It works on all motors be it I6 or V8.
I am not sure were to get one though.
I know Moroso has lots of pulleys.
Or maybe FRPP?Hans ------------------

the accessories will be stealing the same amount they would on a v8 at the same rpmthey should be worth a couple hp or maybe some mpg i'd look into spending money on something with a better hp/dollar gain or savings

If I were you, I'd upgrade that 3 speed tranny to get an OD. That was my biggest gain with the six.

well the pulleys i have are pretty crappy looking. i could get some nice ones and see what happens. mooney what kind of tranny do you have? but ive heard of some problems with charging and such is this true? would it matter what kind of pulleys as long as there the same size or smaller could i use a 289 pulley set? i cant really find an under drve pulley set for a 200ci. i plan on having this motor for a very long time------------------

At the moment I'm running a SROD out of a 79 Mustang. I got an adatper from Fordsix. It's an okay tranny, but the gear ratio between 2nd and third is way too wide. I rev it pretty high and shift to third and it'll still bog down, up till then it pulls great. Nice internal linkage setup. If memory serves though, the 2.77 you've got doesn't have a synchronized first gear, you could also switch to a 3.03 out of a 67 and up mustang (you'd need to get the bell, I wouldn't bother with an adapter) which would be a nice swap but you'd still keep your three speed. The ultimate swap for the six would be the T-5 though, I wasn't able to come across one until I bought the complete driveline out of an 87 LX. But that's a bit more pricy, unless you could fab up some of your own parts. But you'd be able to keep your stock clutch linkage if you used an adapter, you'd need a new crossmember which you could also fab up depending on your welding skills. I'd consider selling my whole SROD setup but the tranny I have is about to kick the bucket so it'd be just a waste of time.. I think in my complete setup.. adapter plate was 110 tranny was 50 clutch setup was 70 from a local clutch place and drive shaft shortened was I think 45. So you're lookin' at close to 300 for the SROD.
Here's a great post for a 4 speed swap info concerning the 6.

EDIT: While I can't recall ever hearing anything good about Clifford Performance.. You could give them a call and ask them about underdrives for your 6[This message has been edited by Mooney (edited 03-20-2004).]

a local mustang place said they would sell me for 700 bucks a three speed tranny (3.03) the bell the driveshaft and yoke good deal or no? would the 2.77 tranny front yoke fit the 3.03? if i found a bell? i dont think that would be a problem------------------

Honestly man, I try to stick away from Mustang suppliers if I can, I've gotten most parts out of a junk yard. And with a lil bit of elbow grease and a can of paint they can come out lookin' good as new. If it were me.. and I had 700 bucks, I'd go for the T-5 swap. The only good thing about the 3.03 was that it was a much stronger tranny and it had a synchronized 1st gear. But still no OD. With the OD I averaged 25 mpg in town. Which is quite nice with todays gas prices.
EDIT: I'm not sure if the 3.03/2.77 yokes are interchangeable. [This message has been edited by Mooney (edited 03-20-2004).]

Somewhere along the line I remember reading.. if you swap for the 3.03.. Make sure you don't have a pre-66 block, for the '67 bellhousing won't bolt up to it.
Best of luck to you on your swap man!

If your blocks a 66 it shouldn't be any different than the 68 you're getting. But even if it is, in 66 Ford went to a dual pattern block. Which was juat the addition of two more holes in the block. So say you have a pre-66 bell, it should work on a 66-up block because the 66 block has the exact patter of a pre-66 just with the addition of two extra holes.
Hope that made sense...

Look at the Moroso 64800 Alt pulley, maybe that one will fit your alternator.
The Moroso 64550 fits all four bolt dampeners, does your have four bolts?
Get an old four bolt pulley from a sbf and see if it fits on your dampener.------------------

i thought the idea of under drive pulleys were smaller pulleys. i looked at the moroso 46800 and this pulley is 5 inch in diameter my alt pulley is 2 3/8s" and the water pump is 5 5/8s" i know the sizes are right but are the pulleys bigger or smaller. hey hans whats sbf? also i like the price for the alt pulley but im not sure on the size so i thoguth the bigger the pulley the less power especially from the alt------------------

With a bigger driven pulley it means the rpm goes down.
The smaller crankshaft pulley slows down everything,the alt pulley only changes the rpm for the alt.
This way you can keep the waterpump rpms.

Yes the output of the alt will decrease some, that is the price you has to pay for lesser drag.
If the cooling system works good now you could try to slow down the water pump as well and see what happens.The main reason for the under drive crankshaft pulley is to slow down the speed of the belt so it does not fly off when you increase the rpm of the motor.
IMHO
