5.7L HEMI in a Pre-67 A-Body

5.7L HEMI in a Pre-67 A-Body - 03/24/11 02:42 AM

Has anyone installed a 5.7 HEMI in a pre-67 A-Body or heard of it. I know TTi doesn't provide the engine mounts, nor do they provide the headers online. However, Reilly Motorsport provides the motor mounts for their alterktion kit.

Maybe TTi just needs a test car to engineer the headers and motor mounts?

can't tell you much about it but here is a dart with a 5.7 in it. he used stock exhaust manifolds. he did move the PB setup over and used a wiring harness from hotwire auto, he made a sump into the stock tank to mount the fuel pump.
he says its faster than the built 360 he had in it before and get over 20mpg's

he has a cool hood on it.
he graphed a 70 road runner bulge hood to the dart hood

Cool. How much over 20 mpgs? Because an 07 Charger gets around 17st/25hwy mpgs and that has to be at the very least 500lbs heavier than an early Dart.

he has a 4 speed auto(518)Had it in the car with the 360. not the 5 speed auto in the dodge trucks, he is talking about putting a Kiesler 5 speed in it

that should be fun...

I see that is out of a truck with the intake on the side and accessories like a truck. Is that preferable over a car 5.7 for fitment?

I think it would make a fun daily driver.

I believe so, IIRC accessories like the alternator for example is mounted up top as a traditional 60's-70's engine and the car 5.7 hemi is mounted way near the bottom. Possibly causing a clearance issue but don't quote me on that.

True but unless you are going to use a six speed, or a the 5 speed auto your not going to get better then the charger MPG

Ok, so if someone were to use an A-Body 904 or 727, then they are going to lose mpgs compared to (as you said) an automatic 5-speed or a Keisler 6-Speed?

I would also assume rear gears plays a tole in it. Obviously having 3.91 in the back is going to give you less mpgs then the 3.23's, right?

WOW, that is a clean installation. I'm very impressed!

I would have bet a lot of money that stock exhaust manifolds would not fit.

Yes MuMu, big number rear axle gears jack up engine rpms without having overdrive in the trans. Higher rpms turns real quick into lower MPGs... Overdrive is the ticket to high performance and better MPGs both at the same time. Trick is to make everything fit.

So just curious, would an engine and trans package like in the craiglist link bellow have trouble fitting? Do you think there is gonna be a lot of modifications? I know motor mounts and headers would have to be fabricated, and mentioned above about some of the mounting brackets for a/c and such.

Because I was thinking, since pre-67 A-Bodies seem to be one of the lightest mopars. And the 5.7L HEMI gets decent gas mileage for being in a 4000lb car (like a Charger). Then wouldn't it be somewhat practical and fun to have a cool driver with over 300hp and well over 20mpgs in an A-Body? I mean if the engine and transmission combo in a 2007 Charger gets 17str/25hwy, then a 65 Dodge Dart or Barracuda (in theory) should get at least maybe 20str/28hwy? I even heard some stories of some guys that have a 5.7 in 67-69 Darts getting 28mpgs (I am not sure if they had a manual trans, I think one was an auto).

If I were to get a perfectly sound and restored pre-67 A-Body, I think it would be worth it. But if I get a project, then I think I might as well should buy a newer used car.

Idk, I am just thinking about it. Seems like a fun project (to learn with) and car to have driving every day. I have a feeling (after college when I have a job) I am going to be one of those people who have to drive in Los Angeles traffic day in and day out and I don't think my manual transmission in my 2011 Scion tc and my feet will like each other after a while.

Do pre-67 A-Bodies even have A/C? That's a big must for CA!

Question is how much "shaving" is necessary to get the new transmission in the old body with keeping the original t-mount/ trans crossmember setup...I would like to do this to an e body as well. Has anyone did the swap and use the new trans while keeping the original suspension/crossmember stuff? What was needed to make it work??

Yeah, just something along the lines as a budget build. Stock interior, upgraded suspension, disk brakes. I am just curious, does an A-Body 8 3/4 rear end fit in like a 63-66 A-Body?

Its more of the fact that with more gears you keep the engine in it torque curve where your engine will get the must MPG as you accelerate to your crusing speed, also the overdrive helps alot once your reach your crusing speed.

Will an A-body 8 3/4 even fit in a pre-67 A-body? Would there be that much of a difference in model years?

Re: 5.7L HEMI in a Pre-67 A-Body - 03/26/11 01:01 AM

8.75 rears first became available in '65 A bodies, IIRC, definitely available in '66 A bodies. Would usually be found in stick shift cars or severe duty (taxi, police, commercial fleet) cars. So 8.75's will fit, may have to cut a bigger body one down if you can't find a OE '65/66 axle.

So something like a Dodge Dart "Charger" would probably have it because of its 273-4bbl?

Re: 5.7L HEMI in a Pre-67 A-Body - 03/26/11 01:23 AM

Yes, a Dart Charger should have one. I think later production '65 Barracuda's had them available, while '64.5 and early '65 Barracudas did not.

Major differences, which is why he asked about PRE 67 A bodies.

As for the A body 83/4, if you find on in any year A body it will fit. The rear stayed the same in the later A's, only the front track widened but it was essentially in the frame and K member, the rest of the front is the same.

The specs on the Charger R/T show it to weigh upwards of 4200 lbs. An early A body with a 273 is in the 2700 range. The HEMI would probably raise it to the 2850 range with the additional girth, wiring and such. 1350 lbs of savings? Not too shabby!

If you want the 545-RFE your best bet is probably to run the Alterkation K so you lose the T bars, then cutting the rear crossmember isn't a problem...

I'm in the process right now!64 Dart,using RMS front suspension,Modern Muscle's wiring and computer,I modified the trans tunnel for 518 trans,any questions let me know!

Cool! Great! I will if I ever get to that project. The only thing is that RMS can get expensive if you decide to go all then way around the car. I am sure it will give you much less of a headache but I was just thinking of like a complete budget daily driver build. Something along the lines of making new mounts, upgrading the suspension, getting better disc breaks, 518 trans to handle Los Angeles traffic, etc. There is going to be a lot of fabrication, but I am sure that would be much cheaper then going with RMS. Anyway, that will be for much later (if I even get to it, have the money, and find a good enough car). I have a stick shift right now and if I have to drive in LA traffic to go to graduate school or for my job in the future, my feet will not be happy with me.

I already have a 68 Dart project right now and I am thinking about 6.1L with a 5 or 6-speed and an 8 3/4 with somewhere around 3.55-4.10 gears all under an RMS suspension. It is going to be pricey, but I think I am just going to try to elongate the project as much as possible so it will not be too big of a financial burden. Ideally I want to work on the car by myself as much as possible as a learning experience and to lower the costs of labor rather than having my mechanic doing it and not knowing or learning anything about my car.
