    4.6 Swap into 68 Deville

    Anyone ever attempted a swap like this? Pros? Cons? This swap has been proposed to me by a relative and I am considering it. Trying to get a little research in. Any input appreciated.

    Assuming your talking a N*, you'd need a RWD version and stand alone PCM. Bet it could be done but you'd better be handy at fabrication, welding and the lot as it'd require a fair share.
    I'd see what could be done to bump up the torque and what trans mods would be needed as you'll be increasing weight by close to 1k.
    Provided you could get donor car complete on the cheap it'd be worth a shot.

    Pros - none.

    Cons - many.

    It's a 279 c.i. high-winding engine - it needs to RUN to get any torque/power - and is really too small to haul around an old Deville. Yes, complete standalone engine management system. The engine is a bit smaller than a 1962 283 Chevy!!

    There are good, valid reasons why the old Devilles came with powerhouse (torque) engines ike the 429 and 472. These cars demand torque, power, and chrome.

    Find a decent late 60s/early 70s big block Cadillac and turn it into a powerhouse - parts are available, while a Northstar is left in the dust as far as aftermarket bolt-on "speed parts". You might talk to the Northstar guys at CHRfab to see if they offer any hope. Bring money, and their engines are primarily for sand rails, kit cars, and Fieros - light weight stuff, which is ideal for the Northstar.

    Here's a pre-2000 built Northstar - hand fabricated - in a '32 Ford Vicky. The entire vehicle/powertrain weighs less than 1/3 of the '68 Deville. Courtesy of CF member Speedygman.

    Tempting, isn't it ?

    Just to add a little fuel to your train of thought, check out some of these pics also:

    It's not gonna be done like a chevy 350 swap, but with enough money, tools, time, and handy-ness, it should be possible.
