The 3306/3406 engines were pushrod engines and would have been a much simpler and cheaper engine to build than the complicated overhead cam 1600 series.

I don't imagine Caterpillar really began to rival Cummins in terms of truck engines sold until they brought out the 3406A series engines in the 1970s. Caterpillar re-entered the truck diesel engine market in about 1958 with their twin overhead camshaft, pre combustion chamber, turbocharged and aftercooled 1600 series motors-I think the 525 c.i.d. Cheers T Tutlebrain, it would seem that from the late 1940s onwards Cummins pretty much had the OEM truck diesel market sown up, at least until General Motors started selling Detroit Diesels to other truck manufacturers in the late 1950s-early 1960s. There must have been a reason why they were not successful? Another obscure manufacturer was P&H, some info on this thread: and that HCVC thread: One has to assume the others were as reliable as the P&Hs or they would have been more successful, as both Waukesha and Conti were large companies with good reputation and dealer network. I did not even know those manufacturers were producing diesels. Waukesha diesel engine advertisement from 1954 featuring Diamond T and FWD trucks. Does anyone know if either of these engines were used by any truck manufacturers? The diesel would use the Lanova combustion system, or as Continental refers to it-"Cushioned Power". Continental V8.603 gas and VD8.603 diesel V8s from 1955.
