I'm betting those force fed little hamster wheel powered mini motors are not under the same stress as a 6,000 # truck engine.

 

Flatheads were way before Boomers, and lots of people are still driving SBC engines. The LS series engines (minus cylinder deactivation) are some of the most reliable V8s ever. Typical dismissive ankle biters who have no respect for anyone.

 

The LS is not a SBC. The 90s are calling.

 

Its human nature to dislike change.

I suspect there wont be any posts on here in regards to failed oil pump belts even 10 years from now.

 

im not being condescending! 😂 it’s pretty frickin easy to change an intake manifold! Im just telling you it’s not gonna make much difference look it up! There is plenty of testing done comparing Coyote intakes. It will look cool when you pop the hood though!

 

But do before and after dyno with just the manifold and tune though 😂 but I’m not being sarcastic when I say it would look cool I mean it really would 😂

 

I still choose a chain over a belt for timing. I didn't buy a Highlander for several years because they used a belt. I bought one once they went to a chain. I make a lot of money changing belts. Lol. Just added expense of maintenance for no gain.

Thats one good thing no doubt. But I have always said Ford screwed with too much. And usually it brought more problems than not. The three valve tritons. The PI heads. IWE instead of hubs that worked for a billion miles. Lol.

So who's point are you making here. Ive seen about 100 oil pump drive or distributor gears or shafts broken. Ive also seen cams ruined by the oil pump drive. If the oil pumps had been belt driven i know of many catastrophic engine failures that wouldn't have happened. Probably just as many or more than it could cause.

Ive seen them eat the drive gear in a few thousand miles when the cam was a bit much. Thats why they make mid priced bronze gears and even 100 dollar steel distributor drive gears. Having the pump seperate from all that would at least isolate the pump from screwing up the whole motor if it fails.

And its most certainly not a cost cutting thing. It would have been far cheaper to keep what they had than it would to develop the new pump .

I service several 150-300 HP 660 volt AC motors that run several thousand lb shafts.....via a toothed belt. 24/7 for many many years. In industry most things are belt driven where they were run via greasy gears up until around the 00s.


In all fairness GM DID call the LS the gen 3 small block. And the LT was spanking the fancy ohc Ford v8s up into the 2000s. It's kind of like when we call a silencer a silencer a people say "blah blah it's a suppressor not a silencer". Hiram maxim patented it as a silencer. He gets to pick the name... not me. Same for calling a revolver a pistol. The inventors get to choose the name. Not someone 100-200 years later. Lol.

Chevy did keep the cam in block design through it all and pretty much always made more power than Ford could manage with their fancy ohc cars and trucks. Always pissed me off. I own 86, 93, and 04 mustangs. In each of those generations the camaro/TA would have had more HP. Lol


I have a new 5.0 with the belt driven oil pump. I trust the oil pump more than the 10 speed or the IWE or the top end. If it breaks Ford will fix it. I really don't care. The 5.0 was my choice over all the rest.

 

Temperature Range -57°C to +121°C

that is my point.. chains do not have such a range.. belts do. i too have been impressed with cog belts in an industrial environment (chem plant) though they don't have to survive in a hot oil bath. We will see.. i still would trust a chain more.

And i would think we deserve a real-time oil pressure to monitor this new approach to the oil pump drive..

 

If the oil gets over 250f you'll have other things to worry about other than a belt gaining some elasticity.

 

well.. i don't think they will "stretch" as much as "shell" little pieces as the belt loads, wears and gets hot. What i have seen in plant operation is that the belt keeps its tension but loses the "teeth" as they wear from time, load and heat. i am sure the belt will go five years.. i don't think it something that can go without attention forever.
