Cornbinder Posted September 13, 2015 Cool! I've thought about making up a Big Al for an old truck, looks like you actually went and did it. AC had a couple of semis they used as demos at truck shows- I know one was a KW cabover, and the other was a conventional Hendrickson. Share this post Link to post Share on other sites
PaulCRW Posted September 23, 2015 Wow, fantastic job, and thanks for the education. Had never heard of the Big Al engine before. Share this post Link to post Share on other sites
Cornbinder Posted September 24, 2015 Big Al was a little too far ahead of its time- it was making more power and was more fuel efficient than other engines of the era. The trouble was, it was a bit too far ahead of the curve and got kind of a nasty reputation for being a ticking time bomb. One problem was you had to take it in for service and repair at an Allis Chalmers heavy equipment dealer... not as many of those guys around as there were for, say, Cummins. Big Al was based on the earlier Buda 844, AC having bought out Buda Engines in 1953. Share this post Link to post Share on other sites
