Factory Engine Specs?

[Kotta390]

Ok, so this maybe a long shot on some of the things I am asking for but I wanted to see what you guys knew and what we know about our STOCK 09+ Hemi engines. I have compiled a list of questions and lets see if we can answer them? This is purely for informational reasons only. If you can add to the list that will be great and I will update this thread as we answer these engine specs!

That did help some, but I am a little confused on the intake sizes where it talks about intake valve is 2.04-2.06 and exhaust is 1.55-1.56???? WTF??


Also the camshaft is measured at the manufacturer spot for measuring duration so I need to know what the LSA is still and what the duration of intake and exhaust is at .050?


Otherwise that's a great start!

 

[Kotta390]

186 @ .050 intake duration.

205 @ .050 exhaust duration for MDS cylinders.

208 @ .050 exhaust duration for other cylinders.

115 LSA

103 ICL

38 degrees range of motion.

Thank you!

 

[Kotta390]

Ok so now The last two pieces that are pretty important are the connecting rod length and the ACTUAL stock TB size, whether it is 09-2012 and 2013+ I am just seeing if they are the same size and if not then what is the size of both?


Also does anyone have any real info on the Eagle heads and flow numbers in stock form?

 

[Kotta390]

Corrected the rod lenth above, did if from memory and though about it and was off.

I was just wondering to myself that those are the same 6.125 rod lengths the magnum engines use lol.

 

[Kotta390]

Does anyone know the intake and exhaust runner volume in cc?

 

[jcfoshe]

Have a question, my son has a 2010 ram 1500 with 5.7 hemi and need to know the connecting rod length. The about confused me a little by what is the actual length, 6.125 or 6.240? Also what is the difference in "eagle" heads and magnum engines?

hey thanks for the info I have a 2015 5.7 would the bearing clearance be the same or did they change?

This needs a bump up
