WEIRD 84 CROSSY REBUILD XE XF ?

[CHESTNUTXE 7,299]

I just got home from picking up this cortina engine but i reckon its a bit of a jigsaw engine,lets sus it out.from what i can first see its a 84da block with c2 head,but has xe dizzy stlye,or could possibly be a leaded 84 xf engine,it also has 82da manifold,or this could be the year the first cast numbers were done ,and a very large or bigger than mine water pump pulley,it also has a jg23 engine code,mounts could be f100 ?? not sure but chime on in with what they are ,so lets put it on the stand and start to ripp it down.

Engine mount rubber looks like xr falcon... not sure about the bracket. ..

@Thom would probably know more as he would have had to mix n match for the xp

Your right on the engine mounts they are xr/xt, was this engine In an early falcon? Having those mounts and the early water pump make me think so as the clutch fan water pump will hit the radiator in an early bird, and the bigger pulley makes sense for a car with 3.5s (most early falcon sedans had 3.5s with xp Fairmont having 3.2s and utes having 4.11s) and no overdrive you want to slow the water pump down at cruise speeds to stop it from cavitating the water, you may find the water pump pulley is from a pre xflow (that's where I got mine from an xa pre xflow 250) to help keep it cool on the highway

By the black forest in the chambers i would say this thing had the holley treatment as manifold ports are blocked off too she is also a 020 and no lip on the bore

manifold throat looks ported(for adaptor plate?) 

looks like a good engine, may even have a decent cam in it? take the oil slinger off and see if it has adjustable keyway on the lower timing gear

pistons are the 29 cc variety

[deankxf 20,263]

cam spec might be in here, 

edit.. reading further? no idea

 

[CHESTNUTXE 7,299]

also chamber is c2 high swirl i have read somewhere,i just cleaned this one up a tad so we can look ,all looks pretty good,id say maybe 50/100,000km maybe ? maybe less,im gunna measure the cc of the c2 unless someone knows off the bat but im guessing 48cc

[deankxf 20,263]

head chamber looks different to i remember around the exhaust valve

[deankxf 20,263]

is that a crack between the valves?

 

[deankxf 20,263]

cracked?

 

 

[CHESTNUTXE 7,299]

nah i just checked on a dirty one,its the same its like a small ported line that goes from chamber to chamber ?

[Ando81 2,949]

I’ve been told it’s pretty common to see them crack through there as there isn’t much meat to hold it all together.

[CHESTNUTXE 7,299]

it aint cracked  all six are identical

[CHESTNUTXE 7,299]

i will check the main size tomorrow ,then see if the crank needs a linish/polish ol,m8 does it for $50,also buy some kero and degreaser,then start my cleaning process.

[ando76 4,354]

It is a crack.  Very common to have them crack there. It's not an issue tho and will work fine. 

If it is an unmachined c2 it should cc at 42cc, but could be less if it's had a hair cut.  No evidence of anyone laying the chamber walls back so I'd say it will be 42cc or less.
