mostly the same

differences were major when they went to the EFI and roller cam. some truck s have different oil pans ...79 fox and later have double hump oil pans and pump pick up tubes changes Efi don't have the casting for the fuel pump or internal fuel pump cam but can be modified.

Other then the Double hump oil pan, and the casting for the fuel pump, what would be visually different between the two (in carb form)? I heard the thermostat neck is different... ?
thanks again

Could you start with a 289 block and build a 347?

why not a 351 W

The 351 windsor is taller and wider, why not start with one and if you want a 392 or 427 stroker? they will fit in most places a 289 will go

I think the Thermo-rad hose neck depends in what it was installed in.

My understanding is that the early 260/289 had a different bolt pattern than the 302.....not sure when it changed, probably 68 when the 302 came out.. Had a friend who put a 302 in place of a 260......had to change tranny too. wouldn't bolt up.

The 260/289 had a 5 bolt pattern until about late '64 and then they went to the standard 6 bolt.

Pre 65-66 Ford 289's had different valve covers, 63-64 289's had road draft valve covers no pvc, the oil fill was in the timing cover, oil bath air cleaners, generators. This is for a common two or four barrel 289 , the HP's had different exhaust manifolds, and I think the valve covers were gold on the HP's. This is just external differences as there are a bunch of internal differences between HP 289's regular 289's and 302's.

Well, I would assume that 302 parts would be less expensive then harder to find 289 parts. I've read that they have thicker castings as-well. I'll be using after market headers,intake,carb,dist,70's 4 spd 9''. I just wanted to be able to get parts easy without searching and have the " look" of a 289. I like the sound of those classic gold valve covers. I'm sure someone who really knows there stuff could tell the difference but like the 350 can be dressed like a 305 or visa versa. Unless It is just as cost effective to build a 289 that can take just as much thumping without worry as the 5.0L

thanks again

If you are going for looks, it will be alot easier to find a rebuildable 302 and use the 289 valve covers .
You'll be asking an awful lot to get a reliable 450 hp 289, that looks like a stock 289.

Unless you start looking at block numbers, externally a 302 block and heads looks so much like a 65-67 289, that they are indistinguishable from each other. I don't know for sure, but think that the short 289 valve covers will clear big rockers and polylocks.

A 5.0 is where things start changing externally, and the dual sump pans and weird waternecks to clear the serpentine accessory drives come into the picture. Although dual sump pans were used on 302's in broncos.

Later, mikey
