Hey all Saw the thread of the holden V6 and thought it wouuld be good to setup one for the Ford 4L Straight 6
Could I have a list of the definitly needed mods to make a Ford 4L el/au last a season in a stockcar please.
You know - those things you'd do first if you started with fresh low km motor out of road car. Any tips or hints or secrets in building one up
Thanks

I gave mine a good wash out,honed bores and new rings and bearings for a start just because i wasnt sure of kms.

ea(so ive been told) manifold,and xf carby/holley with adaptor xf 4.1 2 wire dizzy,others can be used but the 2 wire is easiest to wire up.. upgrade the cam,cam gear ive been told to get the timing around the 40 mark... i think my last one was set at 38
ive heard of guys getting a motor from a wrecker and it lasting 2 seasons without problems..

yea iv also herd the ea intake manifold is the way to go. Also the XF/XE distributor holley carby cam cam gear rebuild the engine etc

On my AU2 motor - ~ XF inlet manifold, 350 holley, carb adaptor from HRP ~ EA Alternator, ps pump, and crank pulley (had to machine the rear of the pulley by about 10-15mm from memory), and custom mount alternator (EA brackets for alt dont line up on AU2 motors, any engine prior to AU2 is a straight bolt on from what ive been told) ~ XF 2 wire dizzy and coil to suit
Modifications are purely an option, stock 4.0L engines go very well as they are.

Is the EA a good base to start from?
What bits need to be tweeked?
AU heads?
Cam?
etc.

The EA is an ok base, but for the price of a AU why bother?

I have an EA complete and can get a AU tickford head for $200.
An AU will cost $500-1000 without starter and pumps etc.
Will strip either down and we are running an EL in it at the moment.
Will be running a Rees engine girdle, are the same for EL/AU?
They are for EA/EL.

Should be the same yes, virtually no difference in block. Tickford head is a good option, just check its straight.

are you sure it was a xy manifold clive because the xf inlet manifold flanges have the bolts vertical as the ea manifolds have the bolts off at angles.
and its the centre point injection manifold off the ea falcon not the multi point.
just use a xf falcon weber carb, already jetted correctly and way more reliable.

quick question
Can a EL run a mechanical distributor from a XF/XE with the injectored intake manifold from the EL? or is there not enuff room?
Thanks

Well as ELs did run a dizzy there should be no problem.

standard Au tickford low Ks straight from wreckers put out 130kw at the wheels running a xf dizzy have a supposedly worked 1 siting in the shed that has had 8 grand spent on it that is putting out 138 at the crank so figure that 1 out

was the 8 grand worth it? maybe, for the serious racer... probably not for the budget minded...

138kw at the crank is a big drop to the wheels for 8grand.
You lose what, about 15% from crank to the wheels?
138kw = hp? (200-210?)

There is also average flow in the carb manifold compared to the multi-plane manifold used on the efi. What you will notice, particuly with a well profiled camshaft and correct cam timing, is that although these engines may seem to drop in HP, usable torque across the range is greatly increased. Although that is assuming the engine builder hasnt just butchered the whole engine.

So It would be best to get rid of the AU EFI intake manifold and run soemthing else? what intake manifolds best to run with a carb on a EL/AU tickford engine?

Better to use the AU injection manifold,when combined with correct cam package gives a much wider rev and power range.

If you want it to rev and produce top end power, the short EA single piont efi manifold will work best. If you want torque, the EF-AU dual plane manifold will work best, with the short plane closed. Short inlet runners = fast revving. Long inlet runers = more torque. Most do run the EA manifold, but there does seem to be a few more poping up using the EL manifold. Remember these engines was designed by Ford to produce good torque and last a long time, so they are never going to rev to kindom come like some other engines. The guys getting the most out of them are the guys building the engine with a torque curve to suit their gearbox and final drive ratios.

Hey guys got au series 1 with auto trans I just finished doing a CRB conversion to it and need to work something for the automatic transmission like a computer or something I don't know much about it .
