Ive currently purchased a 68 fastback project car with the suspension completed. Now its on to the engine. My goal is to make this thing haul *** as ihave already completedmy street-friendly 69 coupe.

Which engine you guys think would be more optimal? Money is not a factor as i dont plan on having this thing done anytime soon. I plan to take it slow and enjoy every bit of it. Im looking forward to your responses.

 

Id go 351to a408 and make it go,, go baby go!!

 

go for the 390 look up the fat pig it could be a clone.

 

I looked up the tag on the fastback and it matched...why a 390 ? Just curious.

 

in 1967 there was a mustang with a 390 geared towards high performance and lee Iococa dubbed it the "fat pig".....i'll be home in about 45mins and ill give you the history and the specs on it.

 

lol. Looking forward to it.

 

Mine was supposed to be a 390.. It's not worth it, performance wise.. If you're trying to stay original, (I don't even know if yours IS an s-code?) then give'r if you want, but if you want performance, I agree with the 351 stroked.. Or blown.. I'd say blown, myself. Hell, 5.0 supercharged.. how much horsepower are you looking for?

 

What do you mean "supposed to be" a 390? WAS it a 390 and it wasnt worth it? Or were you "jipped" and it wasnt worth it? i dont understand what your saying.
