How hard will it be to put a 351W into a 67 coupe. What considerations are there. What do i need to keep in mind

No it is easy, just make sure you repair/replace/upgrade things like tranny, suspension, brakes, rear, and cooling system to match up to your power levels. If it was a v8 car originally and all you are putting in is a stockish 351w just make sure everything is in good working order. After that you can consider updates/upgrades as appropriate to meet your driving needs/performance goals.

She'll slide right in, but with any transplant you will need to make some adjustments.

Depends on what was in the 67 in the first place. The motor mounts are different and are not interchangeable with any other year.

It does fit just fine, I have a 351W in my 67. It is a lot larger engine than a 302 or 289 though. You don't appreciate how much bigger until they are side by side on the garage floor.

Nope. The 351 is like a 289/302, only with a taller deck (longer stroke), therefore making it taller AND wider . The wider is what is most concerned with when putting it into something pre 1969. With a 1967 it shouldn't be too much trouble at all, but spark plugs might prove a small challenge, but nothing like a 65/66.

Not a problem at all - plenty of room. With a taller deck though, you need to be careful what intake manifold you use if you have a stock hood. If you get a tall intake manifold, then the air cleaner may hit the hood. Shelby-style hoods help here...
