302 vs. 289

rfisch · 02-02-2005, 10:38 AM

I recently pulled my 289 out of my '65 to get a lot done to it but I just found a pretty good deal from a friend of mine on a 302 ('67 I think) and was wnodering what the actual differences are. I mean if it's a six bolt to the housing like mine, then will the 289 heads, exhaust manifolds, intake, timing chain cover, water pump, oil pan,... and all of that stuff still bolt right back on? I have been told that they are the same block, just bored different. Is this true?

rfisch · 02-02-2005, 10:46 AM

While I'm at it, what other engines can go in a '65 that was stock with a 289 and an automatic transmission. I would only truxt my welding if it was some furniture or something, not quite good enough for engine mounts yet (lol), so I'm looking more for something that will drop right back in.

Phillyfanfrombirth · 02-02-2005, 12:21 PM

You need to find out what year the other engine is... 302s started in 1968.

Make sure the bellhousings are the same, I forget which year they swapped them to a 6 bolt...

The balancer and crank pulley will probably be different as Ford went to a 4 bolt hook up from a 3 bolt...

The blocks are generally the same... I think that the bore and stroke are both a bit bigger on the 302...

Phillyfanfrombirth · 02-02-2005, 12:26 PM

BTW... its an early Mustang... keep the 289 if at all possible.

rfisch · 02-02-2005, 01:02 PM

Thanks for the info. The reason I was even looking at different engines was because when we pulled mine, the freeze plugs are all pushed out and it looks like there may be a crack in the back of the block. We will have to wait untill its cleaned to know for sure but I think I might be in a little more trouble than I had thought. I'm trying to find a 289 block to drop back in it but my friend was going to give me the 302 cheaper than I can find any 289s right now. If anyone has a 289 block or knows someone whos looking to sell one please let me know. I'm in ohio so anything within a days drive would be great.

When I had my engine work done I asked the guy at the machine shop what it would cost. He said bored and new pistons $425. or he would swap for my core for the same money. I had mine done, it was virgin and the other block was .60 over. They bored mine .30, it had 8 new pistons in it and a new cam, which we removed to put a better one in. The point is, check the machine shop and see what they have, it may be a good source.

rwhite65 · 02-02-2005, 09:52 PM

You can swap all the 289 stuff to the 302. The timing chain cover, water pump, balancer, pulleys...etc. The exhaust will also swap over.
If u were asking what else you can put in there, a 351w will go in, but it is suppose to be a tight fit. Will take different exhaust most likely and I think you may need some different motor mounts to lower the engine in the bay, to clear the hood.

289 to 302 darn near everything will bolt back and forth. They didn't change the balance on the 302 till around 1980.

The main difference between the 289/302 is the stroke. Same bore, but the stroke is longer on the 302 [3 inch]. Bore is the same.

The early 289 had a 5 bolt bellhousing. That was 65 only. But, I'm sure there were some early 66's with them too.

What will fit??? Anything you want to. Depends on how much $$$ you want to spend or how much time you want to spend.

To get it under the hood and not cut the car up the 302 is by far the easiest. You can get a 347 kit for it and really wake it up too.

351W will fit, but it is tight and you run into hood clearance problem.

Good luck.

Devine65GT · 02-05-2005, 09:41 PM

just pulled the 351 out of my 65 a couple months ago, i had a 302 in the garage for a couple yrs, so i had it rebuilt. but anyway the 351 fit in the 65 fine didnt need much work at all only thing we had to change out was the ex manafolds, but everything else is the same. i still got the 289 hi-po in the garage as well. i am in the process of rebuilding that one myself. as far as the 351 and the clearance i didnt have any problems..

Phillyfanfrombirth · 02-05-2005, 11:23 PM

The balancer weight wasn't changed until the 5.0's came along... however, I was speaking of the mount on the balancer, for the pulley. They went from a 3 bolt to a 4 bolt set up in the late 60's...

rwhite65 · 02-06-2005, 11:55 PM

They did switch to a 4 bolt as he said on the front balancer. Since all the front dress is fairly interchangeable...run which ever you have or want too.

Somebody makes those kits, where you switch your front suspension over to the A-arm suspension, i believe, and then they have new sheet metal you can buy, which allows you to cut out your shock towers, and pretty much fit any engine you want in there!! Big money big money big money....................

k. putman · 02-10-2005, 07:42 AM

Both the 289 and 302 have a 4.00 inch bore. And as stated the blocks will interchange.

One difference...the 302 has a deeper bore. Do not read that as longer stroke. The depth on the cylinder wall is longer at the bottom. Why does this matter? For stroker motors there is more skirt support at BDC and thus less piston movement.

Ford measurments for 289 and 302's are 20 3/4 inches tall from pan to valve cover (measured with no intake) and a W is taller at 23 3/4. Width is 18 1/4 inches on the little motors and 21 inches on the W's. They will fit, watch for hood clearence. Back in the day we have put Clevelands in as well with the only problem being some hard to get to plugs.

Gearhead999 · 02-12-2005, 09:50 AM

The 302 does have a longer stroke. That's how they get the extra cubic inches from 289 vs 302. The bores are the same, four inch.

The blocks are different as K putman stated above.

Rev · 02-13-2005, 06:10 PM

I had to have the bottom of the bores notched at the machine shop for adequate clearance for the rods in my 289 block with the 302 crank. The 289 and 302 blocks are not identical from what I understand. It wasn't any big deal, but the notches were necessary to use the 289 block with the 302 crank.

Ingeneius · 02-28-2005, 09:30 AM

I took my 302 in for a rebiuld, the machinist looked at the block, it had D4 as the first couple of letters, he said D stands for the decade, 70's and the 4 stood for the 4th year so 1974 is when the motor was made, I am assuming that C stands for 60's and E stands for 80's.
