Automotive journalist and racer Evan Smith, alongside Brian Wolfe, the former director of Ford Racing, continue their deep dive into Ford’s new 7.3L Godzilla engine which will power the 2020 Ford F-250 Super Duty pickup (and untold numbers of future hot rods and race cars).
In today’s video, these two dissect and explain the engine’s variable displacement oil pump, as well as cover the Ford 7.3L’s entire valve train, including the camshaft, hydraulic lifters, the 3/8″-diameter push rods, 1.8:1-ratio rocker arms, valves (2.17″ intake; 1.67″ exhaust), and valve springs.
In case you missed it, we shared the first three Ford 7.3L videos made by Smith and Wolfe for Smith’s excellent REVan Evan YouTube channel. If you’re interested in this new monster engine from Ford (and who wouldn’t be?) we strongly encourage you to explore all of the videos and subscribe to Smith’s channel for future videos, which are likely to include 7.3L engine builds and performance upgrades.
Today’s video opens with Wolfe pulling apart the oil pump to show us how it works, before taking us through the various valve-train components.

While I have a lot of respect for Brian Wolfe, this oil pump design is way over complicated and I believe will be really prone to fail. First fail is the Chain drive. This is about the worst way to drive a pump, then a long shaft ( reminds me of Porsche intermediate shaft design, which fail and destroy the entire engine). too much chain tension causes the shaft to wear in it’s bushings, shaft becomes out of spec equals fail. This whole girdle looking design, way complicated and I just cannot see the variable pump vanes lasting in the real world. A gear oil pump like in a automatic transmission is simple and it works forever as long as there is oil in the engine. Ford does not do extensive testing, much like the 6.0 diesel debacle the customer will be the test audience, it’s cheaper for manufactures this way. Just my opinion after working on this stuff for 50 years.
iv worked for an enginering company that tested vehicals for manufactures. they only test vehicals for a year and up to 120k miles. basically to see if there are any problems before the warrenty period so they dont have to worry about fixing them. then dont care what happens after the warrenty period.
Thank you for making us read this well written article on the godzilla engine overview. I enjoyed reading this article. Such illustrations are given that a layman could even understand. It is an easy to comprehend blog which can be instigated by all at least once. I am sure many people will come to read this in future.
