Home Forums Hunting & Shooting Hunter's Campfire More on Ford's 7.3 L Motor

Probably. Splayed four bolt mains, forged steel crank, H beam rods, ARP nuts and bolts, hydraulic roller cam, etc. And it never spins above 5500 rpm. That said, I won't pulling a trailer in my Mach 1. Who knows if the new Ford will go 300K until it does I suppose. I do like their steer back towards a strong gas engine.

Yep.

300 straight six is the best gas truck engine Ford's ever made.

Ed- that stroked Windsor is nice.

Good luck getting it 50 state approved.


Hoping Ford hits a home run with it. They need some help catching up with the LS motors.

I have 6- 6.0 GM's in pickups and vans. The youngest has 100,000. The oldest has 354,000 miles right now. Uses no oil between changes. Buddy has a 3500 express van with 500,000+ with no work.

Have an 8.1l in a GMC. Talk about a badass gasser, sumbitch pulls like a freight train. I have 2 duramax's and the 8.1l puts them to shame.

Having put a bunch of miles on one......I won’t/can’t disagree.

My v10 is making a run though!

Bold talk!

I agree. Vast majority of drivers, even drivers of pickups, don't know to allow for warm up / cool down. I do such even with my NA gas engines. Get in, start it up, then attend to a few items for 30-60 sec at least. Then take off nice & easy until everything at operating temp. When I arrive, I take a minute or two to arrange things (and hopefully took it easy the last few miles), then shut it off. Thus far, in my metro area, no one has allowed me to wear out an engine before some knucklehead decides I need to buy a new auto and totals my current 10-14 year old daily driver. Not hard to do when it is 10+ YO and ~200k mi on the odo.

And even if the driver does take pains, the increased complexity is a source of failure. The intercooled turbo bits are not free and they all can break.



Do the turbos keep spinning or come to an abrupt halt with some sort of braking mechanism? If they keep spinning, depleting their angular momentum, the oil that used to circulate is now stuck and sucking in turbo-generated heat while at stop. This can't be good for that volume of oil or the parts it is supposed to be lubricating.

Don't get me started (yuk-yuk). It is not good for ANY part of the engine. Oh, but they get a heavy-duty starter. Really? One with, say, a 100x better MTBF to counter the increased number of starts? How much more does that weigh & cost? And how about the battery, AC compressor, and other bits that need beefing up to keep up with the increased number of starts _and_ the cessation of compressor/alternator operation at stop? If they aren't 100x more reliable, how much to replace those items? What if hte whole start-stop system goes apey 200 miles form home and maybe decides it won;t start up again?

And then there is the big honking deal static friction. The Ford eco-boost booster claim the oil pressure is maintained during the stop-start sequence. Assume that is true and no loss of pressure occurs. Well, starting a system from stop results in the system fighting static friction, which is greater than the kinetic friction one sees in a system at motion.

One thing we have to keep in mind with the stop-start and turbo gasser deals is that these were not foisted on us because the public demanded them. They have been foisted on us so the trucks do better in teh EPA fuel efficiency tests.

"What we need is a turbo V-6 gasser in our half ton full sized pickup trucks," said no one anywhere. Turbo V-6 diesel, sure.

Or you could just push the button on the dash that kills the Auto-Off feature...if you don't like it.

It ain't rocket science.

But I assume you'd have to have at a bare minimum... Driven One.... to make a knowledgeable assessment.

Nothing new at the Fire... (Hell there's more than a few in this very thread that are posting, thinking this thread is about the old 7.3 Powerstroke diesel engine... LOL.)

GMC Cyclone.


Next question please.

Does B&W make a turnover ball for those? Schweeeet

Probably. I am on my second one of those too.

I’d probably rephrase that to “longest lasting truck engine Ford ever built”. They’re good no doubt but most guys these days wouldn’t be satisfied with a whole 220ft lb of torque.

Did have a buddy who ran one to almost 600k with absolutely no engine work. In fact the only semi major work ever done to the whole truck was a clutch at around 500k. Couldn’t be in a hurry but it would deliver you to where you wanted to go eventually.

I am seriously looking at a Class C RV. I think the new Ford 7.3 would be a good fit, depending on the tranny. The V10 is a good one as well. Currently have a 35' 5th wheel max at 14K#'s. 2014 Silverado HD SRW Duramax 4X4. For this trailer I would never consider a gas truck. Yes I paid $8K to get the diesel and the Allison tranny. One thing I have not seen folks talk about is the exhaust brake and the trannys ability to slow the rig down with out using the brakes. On the long hills out West that can be a god send. Mileage is not bad, 7 to best of 12 with the 5th wheel. Empty 13 to a high of 17. Diesels also hold their value better as well. Dealer wants my truck on a trade, offered $40K towards a 2019. I only paid $48K when I bought it. You won't get that on a gas truck. If not towing a big load then the diesels don't make that much sense.

My 8.1l is in a 6500 series GMC with a Zf 6-speed manual and the duramax's are in 4500 series Chevy's with automatics so obviously gearing is a huge part of it. Like to run an 8.1l with an Allison sometime.

Saw one posted locally here, 170,000+ miles and they want $8,000. Would be neat, but not at that price.

8.1 L has enough power to drift a 28' U-Haul truck. Effortlessly.

Thankfully Johnnie Law wasn't around, but I had to make three lane changes in about 250 ft. ahead of rush hour traffic after making a left turn on yellow.
