Hey Paul

As you have now made several highway trips. have you found the setup using the 3 ribbed belt to be safe?

Hi Ben,
Yes, no issues at all with the 3PK940 belt and EF pulley. The engine's also been over 5K rpm a couple of times as well. The ridges are the same spacing and torsion holds it straight.

The ridges on the pullys have a different pitch from eb to el. if you actually sit the eb belt into the el pulley and have a look you can see that it doesnt sit right down in the groves. This will soon chew out the belt... Trust me i know. To do the conversion properly you need to change the pulley from the one off the 70amp mitsu and put it on the el alt, and with the alternator off remove the lower bracket off the block and with a hacksaw (so you cut it straight) cut 5mm off the front of the bracket where the alt mounts to, this allows the alternator to go back far enough to make the alt pulley and the harmonic balencer pulley line up. Grab the top bracket and grind about 3-4mm off the bottom section. Then grab a bolt that will fit through the bracket and alternater and weld another smaller bolt to the head of it... this way you can put the bolt in through the back and still have your tentioning nut on the front with a nut on it to lock it in and you can tighten it with out needing to hold the bolt head (which is impossible to get to). Then fit the lower bracket back to the block but when you fit the alt to the bracket put a 3\8 washer at the rear of the bracket between it and the alternator so it still tightens up ok. then fit top bracket, tension the belt, tighten it all up, plug in all power cables (which are the same just different locations but the wires reach) and away you go 100amps are now all yours!

Thanks for that optional way of fitting it Flash but as you can see a few posts above, it's all finished.
It sits perfectly straight, no welding, full adjustment, only the top bracket was ground and the lower rear bracket eased by about 1mm, no washer needed, full access to the top bolt and nut [both sides].
If you look at the pictures above, on a spare block, you will see all the points I mention quite clearly. It took about 15 mins and 1 tool to do [not including spanners].
I had the 3PK pulley on but took it off as it touched the housing a little, the EF pulley has been on for over 2000klms so far with no unusual sign of wear on the belt. The engine has been run up to 5200rpm without the belt showing any signs of wayward movement and the car regularly runs at freeway speed.
I regularly check the alignment and wear but so far all is fine. At least 12 Fordmods members checked it out at the Koala Park AFD and no-one noticed any mis alignment, in fact the main comment was how straight and smooth it ran with the EF pulley on it.
So after 15 mins of actual work 110 amps was mine and although different to how you did it i believe it was also properly done.
Cheers,
Paul

Ben,
Heres a few more pix, don't take as much off the top rear part of the bracket as I did.
The camera distorts the angles somewhat, but the belt lays straight enough along the bracket straight edge.
