crazy but might work....

I was surfing ebay and thoguht of something.....will a tempo dizzy fit a 200? just wondering since a drop in eec4 dizzy could be had then...say for a xflow efi swap...or any other efi setup.

oh and I forgot....all eec4 caps are the same base right? and also you would hae to press on a different hall effect ring...like one off a 300 or 3.8 or some other six

Interesting idea...not sure if it would work or not.

Perhaps DG8TIM will help us. I'm looking at fitting 5.45" pistons to a 200 by using a 740 thou spacer plate, at the cost of 27 pounds of extra weight. This may make a 200 six a defacto 2.3 HSC six, with a good rod ratio and still light an compact.

The 250 could run 6.00" 2.5 HSC rods.

Does anyone know:-

1. the deck height of the 2.3 and 2.5 four cylinder engines?

2. and if the timing chain fits the six?

3. Is the 2.3 and 2.5 cam spaced out at ~4" from the crank like the 200 or ~4.375" like the 250?

4. What is the length of the pushrods on the Four cylinder 2.3/2.5 engines?

5. How big is the shaft diameter of the dissy. Same as the 200/250 at around 525 to 530 thou?

Four cylinder bits are built much tougher than six cylinder bits to cope with the shakes of the big fours, and the timing gears, pushrods and distributor may be the perfect swap for a wild six.

According to my Ford book of trivia....

Deck height of the 2.3 HSC is 8.700". Rod length is 5.45" with a 2.1236" big end and a .912" pin. Piston CD is 1.500".

Deck height for the 2.5 HSC is 9.400". rod length is 5.990" with the same big and little end. Piston CD is 1.579".

With 2.5 HSC rods and stock pistons, the deck on a 250 comes out to about .020", give or take a little, but gives you a better rod ratio and easier to zero deck for more quench. Would be a good base for a performance 250 buildup.

Beautifull, Jack

Still HSC related, I've started to look at these four cylinder 2.3/2.5's, and indeed the US 144-170 and 200's in a different, more favorable light since I first got a look at one 10 months ago. I'm just removing the pistons from the old 7.808" deck 200 Aussie Falcon engine a friend gave me.

I am interested in posting some fabrication diagrams for a spacer plate.

For these spacers to work, I need to know the ring land space, from the top of the 2.3 and 2.5 HSC pistons to the top of the ring. If its around the 0.275" mark, then it will be a good swap. The stock US-style 200 piston I have has about 0.275" from the top of the piston to the raised ring on down stroke. Are your US 200 pistons similar? The idea is to avoid having the top of the ring touch the top of the original machined face on its way back down.

Sorry, I must have missed this post. Here are some basic specs of the 2.3 & 2.5. It's the middle of the night & I've been studying for my Cisco Certified Network Assoicate exam way too much. I've got too many networking concepts floating around my head at the moment. I'll post your pondering over in tempo land and see if I can get any hits. I'll also check my factory service manuals to see what they say about rebuilding an HSC and see if they give anything useful.

As for the dizzy, I threw away a working 2.3 distrubitor awhile back. I would have gladly donated the whole thing to another inline ford freak for testing.

Measurement 2.3L HSO*** 2.5L HSC
in inches 2.3L HSC (Taurus*)
Bore 3.680 3.680
Stroke 3.300 3.583
Bore Spacing 4.080 <4.080
Main Journal Diameter 2.24985 2.24985
Rod Journal Diameter 2.1236 2.1236
Con.Rod Length (mean) 5.4570 5.990
Deck Height** 8.700 9.400
Pin to Top of Piston 1.520 1.579

*2.5L Taurus engine is 2.3L with a longer stroke
**Crankshaft centerline to top of Deck
*** 2.3 HSO is a 2.3 HSC with a more aggressive cam and more open head

Also, here's a link to the thread I posted over in Tempo land: http://www.tempotopaz.com/prod/index.ph ... 635#110635

Thanks Tim, good on you.

You have been reading the same hym book as Jack!

I always thought the bore spacings of a six was 4.05, but hey, my calipers may have been out a little!

With the US 200 sharing the same bore spacing as the 2.3, that's what brought me to the site. I'm happy to give back alittle for all the good information you guy's have given me.

That's okay. Still thinking of cutting up my spare alloy head for Floridaphatman. We'd like to see you shove a truncated alloy head and a 390 4-bbl on it.

6 = 4 , har har har.

Ve just vant all der HSC Konrods, pistons, timing gears (for our similar deck height Aussie and Argie 188/221's), pushrods and rockers you have, ja?

A friend had an 88 Tempo with all of those parts still intact. The tranny blew and it's sitting out behind his parents house.

Good. Your on my Christmas card list Tim.

Good. Your on my Christmas card list Tim.

If your nice to me....I can probably score you a 2.3 HSC distrubitor complete with ignition module, everything on the inside with a cap and rotor. That way you can look at it in real 3D and maybe tinker with it.

I'll let it go for the cost of shipping. (Assuming I can get it which should be no problem if the guy still has it)
