V8 Engine Mount Brackets?

I'm swapping a 5.2 engine/trans from a 94 Dodge pickup into a 93 former 4.0. I'm looking at pictures of V8 ZJ motor mounts and they're not looking like they'll bolt onto the ZJ body. Not having a V8 ZJ available for examining, I'm guessing that there is some sort of bracket that goes between the motor mount and body. If so, what's it called and where do I find them outside of a junkyard. V8 ZJs seem to be scarce around here.

Yeah. You need a motor mount on the motor side with the bushing in it and a frame mount for the frame side that the motor mount bolts into. Other than a junkyard or e-bay I have no idea where to get one. Maybe try and find someone parting a V-8 ZJ on craigslist?

edit: Just did a quick search and came up with this. Not even sure it's off a ZJ but looks like it could be and will give you an idea of the frame mount.

They're different for each side.

Salvage is about the only way to go on these.

Hope you have a jeep transmission and exhaust manifolds to go in.
The dodge stuff is a huge pain to make work(and the exhaust manifolds from the truck absolutely won't work)

I'm using the whole Dodge drivetrain sans axles. So, I'll need to scrounge engine mount brackets and manifolds. I could probably find the manifolds on Ebay. The engine mount brackets aren't so easy.

Nope, you'll be buying headers if you intend to use the dodge transmission. No stock manifolds work for that.
I've got a dodge transmission in mine. Check the links in my signature for info.

You'll be building custom exhaust and a transmission crossmember. Custom x case shifter too.

The pickup trans is a 46RH. Is that so much different than a Jeep 46RH that the Jeep manifolds won't work?

This is a racing Jeep it won't be streetable anyway. We have to use factory manifolds to stay in class. The crossmember, t-case shifter, and exhaust pipes aren't a big concern. We planned on fabbing that stuff anyway.

Our 4.0 lost last years 2nd place season point standing to a 350 Chevy by .2 of a second.

Well I have a set of 318 5.2 headers from a 96 or 97 if your needing them.they are very similar only difference is the egr pipe which is included. You would need the gasket for the egr pipe as this was messed up when the enginevwas removed. Can be ordered at NAPA locally.

Yep, they're vastly different bell housings it's all because of the starter.

Jeep manifolds dump right into the starter and dodge manifolds run into the firewall.

There's no rule against cutting the firewall. In your estimation, will the truck manifolds clear the, (for lack of better term) frame rails?

Block huggers are out of the question? You could try finding a 46rh out of a Jeep. They're a little harder to find, but not impossible. It'd probably make life a lot easier.

Must have OEM Mopar P/N.

We've been watching out for a V8 ZJ for seven months. The crushers came through and crushed everything. We found a good running Dodge pickup cheap so I thought we'd go with that. It looks like we still need to find a V8 ZJ for parts.

I don't suppose Durango manifolds would work either.

Thank you for the replies. You saved us some headaches.

Bare Minimum OBDII Wiring.

My grandson and I swapped a 98 ZJ 5.2/re44 into his 4.0 racing ZJ. I need the OBD2 to run and I don't know anything about it.

We have the engine wired from the PCM.

I'm retaining the diagnostic plug and instrument panel.

Are there any other special modules I need to retain?

Is in necessary to wire the trans if he can manual shift 1-2-R?
