hey everyone, this is my first post and i had a few questions. Now before I get flogged for not searching the forum I want to point out that I have searched the forum for hours now and still cant get the exact info Im after, so here goes. I am looking into buying a 1965 or 66 mustang that has the 289 in it. I realize the 289 would be fine but I want to do the 302 swap for sure. My question is what would be involved with swapping the 302 in place of the original 289 car. also, what are all the parts that i would need, ie headers, motor mounts etc? again sorry for asking you guys im sure you get asked these questions a lot. thatnks again!
Well it all depends what you want to do and how much you wanna spend. I just did a 66 302 swap. You should have a c-4? so the bell housing should mate right up. I went with Heddman headers, had to replace all the exhaust. 289 lifts right out and 302 bolts right up to the motor mounts. I have a whole list of stuuf and receipts for cost. Just let me know what you need.

First I'd ask why you want to swap the 289 for a 302. 13 cubic inches isn't going to make that difference. The 289 can be just as good a performer as a 302. Now if you're just swapping out a tired motor for a better one, its basically a straight swap, UNLESS your 289 is an old 5 bolt pattern. All newer (ie. mid late 65 on) 289s and all 302s use a 6 bolt pattern to mate to the tranny bellhousing. If your tranny and block are the 5 bolt pattern, you will also have to get a new 6 bolt bellhousing.
ok thanks guys...in response to 65ehCode, id like to swap the 289 out because 1 I have a nice 302 and 2 the 289 in the car is pretty tired. so i figured if the swap wasnt hard, which it doesnt sound like it is, ill just do it. So anyway the way I understand it is that the 302 will bolt right up to the 289 motor mounts? is that right? thanks again guys fr the great and super quick advice!
Like 65ecCode said, the biggest thing you have to worry about is the mounting flange for the bell housing. The other thing you need to worry about is what year 302 you have. After 1978 the 302 installed in Ford cars had a rear sump oil pan, so the location of the dipstick moved from the front timing cover on pre-'78 cars to the side of the block on post-'78 cars. It's an easy fix by just using the timing cover and oil pan from your 289 and using it on your 302. But otherwise it's a straight up remove the old and in with the new.
EDIT: Oh, another thing you need to worry about... If your car is an manual transmission, the early 'stangs use an equalizer bar than mounts in a boss on the side of the engine. Later 302 blocks do not have that boss, so you might neet to convert the clutch over to a cable linkage, but I believe I've seen a bracket that bolts to the side of the engine so you can use the old style equalizer bar setup with a newer block.

I had this oil pan problem, make sure you clean your 289 really really good, get some cork gaskets and gasket schalak, also you will need the oil pick-up form the 289 beacuse if the 302 has rear sump, the pick-up is the extra longer. easy switch though! also I believe after 78 you will need a flex hose for the lower radiator hose, cause the water pump is potioned diferrently.
Also check you clearance on the timing cover with the fuel pump concentric. The early 289s had a different thickness, when improperly matched will grind a hole in the back of the timing cover.FYI

I'm with 65ehcode on wondering why you would wanna swap it. But hey, I'm not gonna argue this. Anyway, from the outside of the motor, the 302 and 289 are identical(just a different stroke on the inside) so it will bolt right up. And anything that was on the 289 will work on the 302 and vice-versa except anything in the lower-end of the block, and all the other little things mentioned in this thread.

I think that the reasons given for wanting to swap are valid ones. I was only concerned he might have thought 302s were in some way inherently better than 289s. Others have given good advice, just wanted to mention that some 289 heads have smaller accessory holes (3/8" ??), so you may have to enlarge the holes on some of your brackets to fit the larger bolt/studs used on the 302 head. As for the water pump outlets, if they are different I would change the pump to avoid using a flex hose JMHO.
Yeah, I think his reasons are valid too. But I also agree, if he thinks the 302 will outrun the 289, he is sorely wrong. But hey, if he's got a fresh 302 laying around, hey, that's a cheap swap.
