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 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.

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.
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.

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?
