Can this be done?, are the main seals to different ?
Ive heard they fit a 87da, is this true?
Cheers.

All EA-EL1 cranks are interchangeable
EA = 6 Counter weights
EB2-ED = 8 Counter weights
EF = 12 Counter weights
EL1 = 8 Counter Weights
EA = 6 Counter weights
EB2-ED = 8 Counter weights
EF = 12 Counter weights
EL1 = 8 Counter Weights

My pre x-flo 2v has an EF 12cw crank. Apparently cost $600 to get the machining done tho. Can post photos if anyones interested.
ef crank will fit the older blocks when you machine the rear main of the block to suit the bigger seal of the ef. you could machine the crank but this puts the seal closer to the flywheel bolts. then you get XF problems of the rear main leaking. machining costs aprox $70 from any shop worth their dollar. cheers
yeh i still wanna go the ef crank and rods with the low comp piston, just so i can wind the boost up......
Problem im having now is getting a wrecker to take the crank and rods out of their EF motors now as my ford wrecker here went back on his word, so anyone here got one or know of somewhere??

im yet to ring around addo, but i have a 86da block so from what i hear its a bolt in thing with only the rear main seal needing machining, shouldnt be a really expensive exercise id imagine but i could be wrong too... all depends on what you do yourself like always??

Posted a couple of pics of the machined EF crank plus a photo of a STD crank out of a 82DA??? The motor that the EF crank is fitted to is a 72DA. Was fitted with flat tops, EF crank, Ported 2v head can be seen in the background, big valves, .590 lift solid cam. Was told by the previous owner that it used to run low 8's down the 1/8th mile apparently it ran one 7.80 but he could never back it up.etc.
Looks simple enough to machine. Also doesn't look as though it was leaking.

Hey guys i just wondering what crank would be best to install into the block????
and how far the rear seal on the crank got to be machined?

Hi Kiwi
Any photos or close ups of the machined block without the crank?

Rear main of block is as std. The rear snout of the crank has been machined down to the same size as the original. Which from memory is the same size as windsor and clevo 2 peice seals. The Flywheel bolt holes also need to be drilled out to EB1 and earlier specs. EB2 onwards use a smaller flywheel/flexplate bolt...
XRglen: why would the proximity of the flywheel bolts to the rearmain seal cause the seal to leak???
XFs had a poor quality single peice rear seal to start with. Same as EF rear seals... But worse!
Just use the Victor Reinez(?) or Felpro rubber replacement 2 peice rubber rear main instead of the original rope type seal.

when the bolts are close to the outer edge of the seal surface, they cause distortion when they are torqued up. this is why ford went to a smaller flywheel bolt on 86 on motors. i just rebuilt a 250 and used a el crank and machined the block out to take the bigger seal rather than machine the crank down as this will cause leakage due to distortion. cheers
Dredging up an old topic, but are there any good photos available of the el12cw-into-XF block?

how does the motor feel with the EL crank in it? what differences have you noticed in the rev range?
there is no differance in the performance but i was sick of breaking flywheel bolts and loosing balancers every time i hit 6000+ rpm.
i now run a romac balancer aswell and the motor has a 244@50" solid cam with 12:1 comp. just dynod at 365hp@5900rpm with a 650cfm demon on a cain inlet and custom extractors. the specs sound over the top but it is real nice to drive and pulls hard from 2500rpm. in runs on 98 octane with 10% tolluen and nulon octane booster, works out at $1.78 per litre..cheers

how about the rev range, does it have the same harmonics and "feel" as a crossflow?

Just for my sake, could someone quickly go over the reason for switching to an EL 12 counterweight crank? Is it better at high rpm/ more or durable? Does it increase of decrease the stroke?
