Hello community,
sorry for the title of the thread
My question is the following:
The ford 302 engine was build from 1961 - 2001.
Up to 1986 the engine was carbureted, then with fuel injection.
Is it right, that the components (attachment parts) are the same for every 302 in every year of construction?
If not, which parts are different?
I mean all parts like water pump, power steering pump, oil pump, starter and so on.

Sorry for my bad english, i am from germany

Thanks for reply,
Martin

 

302 introduced Spring 1968 in FoMoCo Passenger Cars, 1969 F100/Bronco/Econoline.

Last installed in 1996 F150/250, Bronco & Econoline.

 

Ok, produced from 1968 - 1996 ;-)

What does "NO" means?
Wich parts are different (or equals) and in which way?

Thanks,
Martin

 

Some of the heads and block bosses are drilled differently or not there depending on the year, so the auxiliary components, alternator, power steering pumps, smog pumps etc. will mount up differently.

 

There were many changes to the various parts over the years. Too many to list here, So, no they're not all the same. If you want specifics on certain parts, ask away.

 

True, but the 302 lived on in the explorer until the year model 2001, that was the last year. (still sold as a crate engine)

On the earlier one 68 is the start year for the 302, but before it was the 221,260 and 289. The 302 is a stroked version of the 289. The blocks are basically the same just the cylinder skirts are a tad longer.

The 221, 260 and early 289 are a 5 bolt trans bolt pattern, late 289, 302 and 351 use a 6 bolt trans pattern. Ford did a redesign on the bell housing and transmission pattern around that time frame making it wider for vibration/strength purposes.

There are several things to consider with using parts from different years. Roller cam shaft vs non roller, early two piece main seal vs later one piece main seal, 28.8 vs 50 oz balance. Standard rotation water pumps vs reverse rotation water pumps, efi vs carb and even standard rotation vs marine reverse rotation.

 

The engine mount locations and trans bolt pattern never changed and you can put any small block head on any vintage motor but as mentioned there were a ton of changes to various small things over the years. Some of the more significant changes include a change in engine balance in 1981 from 28oz to 50oz and the block became roller ready in 1987, and the heads changed a lot over the years so more pointed questions will get you more details.

 

Roller blocks first appeared in late 1984.

 

Only in Mustangs from what I have seen, the block casting was officially updated to use the factory roller cam setup in '87(E7TE) so you could make a roller motor from any block cast after that even if it didn't originally come with a roller cam.

 

From what I recall the 85 block is an E5AE casting, indicating that it's not a Mustang only casting. I haven't had the opportunity to take one apart so I cannot positively say these were Mustang only castings. Just going by Ford's other uses of other parts over the years, I doubt it was only used in the Stang's. Then there's lots of E6SE castings floating around as well.

 

Yeah there were no car specific castings by the '80s it was more of a global(all platforms) thing by then. I know roller cams turned up in Mustangs before everything else but I'm not sure exactly what components they used to do it, if they were using the common flat tappet block did they modify it to accept the spider assembly(drill and tap the valley) or use link-bar lifters?

 

They used the same parts as the later engines used, dogbones and spyder. The first roller blocks had the taller lifter bosses added to the E0AE casting, then after Ford realized this weak kneed casting wouldn't hold up to the added power, they came up with the 86-up blocks and added 4 more lbs of iron in the decks and bore bottoms. Look up all this in the Official Mustang 5.0 book published by Ford Racing. The E0AE blocks weighed in at 120 lbs, 16 lbs less than the pre 1980 castings. The lifter bosses added 2 lbs. (122)

 

Thank you guys for all the answers
