Hi newbie here,

dim question time.

I hear 302 & 5.0 mentioned in the same sentence sometimes.

Are they one and the same or, are they not.

Confusedley, Alex

EBXR

Yes, they are the same basic design, with some parts interchangable.

302 is generally seen as the carby version; whilst the 5.0 is generally seen as the fuel injected version.

I bought some 5.0 heads for my 302, so I can run ULP fuel. And they just bolt on. 5.0 has a few extra goodies, like a roller cam, that can be retrofitted in to a 302.

By the way, welcome to Ford Forums!

I agree with EBXR just dont confuse the 302windsor with the 302cleveland which is a destroked 351 made for the Aussie market

EB 5.6

i do believe the 302 and the 5 L are the same. The 302 back in the carby days was also knowna 4.9 L but when they made the injected 302 i think they just wanted to market it as a 5L to go up against the holden 5 L also as the ford 5L is actually 4942 cc's. i am sure the 302 and the 5L are the same, pls correct me anyone if i am wrong.

Cheers big ears

I thought it had more to do with australia changing from imperial to a metric system in the 70'S and like all car/bike makers round it off for us simple folk.
even holden round there no.s up

EB 5.6

they might of been it as well, but if you look on say a xc cobra you will see they are 302's but got a 4.9 L sticker on the air filter. I am sure there is no difference from a 302 to a 5L, they are the same. but i agree the 302 clevo is a smaller 351 made for the aussie market as the 302 clevo and 351 clevo are the same block and bore size, just a different stroke, thats why its had to tell just by looking at them the difference between a 302 and 351 clevo

about the metric imperial thing it was abig thing back then it would have confused a lot of people as it changed money weight speed limits ...... and it may have been fords way of helping people the change over to the new system.
5.0 sounds nicer than 4.9
I think just about any part can be used on any windsor 1962-2003 but there is a small few changes ford made over 40 years
They most crittical change they did was engine balancing going from a 28oz harmonic balancer to a 50oz balancer due to heavier conrods which must be taken into account when mixing parts
Balancing the crank will sort it out though!
I just recently bought a fuel injection setup off a 93 5.0 falcon which im planning on bolting to my 1970 302 motor which im building at the moment

EB 5.6

sounds awsome, make sure you put in a post when its finished with the other mods you have done, i would love to see what rwkw you get out of it. myself i am doing a 5.6L stroker for my ed xr8.

Are you sure about this, the rods are nearly identical from 69-96 as I am using 96 rods in a 69 block.
The counter weights on the crank changed in 85 (roller cam), that is when they changed to a 50oz balancer.

Flex plate/flywheel and harmonic balancer are the important ones to watch out for; pre 85 had 28oz balancer.
Earlier engines 289HP and 302 Boss used a heavier harmonic balancer for the heavier rods used, but it was still 28oz counter balanced

Sorry i should of been more clearer
dont mix 28-once and 50 once flexplate/flywheel -crank-harmonic balancer assemblys as you will have serious balancing problems and will cost big $.
Keep these 3 parts the same and they can go in any block.
The rods are pretty much identical (same forging no. C80E) except for the caps which are thicker . and heavier
the flexplate/flywheel-crank-balancer must be balanced as a set with the rods and pistons you are going to use.Ford changed to a 50-ounce offset balance as there rods got heavier.
the offset balance is for dynamic balancing
A heavier balancer helps dampen combustion pulse shock and helps a crank last longer
289Hp and 302 boss rods have the same forging no.s(C3AE) as as standard 63-67 289 rods except used a 3/8 bolt instead of 5/16.
Any good engine rebuild gets a Dynamic balancing
