    Alterkation will defintly make it easier. Then you'll need:

    Custom Headers
    Big Block Tranny
    Bigger Rearend
    Bigger Radiator
    Probably some inner fender Tweaking
    Custom Driveshaft
    Torque Converter
    I'm missing a bunch, but that will give you a reason to start saving money and working overtime.

    You should call Bill at Reilly Motorsports and talk w/ him about his front end.

    $50,000 should get the job done. I think that's more than a wallet full.

    That's an understatement, It's going to need A LOT of tweaking. I barely have room for my smallblock.

    first thing you might want to do is measure the 426 at it's widest point. second measure across the engine bay between the shock towers. if i recall correctly the 66 and older "A"s are 2" narrower then the 67 up ones and the 426 was REAL tight in those.

    I'm thinking 3G 426 Hemi would be easier if not exactly cheaper.

    Basically, take the fenders and hood off, cut off the front frames at the fire wall, and reconstruct out of square tubing, using a rack and pinion and struts. Then re-mount the fenders. You'll still need a hood.

    Don't even bother measuring it, it physically won't fit between the original fenderwells, it will need major modifications.


    Here is my smallblock to show you how tight it is, and I do have to lift the engine to remove the header, my blower belt is also within 3/4" of the radiator.

    Actually the years are 67 and older or 68 and newer,I found out while building a Hemi Dart about 19 years ago that the 1967 shock towers had to be moved back to accomodate a Hemi. The 68 and later are a smidge wider. You still cant get your hand between the valve cover and the fenderwell on 68 and ups. I still have an offset brake block if you need one to move that master cylinder.

    I put a few Hemis in the 67 and up A bodies (no AlterKation, but my own custom K-frame)......everything under a stock flat hood,column shift automatics,4 and 5 speeds, A/C.....all without any sheetmetal modifications....and it's tight.

    the older ones ....66 and older...being a bit narrower....be prepared to do some surgury....and ruin any resemblence of a stock install.

    but as they say...if you got enough money...you could put a helicopter motor in a submarine

    No, 67 and newer are the same, 66 and older are almost 3" narrower

    I agree, I seen how much work a local guy did to his 69 Cuda to make a 426 fit, and the 65 is about 3" narrower than the 69

    There's no way I'd want the stock suspension or brakes with that thing over the wheels. Cut it off, make a new one...

    Blownfish, first let me say I love your car ! I built a 65 440 Bcuda with fenderwell headers. Had to tip out the right shocktower a bit. It worked out well. The petty car was all cut up, firewall moved back etc. The link I posted is about a replica of the Petty car. It was built on a budget and no major surgery was done to it except the pass fenderwell/ shock tower. Take a minute to read it. I asked about a hemi in an early A maybe a year ago and someone posted that link. When I start squeezing it in I will post some pics.

    The problem is you can't just cut the one fenderwell and offset the engine that far to the right of the car, it will need to be more centered up than that, the original engine is offset, but the Hemi is just too heavy to be offset that far, you'll end up with steering problems and suspension problems.

    I know the one in the link is a clone, and it looks very butchered up under the hood, he also spaced the k-frame from the frame rails to give more space under the hood and over the steering box.

    I just think if you are basing your transplant on that car, you'll end up with a lot of headaches and a butchered car when your done. I'm not saying it can't be done, but to do it correctly, you are going to be doing a lot more work that you are anticipating, and I don't see the point in taking short cuts that will come back to haunt you later in the build.
