Coming along nicely! Don’t forget to use thread sealer on the head bolts that go into the water jackets. Get some AU spec rocker cover gaskets, they are reusable and seal perfectly, I don’t like the cork ones at all. Same with the manifold ends, just use sealer and use a bit around the water ports as well, I’m sure you are all over this though. Sent from my iPhone using Tapatalk

I’d do AU bottom end. It’s got a better combustion shape in the piston crown, longer rods which give you better angle in the bore and more torque down low and cross bolting of the alloy sump to the mains caps. What’s not to like?? Dave is spot on with the head. See if you can find a non vct Xr6 au motor. Better cam, valve springs and exhaust valves are 2mm bigger.

You dont waht to do that without boost, that combo will drop comp down to about 8:1

i had to chainsaw it off because off stuck bolts,new one coming monday says suits hawaii 5.0L

What’s wrong with the original timing cover?

call this song the DURATION

Maybe you got a flat tappet camshaft?

An EF core, should have the better balanced 12 counterweight crankshaft. The late EL/AU hybrid cores, have lighter valvetrain assemblies and better flowing cylinder heads. Maybe an EF bottom end, with a Hybrid cylinder head assembly?

dizzy just pulls out and swaps for the crank angle sensor thing for coil packs.. depends what you are doing with it.. if you read Thoms ohc thread you'd be getting an AU bottom end with an EF XR6 head and running a bbm .. that carby look think will probably be on it's limit pretty much standard? but then again, look at Campo's barra NA conversion into XF and it's making decent power NA.. or look at blackxt's current thread with turbo Lpg 4.0 and you'll be thinking turbo... then think turbo and look at the turbo crossflow times .. that's what you have now, then think you want to keep your exhaust so follow slydogs blower setup .. hmm. then remember the sparkydave slogan.. keep it stock date code correct, genuine parts, don't drive it for 10yrs to keep the kms down, don't die before you get to drive it because whoever inherits it will take it to scrap because old car.. that got a bit out of hand..haha

also seen reference to people using them on escort etc.. probably wouldn't be that hard to stick even a couple of them in place of a 4 barrel carb..(you know you want to)

knew i'd seen that "carby type throttle body" used elsewhere..(post 13) i may read it for the gemini, but there is an EFi manifold that bolts on.. would be interesting running efi under the stock air cleaner too though http://www.performanceforums.com/forums/showthread.php?67260127-Blow-through-Weber-carb
