I have and so has my grandfather. Both of our cars averaged over 20+ mpg, and on the hwy with my I6 modified I still got 25+mpg.


Only thing about the V8 swap is you are going to have to redo the entire drivetrain, suspension, steering, and cooling systems.

I like the SVO or BMW solutions, more so the SVO. BMW components are going to be more expensive. Honestly if its going to be your DD for that long of a trip it would probably be a good thing to upgrade the suspension, brakes and steering anyway, so don't throw out a v8 option.

There are kits for t5 swaps for the I6, makes things pretty easy if you want a modernized original.

I have a update and a question. I just purchased a 60's 289 complete engine that had been rebuilt and never ran. I'm going to swap the old 6 with this 289 and keep the 3 sp manual. What all do I need to do?

Don't listen to any Chevy crap, this is a Mustang site, that's a Ford, duh. If you are gunning for mpg and want some power too go with a 2011 up 3.7 V6, take your pick on either the manual or automatic (both 6 speeds). The 3.7 is only 21 inches wide so you can leave the shock towers to help the budget. You can get a salvage 3.7 and trans for 3K or less. You may have to fab a custom engine crossmember, no biggie, the wiring will be the biggest pain in the rear. Buy a factory service manual and read the diagrams. You'll end up with a 13 second, 31 mpg car, or more since you'll weigh about 500 pounds less than a 2011 Mustang.

How about swapping in a 3.7 V6?

The 3.7 V6 swap sounds like a great idea. I have been watching for a salvage or a take out.
