Thats right some of these came from the factory as a carbed version rather than the usaul EFI.
Has anyone experimented with one of these to see what happens with better carb and extraction. Are they the same block and mounting points and bell housing as the earlier Crossflow engines. Do they have any advantage over the crossflow and did Honda design the head as they did with the Crossflow?
Cheers
 
Gidday Tim, are you sure that it is carbed .I get a lot of enquiries at work for EA falcon head gaskets sets and the customers say its carbed but they allways turn out to be the centre point injection that looks like a carb.The stockcar guys over hear use the 3.9 with a holley two barrell with very good results .

cheers DAVE
 
Sorry fellas, your probably right. I was currious if one of these would go in my TD Cortina with too much trouble, I like the idea of overhead cam and no pushrods with a carb
 
Talk at once to gm destroya, he's got the EA thang sowed up.

The stock CFI has a Weber-carb based bolt pattern for its pi$$ and dribble injection system. 120 KW, 335 NM stock, not ab ad thing at all, as long as you check the head bolts and are able to budget preventiative work on redoing the haed gasket, or set aside some dosh in case it becomes a problem.

There is an EFI control unit, which is a little box in the kick pannel on the passengers side. If you can follow a wiring diagram, and network with the guys here, then you can do it easily. The space issue is nothing, the EA ran a much lower bonnet line, then engine is much shallower with an engines deck height 6.3 mm lower. The Cortina should have enough room for the OHC to fit if you can find the right sort of serpentine drive or radiator.
 
it's a common misconception and that the 3.9 EA had a carby option. the 3.9L never came out with a carb - it came out with throttle body injection which could be mistaken for a carby. you could take it off and fit a carby but i dont know why u would bother - a carby would never metre the fuel as well. you would also be wiring in an ECU just to drive the distributor. you could avoid this by changing the distibutor removing the engine management which in my opinion defeats the purpose of fiddling with one of these engine in the first place.

the blocks are different to a earlier crossflow, the deckheight is shallower but overall length is longer. the engine mounts are roughly in the same place but of a different bolt pattern.the block is also wider at the mountings. the bellhousing mounts are different as they have 6 bolts in the upper half of the bellhousing as opposed to 4 in the earlier blocks. as far as advantages go(the list is long) the main being they are lighter, have a lower specific heat ratio(handle heat better) and they have an extra 20 years of technology thrown in.

hope that helps, any questions gimme a buzz. there probably isnt much that i havent figured out about these engines already - thats my TD with the ED XR6 engine.
 
it could be done. i've seen an ef inlet manifold married to a 250 alloy head. it would take a bit of mucking around?

would it be of any benefit to what exactly? if u were to use the injection and use a later model distributor it'd be of benefit but if u only wanted to do it to use a carby then i'd recommend using an aftermarket performance manifold. although if u were going to go to the trouble of wiring in the injection i'd reckon time would be better spent marrying up a multi-point manifold
 
these engines the 3.9 and 4.0 litre never and i mean never came out with a carby. it is a 2 barel trrotle body, with 2 injectors, it dont have a float a mixture screw , and so i would call it fuel injected or center point injection. its all controled by the ecu. they are a waster of time, u can use a redline 4 barle manifold, with adaptor plate to suide the head, port spacing is the same, and then use an xe electronic dizy with the gear turned up the other way ive heard.
 
The OHC would be a tight fit in a Corty. I have stuck a crossflow in a 69 Transit, and I had to do some cut-and-weld to fit it, as it is wider than the pre crossflow engine.
 
AUCTALLY, Ford did produce and sell a 3.3 Carb'd Version of the EA Falcon! I've got the factory Workshop manual & it does list such a thing!!
I've never seen one in the flesh & according to the production dates they only made them for two months so I doubt many exist (If any still exist today). I know what y'all are taking about though soooo many people confuse the CPI with a carb. I've even had stand up arguements with a custy over it.
