Long story short I threw a rod in my 67 coupe(289), found a great deal on a 4.6L V8 and Id love to make it work. Ive heard both sides of this... one saying I need to cut out my shock towers and the other saying it will fit without cutting anything.

So my question to you guys, haha, will it fit without cutting the towers and what all will in need to make it work besides the wiring harness? My car has a 3 speed auto(C4)

you would need to cut the towers + need a new transmission. rebuild the 289

Click to expand...

I would if I could... the block is trashed. So a C4 wont work with a modular 4.6?

The modular 4.6 is a very wide motor. It will probably need mods to the fuel system like pumps, return lines, etc., not to mention the computer, blah, blah, blah...

That's why they call it "dope"

The payoff simply isn't worth it unless your getting a motor in really good shape for nearly free. Even then it's iffy.

The only reason for this swap is "to be different" but it's been done many times now already so you wouldn't even be all that different...

buy a roller 302 and put your intake and exhaust on it. save you hassle. the 4.6 2V isn't an awesome motor by itself

I'm putting a 4.6 dohc in my 67 coupe. I'm using the complete drivetrain from a 2003 Cobra. The DOHC is wider than the 2V but they are both very wide. I wouldn't do this swap again. If I had used a 351 based stroker it would cost less and I would probably have the car finished by now.
