbers to compare it to the 1971 340 intake, but I'm certain they're identical. All three engines are still as they left the factory. The industrial engine has so few miles and so little wear on it that we are going to re-gasket it, change to a regular truck type oil pan, and add a performer 318/360 intake with a ThermoQuad and a ready to run MSD type distributor "one wire fire" ignition. From there, it's going into a truck to use.
