Besides service in large luxury cars in the 1970s and in trucks throughout its life, the 385 series engine was also popular in motorhomes, marine, and industrial applications. Over 50 varieties were produced in any given year. As with the FE line of engines, Ford also offered Cobra Jet and Super Cobra Jet versions of the 429. The Cobra Jet, rated at 370hp (280kW), was equipped with a Rochester Quadrajet carburetor, larger camshaft, 11.3 to 1 compression ratio and a special set of cylinder heads. The Super Cobra Jet, rated at 375hp (280kW), had a 4-bolt main block, a Holley carburetor, and a larger mechanical camshaft. In 1971, the CJ engine also used a 4-bolt main block. However, these engines were actually underrated and produce power in the 440-460 hp range. This was done to deceive insurance companies (common practice in that era), so that buyers did not have to pay higher insurance rates.



I tried, No luck,All I can figure out is that the engine code you do find should read something like a VIN# the first 3 numbers will be the decade produced and where it was made D0 or D1 or D3 should be Dearborn 70-71-72 that is as far as I got..
