Anybody know Mustangs? I know, don't flame me.

A '66 Mustang that has the sprint 200 L6. Want to put a 302 from a later model that runs great. Question is:
Can it be done without major frame/suspention adjustment?
I think they threw in the 200 from the Falcon because the 289 was so popular, they were running short. I'm thinking maybe they didn't put the lighter frame and stuff on the Mustang till they found out that engine would actullay sell and therfore, it's built for the 289 that will take a 302. I know this isn't a Jeep thang, but I figured someone might have some insight.

The six cylinder mustangs had 4 lug axles, the V8 cars had 5 lugs. Going to need a 302 with tranny, different motor mounts, bigger radiator. I'd probably put some stiffer coils in up front as well.

The early mustangs and falcons are the same under the skin. No frames, both are unibodys.

Regarding fist generation mustang(641/2-66) V8's:
the 260 was the first v-8 in a mustang, little brother of the 289. Available later were the C code 289 which is a 2bbl, the A code 289 which is a four barrel, and the highly desireable K code 289 which was rated at 271 hp, it had solid lifters, etc...

One thing to look for when swapping early small block ford stuff is that in '65 ford changed the bellhousing from 6 bolts to 5 bolts, or maybe it's other way around, can't remember.

They went from the 5 bolt, to the 6 bolt. the 6 bolt is the more desirable, and is easier to find. I had the "A" type 289 in a 64 Mercury Comet (twin sister of the falcon), and was very happy with it. with a little work, you can pull a very reliable 300+ HP out of it.

The front spindles are interchangable, from the 4 to 5 bolt, so you're ok there, and the springs for the 6 should be ok with the small V8.

Another alternative would be to consider the 250 cubic inch, 7 main bearing six that Ford came out with in '68 or maybe it was '72. Anyway, it would be a bolt in, and in a relatively light car like a '66 Stang you could probably get decent accelleration and milage.
