What kind of bearing do I need for a hemi engine?
These engines require a unique bearing set with a wide front bearing that has two slots that are located directly over the grooves in the cam journal and the number three bearing is babbit coated to “reduce friction at a critical point on the cam, which improves durability during cold operation.” Dura-Bond offers a bearing set for these engines.
What kind of engine does a Chrysler Hemi have?
Image: Brian/Screenshot: GearHeads/YouTube. Art by Jason Torchinsky It appears that Chrysler royally screwed up, and owners of 2011 Jeeps, Dodges, and Rams equipped with the legendary 5.7-liter Hemi have paid for it dearly.
Why did Chrysler add variable valve timing to the Hemi engine?
That’s probably why the MDS system has been so successful and trouble-free in these engines, but the original block wasn’t designed to include the variable valve timing ( VVT) that was the next step up in technology, so Chrysler had to redesign the block in order to update the engine in ’09.
Where does the oil come from in a Chrysler 5L Hemi?
Chrysler included provisions for a “multiple displacement system” (MDS) in the original design, so the main oil galleries were used to supply oil directly to the solenoids that disabled the lifters and the oil for the lifters came down through the pushrods from the rockers up topside.

What is the casting number on a 5.7L HEMI engine?
The “Dee-shaped” exhaust ports on these heads flow about the same as the square ones on earlier heads, but they’re shaped like the ones on the 6.1L SRT heads now. The casting number left bank head is 53021616DE and the right one is 53021616DD casting.
Are there any changes to the GEN III Hemi engine?
The rocker assemblies are about the only two things that carried over from the original Gen III design. While Chrysler made significant changes to the block and heads, there are some evolutionary upgrades also, including bigger valves and ports, updated cams and lifters along with a stronger crank and rods and a high-volume oil pump.
Can you add VVT to a hemi engine?
Adding VVT to the Hemi engine required a new block with had three additional oil passages and an extended front cam bearing that allowed them to supply oil to the cam phaser through the front journal. According to Anderson]
