Hi, I own a '66 convertible. I had to overhaul the engine, and when checking the engine code, I found the following : D2OE-6015-AB. It seems to be a 302 from '72 (correct me if I'm wrong).
Google pointed to some discussions, where this code on cilinderheads reffered to a "Police Interceptor".
Does somebody know if this is something special ?
I am still looking for a pair of cilinderheads (one is cracked), so do I go with 302's?
I always supposed it was a 289 engine. When I order other parts, can I go wrong if they're for a 289?

Thanks from a newby.

 

you have a 302 not a 289, ford dropped the 289 at the end of 67 and started using the 302 in 68

 

What parts are you speaking of ordering? Almost every part between the 289 and 302 are interchangeable.

 

It recently got a complete overhaul. The overhaulcompany mesured the cilinders, and told me I had to get .40 oversized pistons (I know, not so good), so I let a mechanic order them.
I just recently learned about enginebloc codes, so now I 'm wondering if the right pistons were delivered.
The overhaulcompany only bored the cilinders once he got the new pistons, so I am sure they fit perfectly, and they seem to come almost to the top of the engine.
What's the difference between a 289 and a 302 ? bore or stroke? And if it is bore, do I have a 302 engine with .40 oversize pistons, or not?

the difference is in the stroke. if you have a D2 block and im assuming the crank that came with that block than you now have a .040 302. for the record .040 is perfectly fine, even .060 is ok in all honesty.

 

Thx,

I got another problem to. When I reassembled the engine, I noticed the cranck and waterpump pulleys touched eachother. When I tried to start the engine, the waterpumppulley sometimes turned the other way. Since this is apparently a put-toghether engine, I measured the pulleys.
Waterpumppulley is 6.1 inches, and the cranckpulley is 6.61 inches wide.
Are the sizes as should be, or do I need to change one or both?

 

there were 289 offering in 68 just for the record

 

Yep, about halfway through the 68 model year, Ford dropped the 289 and added the 302. However, this guy has a 72 model 302.

 

yeah but we're they just using up the rest of the stock when they used the 289 in 68?

on the pulleys i cant help ya other than to say do some boneyard hunting and let yourself end up with "underdrive" pulleys =)

you can search everything from grandma's station wagon to vans and pickups.... different pulleys in different cars from different years on different motors. you'll find a combination that makes you happy.

 

On the 289 in 68 yeah it was just using up what was left. In fact I've seen 302's with a 289 block casting..No biggie.
