excerpts;
"...From 1977 to 1982, the M-block (351M/400) V8 engine was a mainstay of Ford light truck powerplants. During that period, the M-block 400 was the largest engine available in any Ford 4x4 truck. In the 1978 and 1979 model years, the 351M and 400 were the only engines offered in Ford’s new, full-size Bronco. The ultimate cruel irony in the M-block’s history was that it was so well adapted to first-generation emission control systems, it was not easily updated to work with more modern engine management systems, and it was dropped from production at the end of the 1982 model year;
Build Date Stamp
The original build date of the engine is stamped into the front cover surface, toward the right side of the engine. Often this stamp is behind the front cover gasket so it is not visible with the front cover plate on the engine. In this case, it was outside of the front cover gasket.
The build date was the date on which the engine was assembled at the factory. The build date code in this picture is: “78G190” This translates to July 19, 1978.
The following table lists Ford advertised power ratings for M-block engines from MY 1971 through MY 1982. Horsepower figures are not available for some years, and torque figures are not available for many years. Ford did not always advertise M-block torque figures, and I have not yet been able to find reliable horsepower figures for the last two years of M-block production (1981 and 1982;
1980
351M (truck only)
138 HP @ 3400
263 Torque (ft/lbs) @ 2000 RPM
1980
400 (truck only)
163 HP @ 3600
275 Torque (ft/lbs) @ 2000 .."
Much more!

Note that Engine Code does not correlate to VIN's engine code in any way
Some Info is easily identified, but the reat is very diff to interpret and so far, I have not been able to obtain a Legend (over past 40+ years)
Build Sheet Location Synopsis; Locations vary because it depended upon who threw it in the Bronco on the production line vs. those who took time to place it same place for 18 years: "...under the driver's or passenger side carpet, in the fiberglass top hidden behind the rear trim piece, driver's side in a 79 by Ziggy; was under the rubber mat under the driver's seat in a 78 by Scoop; under my carpet on the right side in the back in a 92 by M. Cardholder; under the carpet directly behind the front passenger seat, Under the cardboard spacer sheet/heat shield in an 88 by Dustball; under the drivers side of your front seat between the seat springs and the cushion in an 86 F 150 by Hoxviii; underneath the carpet under the drivers seat and another in the back end underneath the carpet in an 88 by Xris; Ive found them in the back seat front seat Passenger floor Board and head liner. Gently feel your back seat for paper under the vinyl. Same with the back and then under the seats. Possibly under passenger carpeting rubber mat in a 78 by F1rocco; under my rear deck carpet and padding, taped to the bed in an 89 by Buckin' 89Bronco...";

In 1980 Ford upgraded the Bronco to the new Twin Traction Beam IFS front suspension and restyled the body. This new suspension offered a better ride and more terrain compliance on rough terrain. With an eye on the off-road use the Bronco was built for, Ford upgraded the transfer case to a New Process 208 with a 2.61:1 low range. This new transfer case was also better sealed against the elements. The standard motor for the Bronco was now the venerable 300 cid I-6 in all states except California where the 302 cid V-8 was standard. Optional engines were the 302 cid and 351 cid V-8s. All engines featured 2-bbl carburetion. 1980 also saw the introduction of 3.00:1 as well as the 3.50:1 gearing. Automatic locking hubs were now optional on the Bronco. The restyling increased front leg room by one inch while decreasing the Bronco's exterior dimensions. The 1980 Bronco was 2.7 inches shorter in the front end and 1.1 inches narrower than the previous year. Wind drag was reduced by 25% and a new grille featured rectangular headlamps.

Enjoy your Bronco!
