Quick one. I had a read of this thread on another site, not all pictures work but the text is good:


I've been thinking about grabbing a 6.4 out of a Jeep wreck here in Australia and getting it ready just in case my 5.7 cam or lifters decide to die. I'd compression test it, pull the heads off and change the cam and delete MDS. Take the sump off and check bearings out and run it like that eventually.

Just wondering, if I buy a car 6.4 out of an SRT Jeep Cherokee from around the 2017-18 mark, I assume it'd have a port on the intake for the brake booster, unlike one out of a 2500?

Like the above writeup, I assume I'd just have to change the sump, timing cover and water pump off the 5.7?

I'd also line up someone to do the ECU mods for me locally.

I just did a bit more reading and realised the SRT car intake needs swapping out for the 5.7 one anyway.

Also just found new crate 6.4 SRT MDS long motors in Australia for $9500, which is about $US6000. Would be an easy change out for the 5.7 stuff. Only issue is the cam so OEM and so are the lifters. Would be a bit sad to change out a brand new cam and lifters!


They also have new long non MDS 5.7's:
