wildebill308 Report post Posted March 6, 2019 Ford Introduces New F-53 V8 Engine, Transmission. The new 7.3-liter V8 engine is paired with an all-new 10-speed TorqShift automatic transmission. https://www.rvbusiness.com/blog/ford-introduces-new-f-53-v8-engine-transmission.html Should be a interesting upgrade for the gas RV market.

rfsod48 Report post Posted March 6, 2019 Should be very interesting, more hp and torque than v10. Might be a good upgrade for me if we continue with RV. This year with going a shorter distance has been easier on my wife. Share this post Link to post Share on other sites

five Report post Posted March 7, 2019 No mention of MPG...they said "a step up in performance and fuel economy." I wouldn't hold my breath. Share this post Link to post Share on other sites
wildebill308 Report post Posted March 8, 2019 Well as we all know mileage is more of a component of weight and wind resistance and driving conditions. (why am I always driving uphill into the wind?) It would be hard to get accurate guestaments till someone builds something to test. Bill Share this post Link to post Share on other sites
manholt Report post Posted March 8, 2019 I would guess that with a 10 speed auto tranny your mpg would be better than a 5 or 6 ! How much, depends on individual habits & what Bill said. Share this post Link to post Share on other sites
rayin Report post Posted March 8, 2019 It sounds like Ford has placed a large long-term bet on this engine. It is designed to fit into any vehicle with adequate space. It can be placed into a Mustang, full-size trucks and vans all they way to include the Ford F750. Share this post Link to post Share on other sites
manholt Report post Posted March 8, 2019 Push rod, wonder how hard it is to change out the bearing, when it wears down? Hope you don't throw a link on the chain! IMHO, true 1 ton & up, I want a million mile diesel. Share this post Link to post Share on other sites

The base engine is capable but the emissions system cost 2x the price of the engine it it will not last that long! Share this post Link to post Share on other sites
jleamont Report post Posted March 8, 2019 I am good with a pushrod engine, especially with roller lifters and roller rockers. Ran many high HP engines over the years with that set up and never had an issue. Anyone else notice the size of that exhaust valve . Looks like a monster from the factory!
