I just picked up a 2010 ram with the hemi in it. Could someone enlighten me on what the cubic inch, horse power, torq specs are on these engines.

 

Thats all on the Ram web site from Chrysler. It even has a graph to show you what hp and tq it makes at what RPM - interesting. Anyway 350 cu in, 390 hp and 407 Tq. Pretty sure from memory.

 

It is just a little under 350 CID.... I think 345. Anyone want to confirm? I am lazy tonight. HP/TQ are correct.

 

345cid is correct

 

Displacement 5.7 Liters 348 CID

 

Incorrect, the Hemi is 345.

 

hey guys i have a quick question about the hemi engine......... when driving between 45 to about 70 mph im hearing a weird noise coming from engine when giving light pressure on gas....just wanted to know if you guys have some weird noise too, its done that since i got it so might be normal

 

maybe the MDS is on? What kind of noise?

 

I'm quoting the 09 service manual. So if they changed it in 10, I stand corrected..

"The 5.7L engine (348 CID) eight-cylinder engine is a 90° V-Type lightweight, deep skirt cast iron block, aluminum heads, single cam, overhead valve engine with hydraulic roller tappets. The heads incorporate splayed valves with a hemispherical style combustion chamber and dual spark plugs. The cylinders are numbered from front to rear; 1, 3, 5, 7 on the left bank and 2, 4, 6, 8 on the right bank. The firing order is 1-8-4-3-6-5-7-2."

 

The noise is hard to explain, kinda sounds like the computer is shorting and when eco light appears the noise seems to go away
