I like the truck style. 360? It's been awhile but who doesn't like a big block.

Still haven't found Makuloco's quote but I did find what he says about Ford's 15 lbs of oil pressure at idle, at temp. He prefers 25 lbs. This is from his video on checking oil pressure and might explain his preference for the 30 weight oil?

 

I skimmed through the video too... didn't hear it, lol. I don't have time to watch the whole thing right now.

AK.... dent side looks like it is in pretty good shape. I'd have a hard time passing on that. Where is that at? Looks like snow is in full force there.

 

No worries fellas. Thank yall for taking a look and sharing your thoughts. I suppose I'll stick to the 5w20 and keep on the 4k oil change interval just to be safe.

 

About 20 years ago I became a member of The Henry Ford because it's where Ford archives their engineering and design data. At the time I wanted to look at the work my dad did on this engine, http://theoldmotor.com/?p=22104



I stayed a member because of the amount of information available.

A little while back there was a discussion\argument going on in the General Discussion forum about oil weights. A common argument was about "Where's the documented evidence that running higher viscosity oils can damage an engine?" It was obvious from those insisting on the benefits of higher viscosity oils couldn't be convinced by any evidence. They also couldn't provide any counter-evidence documenting improved performance from using the higher viscosities. Generally their opinion was based on, "I read on the internet. . . "

Ford started discussing the manufacturing principles behind the Modular Engines in the 70's because of the proliferation of ISO manufacturing standards and actual work on the engine started in 81 or 82. What started on paper ended with prototyping over 500 engines for testing and research. A lot of the testing on those 500 engines had to do with lubrication. Engineering data isn't an exciting read that will keep you in your seat but it is noteworthy that the effects and differences between an oiling spec of 0.0007 and 0.0005 clearance doesn't involve arbitrary or "I think," decisions. Many hours of verification testing was done to support the decisions made. Engineers aren't ignorant when they make decisions. They are well aware of the difference between testing and real world use. Because of this they often make decisions based on it's better to over engineer\design than not to. Examples of this are a deleted PS bolt and changing a oil pressure spec from 25 PSI to 15 PSI because time had shown the precautions taken weren't necessary. Better safe than sorry. I think it's safe to say that by now if the engineers at Ford felt a 30 weight oil was a viable option they would have said so. They haven't though.

JP, next time I'm at the Henry Ford I will look at what's in the engineering data on oils and maybe there's a condensed report on Modular Engine oil research. Some of the prototype engine reports are more than a couple of hundred pages long because of pictures, charts and graphs. Looking for a specific data point in the reports can be like the proverbial needle in the haystack. Regardless, I'll try to find what's behind the oil viscosity specs for the Modular Engine. There's also the possibility that any rethinking of the oil specs or newer evaluations won't be at the museum. I'm just guessing at the timing used by Ford but there seems to be an approximate gap of 10 years before engineering data is sent to the archives for public viewing. There's also some data that is never sent or if sent, isn't available to the general public. I've tried to look at the early information about the collaboration between Ford and Cosworth and Ford and Westlake and it's not there or not available.

 

Thank you for taking the time to share River. When I get out of the woods and back to the office I will sit down and read through it all properly.

 

I wouldn't mind getting that lol.... road trip from AK to IN would be fun too

If it's rust free and you want to buy it and hold it for a year, I'll come visit and buy it off ya lol can't do anything too crazy till we move

 

LOL Was in a mood to yak and what I wrote can be reduced to I'll attempt to track down Modular Engine data in the Ford archives next time I'm there.

 

Good duct tape comparisons

 

Enjoyed this, thanks.

 

No problem, I love his channel because they depth of his testing is outta this world, plus as he mentions he's not sponsored and buys it all himself so he's not swayed to say which is better.
