5W-20 in a 2013 Mustang GT? Seriously?

The Cammer is one of my favourite engines (as is the BOSS 429). My grandfather had one in a Thunderbird, thing was a rocket ship!

The original Modular was supposed to essentially be a modern reincarnation of this mill. Unfortunately, it wouldn't fit in a FWD setup, so they shrunk the bores and subsequent overall length (bore centre spacing) to give us the 281/4.6L. However, the original project was not scrapped. Dubbed "Hurricane" it was given some attention later on but eventually renamed "Boss" due to Katrina.

this is the engine that became the big 6.2L V8 that showed up in the F-series and could readily be grown to 7.0L/427ci.

The Coyote is a derivative of the Modular and shares the smaller bore size and spacing.
 
I never figured that someone would dig up my thread from June 2012.

But - please carry on.

Yes I wondered about this as well.

Maybe you're younger than me and have never worked/rebuilt an older conventional V engine. I don't know. But, does it bother you that I stated UPPER CAMSHAFTS?

They are called "Overhead Cams". The design and term DOHC has been around a very long time - Dual OverHead Cams.

It's still camshafts on the UPPER part of the engine. Tomato, Tumotto..........it's still a fruit.

I agree with what this guy says. Brilliant post; couldn't have said it better myself.

Where are the lower cams at in an engine with upper cams?

I think there is one cam above another cam. So, below the UPPER cam.
 
Not 100% sure but I think all my cams are the same distance from the lower crankshaft. There's no way to know which one is the upper or lower.

Be honest with me, if you can. Are you and some others here more focused on my inability to call the position of a camshaft or, are you more interested about the subject matter of the title of this thread?

This thread is like 6 years old with tired content. Upper and lower cams is way more interesting. I was at the airhow yesterday and saw hundreds of radial engines with center cranks. Never mind the engine design with TWO cranks, upper and lower. We've been tossing generic crankshaft term around too long.

If y'all keep following me around and correcting my mechanical engineering mistakes of the internal combustion engine, the MODS will see this and shut down the thread. Then, where will you follow me next?
Back to the subject, does it really matter, in theory, if one uses a 5W30 over a 5W20 in the GT? I still think the oil (5W20) gets to the UPPER CAMSHAFTS quicker than a 5W30. But, don't most 5W30's shear own to a 5W20 in all actuality?
 
I thought the different in timing the flow between 5w20 and 5w30 was in fractions of seconds?

Second, if the 5w30 shears to a 20 in your estimation then what happens to a 5w20? In the end, it’s the lubrication of the camshaft/s that is important so a lot more variables to consider.

I DON'T know if a 5W30 shears down. I just put that because I have read it here on BITOG. And, I also read that a 5W20 had such a great add package that it wouldn't shear. Don't ask me WHERE EXACTLY I read it here, but I did.
I'm in uncharted waters about oil shearing. And, I'm not scared to admit it!

He's also banned.

The PD pump will send the same oil volume regardless if it's 5W-20 or 5W-30. Now if you were talking about 5W-20 vs 20W-50 then amount of oil flow comment might be applicable if the PD pump hit pressure relief with the 20W-50.

OKAY, the 5W20 is thinner to get into the places better than a 5W30 can?
