if the EST works fine, keep it. because it works fine. 
the leaded dissy also works fine, if you want to use it just join the 2 wires to the coil as it is now.
 
the engines aren't very different, other than rear main seal, maybe flywheel bolt size and various vacuum hose layout.. 

If the est is working then leave it.  If it's not then you could use the xe magnetic dizzy.  Just make sure it's in good condition and keep the revs sensible. 
Dont throw the est dizzy away - you will need it when you do the built motor.

Here you go, easy way to deal with it, Tried and tested:


You're welcome =P

 

Bring it down to NSW and Ill be in charge of marketing sales and beer.

I think you're under-estimating the potential of your setup Sly.
 
It's not like you're strapping a fart-can to a Hyundai. It's a dedicated, well-flowing system that has no sharp bends, rapid change in size or any shearing to the flow of the gas.
 
The twin systems that you might not like are the separate L & R ones with 1-2-3 and 4-5-6 going to each. They do sound terrible. However yours with the x-pipe effectively joins the two "banks" so the sound will be 6 firing pulses from each pipe, not 3 as with the other setup.
 
Another factor is the camshaft and breathing potential of the engine. If you over-exhaust a stock engine, you get that horrible ear-piercing bark like you used to hear from Geminis. Yours however is not stock. The pipes will be accommodated easily by the flow potential of the cam and engine.
 
Just remember too, one of the most glorious-sounding inline sixes in history, the Jag 6, is a long-stroke engine... with twin pipes!

Ef and early El are the same, late El.used a Au style head and crank, without the longer con rods (if you see an El engine with the prefix wr2axxx cat into it it's an Au style head with 1.8:1 ratio rockers compared to the earlier 2:1 ratio) and the camshafts don't interchange between the two ratios, Ef or El cam be set up for a distributor or coil packs (ea- can also be setup for coil packs but it requires a Ef/El timing cover, also to change from v belts to sepentine belt requires Ef/El timing cover and balancer *note v belts cannot be used with a Ef/El timing cover with stock brackets) pre Au: ea's have the strongest rods, ef's have the best crank (12 counterweights compared to 8 on all other e series) Ef/El blocks are better as they have oil restrictors in the top of the block to prevent to much oil in the head at high rpm (makes for more stable valve train above 4000rpm) ea cam is the biggest for made for a 4.0l (except xg xr6 but good luck finding one) and cannot be used on a Au without custom rockers, xr6 head use standard intake valves with a larger exhaust valve, they were also a different casting from a standard head with similar intake Ports but a much better exhaust port (the best xr6 heads to get have the casting no 93dt and 94Dt, the best of the non xr6 heads have the casting 94da). Au egas engines use better crank and rods than a standard petrol engine (also slightly higher comp, and an Ef xr6 head on an Au egas short nets 10:1 comp) Au engines can take a BA turbo crank and rods without machine work, Au rods are longer than e series with a hypertectic pistons (same advantage as using 3.3 rods in a 4.1 or 302 rods in a 351) a really nice Combo (what some of you will remember I had in my xh) is Au egas short motor, Ef xr6 head, ea cam, El intake with a set of extractors and a tune made 178 rwkw for less than $600

Keep the lpg and pull the petrol out My au gets about 600ks a tank on the hwy . Cost about $50 to fill the tank ..
 
If you put some more timing in it and it will go well also .
 
Only problem is in country towns it's hard to get lpg ..
 
It's kinda a unfinished project , I just put the 225 there because it fits better ..

There are 1 tonne load rated wheels from the utes if you are after something H/duty

I wear MOPAR shirts though LOL

The same happens with Hemi 6 and oil pump drives

Late XC 351 with a Borg Warner had 28 spline
XD and XE 351 had 28 spline
EB series I 5.0L had 28 spline
EB II onwards had 28 spline in everything
AU onwards has a wider track and longer axles
