Ford’s new 7.3 liter big block gas engine

Recommended Posts

This looks really promising for those owners who want a ton of low and midrange torque in a HD truck, but don’t want to go diesel.... I fit in that category. There are no power numbers yet but if it doesn’t make 525 ft lbs I would be really surprised.

 

It will come with a new Super Duty 10 speed transmission. It is a two valve pushrod design for compact design and reliability, port injection instead of direct injection (no intake valve carbon problems) and it is designed to run under a heavy continuous load while producing decent fuel economy. This is one complaint of the smaller turbo engines - under heavy load they don’t provide great mpgs.

 

This video goes into great detail about how the engine is designed; it is too way too much info if you are not a truck nerd.

I have never been a Ford fan but if they came out with a 2500 competitor for the offroad Ram Power Wagon with this engine as an option, I would think really hard about it, for sure.

I have a V-10 6.8 L, 5R-110 tranny.  Thirsty engine but robust.  I wonder how the new 7.3 will compare? 288 hp, 4000 rpm, and 424 lb ft at 3000 rpm for a V-10.  OK, maybe it will beat those numbers.  Then the question is durability.  10 cylinders to spread the load over vs 8?  It's hard to imagine anything more durable than a V-10.

 

Oh well, only 150k on my V-10, and I'm just pulling an Ollie.  It'll be a while before I need a new one.

Recovering Airstream Owner (The Silver Sieve)...it was a rolling apocalypse.  Fridge was quirky and ruined food (famine).  Had weird electrical problems, circuits with breakers thrown still carried some current (possible fire).  Leaked (flood).  Mildew from leak gave me cold-like symptoms (pestilence).
