Okay, so a friend of mine rolled his HEMI 'Cuda. Too bad for him cause it was a badass ride... but good for me as well. He said he'll sell me the HEMI and trans out of it cheap because it needs a rebuild real soon anyway. But, here's my question. Its the 396 ci HEMI, is there any way it would fit into the engine bay of my 71 240Z? I know I'm going to have to strengthen the chassis because of the torque of the HEMI, but I'm curious if the process is that more involved than with a small block chevy? Also, has anyone ever seen a Z with a HEMI in it before, if so I'd love to see a link. Okay, well thanks in advance.

I have seen a picture of a Hemi in a 240Z, but can't remember what link it was on. I'm sure you would have to use motor plates. Most motor plates are welded to the frame, making it a solid, and rough mount. Competition Engineering makes a motor plate for Hemis with rubber mounts to the frame. Summit Racing has them. If I find the link i'll post it.

I've seen a Hemi in a Z.

The guy had the car painted that ugly pale green, and had the green intake off a hemi sticking out of the hood, exactly like the hemi-cudas had. On the intake, instead of saying hemi-cuda, it said hemi-Z.

I have no idea how th guy did it, but it was a bay load of engine. It was wall to wall power. The guy was saying there was a lot of custom fabrication that had to be done, and he had several 1 cross bars welded between each side of the engine bay, for structral support.

The guy had slips showing 1/4 mile passes in the 10's. Horsepower was evr 400, and I'm sure had enough torque to pass a city block with the tires lit up in every gear.

The guy was a car show in Atlanta, and works for a company that builds 300hp N/A Z engines. I can't even think of the name right off hand. I'll back through my car show slips, and see of I can find a bussiness card or something. I may have a picture in my files, so I'll check today or tommorow.

Good luck with the project.

First Cuda's came with 426ci , 392 was the late 50's version.

The Z in the picture belongs to Kim Taylor's brother.

Hemirode has a early 50's ~289ci hemi from a Desoto.

This engine has a much smaller external dimension then

the 354,392,426 version. Also the 392 long block weighs ~800lb's.

You've got your work cut out for you!

My buddy Nick just ETS'd from Ft Campbell,KY and came out to the Springs to visit his 440 Roadrunner (serious front susp rebuild needed). I had him drive the Datolet. The bug bit him bad, he has several 440's at home. With fenderwell headers it should fit. As my old mentor W.W. Butch Elkins always used to tell me It's Only Metal and Speed Is Expensive, How Fast Did You Want To Spend? We'll keep ya'll posted. mikey

Jesus H...

The 396 (the older hemi, found around '58 I think) is a VAST and HEAVY mother. FWIW, the much more famous hemi (and rightly so) is the much later 426. Lots of differences. The 426 in stock trim around '70 was known to put out well over its rated 425 (gross) HP. Supposedly some were dynoed and they were more like 550. They also have an absolutely brutal amount of torque. :)

Dodge actually made a HEMI Dart in '68 and cranked out about 52 units. It came with a fiberglass front end, swiss cheesed-aluminum seat mounts, no back seat, no carpet, battery in the trunk, pull-down plastic windows, and primer only. This was possibly the most radical thing ever to come out of detroit, (tuned much hotter than even the normal stock hemi and supposedly in the 700+ actual gross HP range from the factory) and would pull mid-TENS in the 1/4 BONE STOCK with slicks. :) :)

Either one in a Z would probably make it an absolute boat. I bet either one weighs nearly twice that of a small block Chevy mill. You'll need some serious weight in the back in order to A) Hook up, and B) Make the weight distribution close to sane.

Good luck!

getting a little non datsun here, but the 392 hemi the guy is talking about is different from the 440 and 426 hemi blocks you are talking about. The 440 also has a much wider head than the 440, making it that much wider to fit into the engine bay. Plus I don't know why anybody would put one of the early hemis in any barracuda, not to mention trying to stuff it into a z. I myself own a 71 cuda, so I have a little experience in the matter. The early hemis are nowhere near as common or desireable. they are hard to get parts for, and a lot of stuff to put it into a z would have to be custom made. That all adds up to a lot of money to get it to work in a z, negating the fact that you cn get the motor for free. a chevy would be just as cheap and faster, but not as different.

Hey GREG, They didn't call the 392 Hemi an Elephant Motor for nothing. I have a 355 SB Chevy in mine. But, Nick is a Chrysler Freak with a 71 .060 over balanced/blueprinted 440 Roadrunner, 72 Barracuda, 76 stepside pickup and too many 440's for his own good. mikey

Yeah, I knew that the 426 was the one in the Cuda. I don't know what I was thinking. Must have been all those exhaust fumes in the cockpit of my 240, hehe. I should be ashamed of myself for messing that one up. Thanks for the info on the DeSoto Hemi. I realise now that the 426 just would not work, but I do need a new motor soon.. Gotta have my mechanic find an old low miles DeSoto MAybe. MMMM, hemi Z, still sounds good.

Re: Oh, yeah, what was I thinking.

My boss just gave me a 302 that he pulled from an old Bronco. I drove this motor for about a month and it was real strong. It has an aluminum intake a 650 Holley carb. He says it has a valve cover leak, but I'm not sure what it is. It comes with the tranny, exhaust manifold and almost everything else (not like you'd need it). I would be willing to let it go for real cheap. I've been thinking of putting it in my '74 260Z, but that wouldn't be cost effective now would it.
I'm in Texas. Let me know. Z ya
