Don't mean to be profan, profug,prodfane, oh, you know, a dirty bu**er, but is the AU/BA corod 156 mm (6.15") long or 152 mm (6.00") long? How much bigger were the crank pins than the X and E series Falcons?

:idea: Just realised that the Yank 2.5HSC four-cyl Topaz/Tempo rod is the same as the 3.3/4.1 engine for wrist pins and crank pins. Could be a good swap if you are putting horrible old 221/200/188 pistons or even Chevy 305 forged pistons in a 250 with almost no modifications.

Another useless piece of info. :lol: :stick:
 
from what I know and have measured:-
Ea-el all 5.88 but a better rod than the earlier ones
Au is longer than EA etc, my guess is 152mm, I dont think any longer could be used in EA style block height, which is 9.22, lower than Crossflow.
Does this help?

Yeh, thanx A7M. Ever since Gregories, Ellerys and Haynes stopped with the rod centre to centre spacings in the early 80's, my life has been hell. Getting true information is a PITA. And finding FoMoCo books on cammers is harder than getting info out of a secrete society :cry:

To recap:- EA-EB-ED-EF-EL-XG-XH

The wrist pin to top of the out side of the piston is about 1.385 (or 35 mm)
The con-rod centres sound bang on for EA-pre AU, at 5.88" (or 149 mm)
The stroke was 3.91" (99.314mm, no change since the first US 250 in 69)
Deck height 9.22" (234 mm)


Back to AU-BA SIXES. Do you or Backlash have access to the blueprint figures Ford used to put out?

How much bigger were the [AU-BA] crank pins than the X and E series Falcons?

is the only other question.




 
Gidday Xecute ,you all wrapped up in ya winter woollys....
The intech 4.0 au uses the same bigend bearing as the crossflow and the
ea/ eb but the main bearing are different ,from what ive heard they run a
bearing cradle for the mains .Shaft size is 67.481/67.505 (2.656/2.6577)
20.90 wide on 1-4,6-7..number 5 has an upper and lower shell .Lower is
20.90 wide upper is 27.38 wide. bore is 92.26mm stroke is 99.300
looks like these mains came out in el falcons 1998 on block numbers
VR-2A-6010-AA ..
PIN SIZE FOR AU 8/1998--02 is.......... 23.180.
looks like the weathers packing up down your way ,have a good weekend.
cheers dave
 
Brother, its white down here. SNOW RETURNS, YEEEEEHARRRR!!!!

Hung with the grit and CMA boys tonite, and they've not seen snow this thick at sea level in ages. About 100 mm or more in places. My friends in Halfway Bush are loveing it, its ultra thick there. Planes have been stranded, and ice is everywhere. Workmates are stuck in CH-CH, poor beggars!

Thanks for the info Dave, really appricate it.

Got dibbs on a Cortina Four station wagon, with evil plans for my high winding 228...but I'm trying to pare down the front end weight. I may bail on my 221 crank, and go for an alloy head early lo-deck 200 now. 158 kg verses 218 kg is a big mass to gain.

My Falcon is getting too big for the misses...(both still the same size, but Mornington is heaps narrower than Halfway Bush, and its a PITA to give way to ricers all day)
 
A low deck 200 Alloy head. I thought the low decks were only pre seventies and not crossflow.
Are you plaining some "amazing mods" or mix and match. Arent you worried about the rod ratio with the lower deck. I agree its a big weight saving.
Whats your thinking?
 
The Explorer SOHC Cologne V6 is over 245 kg, (540 lb) ready to run
The fact that the the iron head cross flow 4.1 is 238 kgs (525 lbs) ready to run
The EFI 4.1 is around 237 kg (522 lbs) ready to run.
The alloy head carby 4.1 Alloy head is 215 kg (473 lb)ready to run
The carby 302W with alloy intake is about 213 kg (470 lb)
The Essex V6 from the GB Capri is 432 lb
A early tall deck 3.8 Holden V6 is around 196kg (431 lb) ready to run as a manual
The Cologne 2.8 FI engine, 164 kg (364 lb)
The Cologne 2.3 V6 , from my old Cortina, is 158 kg (348 lbs)
The US 3.8 Ford Even-fire is about 141 kg (310 lb or so)
The Pinto 2.3 is 139 kg (306 lb)
The Cortina four is 131 kg (289 lbs ) ready to run.

The 200 low deck with alloy head may be around 145 kg (320 lb).

Bearing in mind the cost of redoing the Cologne V6 or getting stuck with an orphan US 3.8 V6, or a "foreign" (non-Ford!) Holden 3.8, I'll stick with a 200.

Two and a third full bags of cement off the front end. The rod ratio will be covered off by my spacer plate. That gives me an extra 208 thou of plate gives me a 8.038" deck register, and then I can use my Project 228 pistons. (1.475" tall). With some 5.00" ohc Cortina rods with good bolts, a 78 thou crank pin grind down to get a good fillet radius, then I'll have a big weight saving and a 1.6:1 rod ratio.

Then I may consider bailing on the welded 221 crank I have in my 250 engine block in the garage. 90 kgs saved. :hmmm:
 
Sounds good. But from one of your other posts you seem to have the know how to make it handle even with the bigger heavier six in it. I still like the fact that mines got a 4.1 not a 3.3 like the Toranas and Commodores. Each to his own, a lot more fun to drive if it handles well I guess.

With the battery in the boot and an alloy head it would make a fair difference. And I seem to remmember that it is also possible to save a bit with a different starter motor and some other minor changes.
Probably not enough for what your after
 
I know what I want, but I guess I'm not sure exactly how I'm gonna go about getting what I want either!

I've had a few bad ideas, like loosing cubes to gain rev range on my 250 engine, and I guess it may be better to stick with what I have. Maybee a fibre-glass flip front and the rear battery and the like is the better option.

Loosing 50 cubes to save 90 kilos may be a similar stupidy. If I combined the hood and guards and grille as a one-pice fiber glass unit, I could use the rubbing strips as a split line, and save 100 kgs. A battery must be 20 kgs or so, so now I'm back to where I was in January when I discussed this with Discokin6 and others on the post on my old V6 Cortina. He told me go for a 4.1 Turbo. or an Explorer 4.0 V6

As addo knows, I have an old M45R gearbox form a 360 GLT Volvo with 3.64:1 axle gears. It's like a Volkswagen box or Alfa GTV/Alfetta gearbox. They are a rear mounted DeDion gearbox, and my mate Paul W. has the spare transtube and tubeing axle that makes the set up a fairly easy bolt-in. I could build a wild Alfa Romeo Guilietta-style diff set -up to knock off some more weight from the front to the end. Only hassle is the wide ratios...3.71:1 first. 5th is good, about 0.79:1. Parts are cheap as down here!
