I really like the '67 Fastback, and hope to acquire one here soon (after the next set of braces). I was wondering what the pros and cons are of owning a 289 versus a 390. The idea of more horsepower appeals to me, but I was wondering if the 390 is harder to work on since it is bigger, and if a 390 is harder to steer because the engine is heavier. Any other info would be appreciated.

 

Yes and yes. The plugs are a b*tch to change since they and the manifolds are all but touching the shock towers. It is a heavy s*cker, too. In stock form the 390's performance was nothing to write home about either.....

Im not really a FE-hater, I just play one on the Internet nah, Im really not, its just that the 390 as-stock doesnt overcome the disadvantages listed above. Just because it was the largest engine option in '67, that doesnt mean it was the best engine

390s can be built to run hard esp with head work, but you will pay big $$$ to get that "S" in the VIN. I recommend you find a C-code (less initial $) and put in whatever engine you desire. Now, if you really want that S-code, by all means, get one and work it over.

I would also suggest the smallblock for a new Mustang owner. FE's are often a big ole PITA. Smallblock engines are must more affordable, maintainable, reliable and economical.

 

Thanks! Your advice has helped a lot. I am a big fan of the 289 anyway, so this looks like a win-win recommendation for me.

 

I agree with these guys. The SB 289 has been a nice engine to work on, parts are affordable and you can get good performance out of them without sacrificing front end weight and road manners.

That said, I'm now ready to start building a 1970 429 engine, and looking for a car to stuff it in... (Sounds like a good topic to start...)

 

I have a 390, and I can't say anything bad about the engine other than it is a boatanchor.

The 390 is an easy engine to work on as well, about as basic as you can get.

If you are going to get a '67 and it does not have an engine, or you want to put something modern in it, how about a carb'd 5.0? You get a roller camshaft with that.

 

And they're, (carb'd 5.0) real easy to work on, Nathan.
