I drove a car with a 60's 289 (non HP) for several years. It's a great
engine. Easy to work on and bulletproof. But it certainly is not a
scooby-doo WRX STI killer. If you build it up before you shoehorn it in,
it could be though. And the 289 can do it without 15 pounds of boost like
the scooby. Just trying to prevent an embarrassing defeat for the blue
OP: I would love to see a website with a few photos once you get semi-
289s are great little engines. They can rev all day long. There are people
who build 289s that rev to 10 grand, and live with 10 grand shifts all
A stock 289 bottom end should be safe to about 7 grand, then slap on a pair
of aftermarket aluminum heads (I've heard the AFR 165s are good, maybe the
205s if you wanna have it rev out the wazoo). Then top it off with a good
intake, the Stealth is good to about 6.5-7 grand, go single plane for more
top end. And of course pick a cam appropriate to the RPM range of the rest
of your combination.
The biggest bottleneck on a small block Ford is the heads, so keep that in
mind when doing your build.
Shayne, how dare you use foul language on the forum? - lol.
Good luck on your rebuild. I have always had a love/hate thing with the
Pinto but never Man enough to actually go out and buy one I guess.
The C6 in the part number indicates that 1966 was the first
year it was used, and they switched over to all 302's in,
umm, was it '69 (?). That should narrow it down a bit.
Good luck on the Pinto. I saw it done once, the guy turned
the exhaust manifolds upside down and switched sides to
make it fit. Or maybe you can cut into the shock towers.
Be judicious with the throttle, as the stock diff wasn't
designed for anywhere near that much torque.
Standard rearend was actually a 6.5.... This conversion will probably
take some time to finish, as money and work are constantly getting in
my way. At least I finally have a powerplant to work with!
I guess I'll be looking for a C-4 to replace my C-3, a better rear,
ignition system, etc...
Naturally, photos will be required!
Thanx to all, though, for the assist, hints and ideas!

One limiting factor on transmissions on 289's is whether the
block is 5 or 6 bolt for the bell housing pattern. The
early production was 5 bolts. If your block is a C6 p/n, it
should be 6 bolt allowing you to use any late small block
trans. For the 289, the C4 is probably preferable because
of the upgrades available.
What diff did they use in the Mustang II? Just thinking
out loud, you would have to check, but could it be a
C4 was a pretty good trans with lots of good aftermarket
goodies available. Be sure to get a good intermediate
band, as repeated full-power shifts can peel the lining,
especially if you have beefed the engine. I turned a
couple of C4's into 2-speeds that way back in the day ;-)
IIRC, the HEI systems from later 302's are nearly a drop-in
replacement with not much wiring.
