They were available from 1963 to 1989. The early ones had a six balancing weight crankshaft and later had 12 weights. They have a 3.870 bore with a 4.125 inch stroke. The block is taller than the 194, 230, and 250 engines. There are propane pistons for them that bring the compression from 8.0:1 to 9.0:1. Many other high performance parts are also available. Built stock with some headwork makes them a very desirable. Last forever and easy to service. Not a high revving engine like jap motors. They are hard pullers and develope their torque on the low RPM range .They were used in pick ups, school buses up to 2 1/2 ton trucks and a few not so large trucks. Very rugged design, reliable and very successful. I just ordered one for my p/u.

OOOOOPS, I'm sorry. I did not see you were looking for answers on the Blazer. However in the Blazer they were available from 1970 to 1971. I have no idea why they just went with the 250 or the V8s. They have the same bolt pattern to the bell housing as the V8s do. They use the same motor mounts also. I k now, I am replacing a 350 with a modest built 292. Stock cam, balancing and propane pistons with later on cast iron headers and 2 single barrel carbs or a small 390-500 cfm 4 bbl. For off roading the 292 is far better than a sbc anyday. I have had both. The 292 will out pull them and out off road them without spinning the tires as much. Don't have to rev up the 292 much to get the torque out of them like V8s. Its torque you want not major hp. Torque gets you going and hp just maintains it. I hope this helps.

A friend had a 78 K5 that he ordered new specifically with a 292. He did a lot of hunting. Gordon
