There is no comparsion between a 300 Ford six and Chrysler 225 in heavy duty use. The Ford 300 is built to handle much more abuse. The 225 is a light duty engine, 4 main bearing crank and timing chain, better suited for a light commuter type vehicle. The 300 is a seven main bearing engine with timing gears designed for punishment. United Parcel Service counts there pennies, and used 300 Fords and 292 Chevys in hard stop and go delivery work, 225 Chryslers were tried, but soon abandoned.

 

Is it just me, or are longer stroke engines seeming to end up in the longer lasting category?

 

Wait UPS tried the slant six in their trucks?

 

300/302 best and 6.0l garbage

 

Yes, big fleets expirament with everything available, if the truck makes them money, they keep using it, if it looses money, they move on ( or forced to move on by more stringent emmission regulations). Businesses are in business to make a profit, not for charity. U-Haul once expiramented with Dodge trucks in the very early 60's, then switched to Fords.

 

IMHO, you should only compare gas engines to diesels on years that they had to use new emission technologies.

In 2003 when the 6.0 came out, gas engines were years and years past any dramatically new emission system.

Maybe we should dig up some gas engines from the first year or 2 with emission systems being put in place.
Just sayin.

 

ok very true
cant compare an older gas to newer diesel with emissions
but you can compare a 7.3 to a 6.0
you bulletproof the 6.0 its just as good.. no bulletproofing.. just junk it
but a 5.4 and 6.0 can be on the same level.. but i have beaten the living sht out of that 5.4 in 20 inches of snow
but i dont think you can beat a 300 six

 

Why don't you slap an EGR system on a 7.3 and reprogram it to 325 HP. I wonder how reliable it would be then.

Are you also tearing down the inline 6 that so many love around here ?

 

i own a 63 f100 with a 223 inline six???
i never said i disliked it.. i think it beats almost any other motor out there

why dont we get rid of the egr on the 6.0 and re-tune???

 

EGR was not new, had been around since at least the early 70s on gasoline engines, and a good few years before the 6.0 on diesels.

Look at the first generation 7.3 PSD - they were cutting edge. Fully electronic high-pressure direct injection Diesels with catalytic converters. They didn't have mass-failures like the 6.0

The 6.0 was rushed to market and under-engineered. Getting rid of the EGR still doesn't fix oil cooler failures, turbo vanes sticking, and head-gasket blowing.

 

Haha I thought you meant you couldn't beat it; like as in you couldn't beat on it cause it can't take it . lol.

Take a 6.0, delete the emissions systems, reduce the fuel pressures to 7.3 levels, reprogram to 270 hp, and I'd buy one in a second. Would probably outlive 7.3's.

 

Thats almost exactly what i would do.. egr delete.. dpf delete.. put a straight pipe on there.. retune it and add some bigger injectors..
i would do the same..
now we're on the same page..
but a 300 will outlive a diesel or any gas motor..
300 is almost based on a diesel block..

 

i still like my 223..
but i hate when people add these chevy/mopar motors to equation and say there "good"

 

DPF delete was standard equipment from the factory on all 6.0's

 

lol why bigger injectors?

300's are great, but I'd say lifespan is not quite diesel lifespan in the same era. I know a guy who had several, and still has one. They all crapped out after running semi loaded for 600,000 km's, which isn't anything to snort at. Usually just top end and stuff, some got a 2nd life and made it over a million KM with just a few hundred bucks worth of parts.

He's got one now, driving it occasionally, it's got 1.2 million km, but it's been rebuilt 3 times.
