    2006 5.7L cam swap

    Is it possible to swap the cams on a 2006 5.7L hemi without pulling the heads?? I thought I read an article somewhere where they clocked the cam to push the lifters up then removed the cam out the front like usual. Anybody have any input??

    I haven’t personally done it.. but have seen talks and videos of people removing the valve covers, removing rocker arms and push rods. Then removing timing cover and all that and spinning the cam a few times to push the lifters up into their bores then quickly trying to install new cam

    You can but if the car has a lot of miles on the clock it would be a good idea to pull the heads and replace the lifters with Hellcats.

    Looking At my lifters from my recent repair, it does not appear they failed per say, but more had spun so many damn times the needle bearings wore down to nothing causing excessive play in the rollers. Mine had 145K and 2 whiped lobes with another 2 lifters about to do the same. If you have high mileage would deff do new lifters

    Yes, you need to use magnets down pushrod holes that magnetize lifters to bore.
    Done it at least a dozen times. Used cheap pencil sized extendable pick up tools from Autozone. Just taped the extended up to keep them from hanging up and pulling all way out when you are done. Happened the first time, then taped and all was good

    No need for anything fancy. The lifters get held by the guide. Just rotate the cam a few times and they will be pushed out of the way.

    Johan suggested the 274 cam and said he has tunes for it. Soooooooooo, I'm going to do an MDS delete, change valve springs and pushrods. Short of pulling the heads, can I use the OEM lifters with all these head mods??

    Depends on the year of the engine. The pre Eagle engine would use the 273 while the Eagle engines use the 274.

    That's what I was thinking when I was reading about the cams. The 274 uses the VVT and I know mine doesn't have it but I thought maybe Comp made a 274 for my old 06. Lol

    No the Comp 274 is only for the Eagle 09+ Hemi's It won't even fit into the engine. For lifters YES you will want to use OEM. The current revision of the Hemi lifter is the Hellcat lifter. Anyone swapping cams is using them. They are what will be going into my engine this weekend. They are around $360.00 for a complete set from eastcoastmoparts.com . For springs you will want PSI 1511's and you can use MOPAR 6.1 SRT pushrods they are $70 for a complete set also from eastcoast. It will be a lot easier to swap springs,retainers and valve seals with the heads off the engine since they have to come off anyways.

    Yes it can be done without pulling heads,, Ive done it on new replacement engines. Not sure I would be very comfortable doing it on a engine with over 60k on it though. The lifter sit in the holding yoke pretty well after rotating the came a few times with the rockers and pushrods removed due to the more horizontal angle of the lifter bore (compared to most other engines) .
