Modern 4.6L v8 to a '67 coupe.

Dave Moors · Feb 22, 2006

Hi all,
Looking for some advice, have been offered an approx 2-3 year old 4.6 V8 and transmission for a reasonable fee, my question is, does anyone know if it would drop into a '67 coupe?
Is it a stunningly brilliant idea that will transform my motoring
or
Will it make little difference to the 289 manual that i have?

If they do what sort of parts are needed as the "extras" as it were? THe trans is attatched to the engine and it comes with ecu and is ready to go as ford sold them to a UK car company for their vehicles b4 they went under. Any common faults problems with the 4.6 modular engine?
Not a oppurtunity that arises often here in the UK so i'd hate to miss out because i didn't ask!
Thanks all.

Not worth the time or the money for the power gain. The only thing you gain is "WOW" factor. That 'reasonable fee' you speak of could probably build you a nice 302 that has more power.

buuying the 4.6 and the trans...you will need...a computer, a fuel system, an intake system (if it doesnt have it already), fuel rails, throttle body, all of the sensors, special headers...the list keeps growing and growing. Be prepared to have $10,000US or so into the swap.

The engine and 6 speed manual is gonna cost around £1800 (around $2900 i guess) which i didnt think was bad, and it has all the bits to make it run included but after i typed this i started to think the headers etc i have won't fit.
Worth a thought, wonder if they will sell me just the trans....................

allcarfan is right, the cost isnt going to be worth the swap, unless you really want something different, and/or have access to 4.6 performance parts, like a blower. the engine will fit between the towers, though barely, and likely you will need a custom set of headers, which wont be cheap either(last time i priced custom headers, i was quoted $700!! and that was 10 years ago). for 1800lbs(sorry i dont have the proper symbol) you can build a very healthy 289 or 302, and still have enough money to put a tremec behind it.

Thats too much for the engine, tranny and accessories. Walk away ....

I'd definitely stay w/pushrod power

Edbert · Feb 22, 2006

I've owned and thoroughly enjoyed two Mustangs with the 4.6 in them. My last car was a 97 Cobra with the 4V heads that I drove daily for 100 months and only chnages oil/brakes/battery the entire time. My current daily driver is a 3V version in the 2005 Mustang. The motors are very nice, smooth, and deliver good reliable power.

BUT...

The 4.6 is larger and heavier than the 460 big block whiile having less displacement than the 289. For powering a classic I'd recomend a carbed 351W, stroked if you want even more power. My classic has a stock-stroked 351W that weighs less than the 289 it replaced

Hmmmmm, it will fit huh ? Thought it needed a MII front end. That changes everything for the next prospective motor then.

I haven't seen this done without at least a strut setup to eliminate the upper control arms so the towers can be scalloped out. Having done a couple of these swaps I'd have to see this to believe it.

Also having done a couple of these swaps, the next two cars I'm building have pushrod engines. Interpret that however you'd like.

I'm not weighing in either way on this (it will fit it wont fit) since I have no personal experience. But it seems most of the swaps I've seen were using the bigger heads, maybe a set of 2V heads will fit

Even if they do fit you'll have to give up on headers unless you do surgery to the shock towers.

NasaGT · Feb 23, 2006

I too have no experience with this, but every mod motor I've ever seen in a classic was a 4v. Those heads are almost twice as big as the 2v heads. I have to wonder if the 2v motor would fit with working the shock towers.

Of course, like mentioned above, the headers would be all kinds of fun.

..the heart of the matter. You would spend a great deal more money and effort to get a 4.6 to approach/equal the oomph of a stroked 302 or 351. Very cool, very "oooh, look at that!," not cost-effective.

But that hasn't stopped a lot of people around here on various projects

If you are still wanting to give it a whirl, contact Dave at www.dvsrestorations.com

..they are 4.6-in-a-classic experts.

Depends on how you look at it. Just for 500 hp, not worth it. But they loooove boost. And a stock Cobra block is able to get a car into the 6's(1/4). EFI, phf. They make a carbed intake for them now. That'll save you a ton of dough.
