I did not plan on using one. What exactly is the purpose of a motor plate? I am going to have a turbo hanging off the passenger side also.
Well there are several reasons;
1. Ease of install 2. Some blocks don't have motor mount provisions 3. The engine is now solidly mounted and won't twist. There for a little more power is put to the wheels. I believe it will help your 60ft. Hopefully someone can chime in and verify this..

I have seen alternators driven off of the pinion yoke on the rear end.........and with a pick up , room should not be an issue. I have seen this on more than a couple street rods and I really like the look under the hood. Just a thought. ![](/ubbthreads/images/graemlins/whistling.gif)

Worth loooking into, but I just don't like how those things look hanging off the front.
I looked into that awhile back...With a 9" Ford there are a few options, I suppose one could be adapted to a chrysler 9.25.
Look here
Problem is if you're not moving, you're not charging

So I am putting a FAST XFI system in my truck along with a set of W9 heads. So I can't use the stock alternator anymore because of the control of the PCM will be gone. I also can't use some of the alternator brackets out there because I don't have the fittings on the heads. I am losing the power steering and going to a manual rack, so I have room where the stock pump used to be. I am also going to a electric water pump. So is there a good bracket that uses the block or water pump bolts and no head bolts to mount? What alternator works with it, need about a 120 at least? How do you space out the pulley to work with the MSD crank trigger? Just go V belt?
A couple of ideas. Most of the computer controlled alternators can also be controlled by a standard 70+ MOPAR flat pack voltage regulator - your OE alternator may work fine if you can get get the brackets adapted to the heads. The other thought is can you use the crank sensing strategy on the original engine (flywheel pickup?). If you could it would save messing with custom spacing from the crank trigger.
As I'm sure you know, EFI likes a steady voltage and you probably have a good sized fuel pump and maybe a fan to run so you need a strong alternator with good idle output. OE would be good. A 120 amp Denso would be good or a 140 amp Powermaster/Delco. I wouldn't go with less alternator than those.

You don't need a new alternator nor a one-wire alternator. You can use the factory alternator if you can still mount it up. You are correct in that the PCM controls the regulation of the alternator, but it's not that complicated. You can install another external voltage regulator to your existing alternator. Your voltage regulation is an "A"-type in that the field is controlled on the ground side. The voltage regulator is simply controlling the output of the alternator by switching the field current on-off to a ground in the PCM. You have two small wires...right? A White and Dark Blue on pin#1, and a Dark Green on pin #2. The White and Dark Blue is battery power with key on. The Dark Green is the switched wire. Connect the White and Dark blue to Key-on battery source (fused). Attach an old school external voltage regulator (type A) to the Dark Green wire. The 71-up electronic 2-pin VR off any Mopar should work. It'll need to be securely grounded and it will need a voltage sense (battery voltage) wire so it can tell when to charge and when not to. An old Mopar performance book can give you the simple wiring diagram for the two wires on the VR. The VR is cheap and easy to find at any auto parts store. The triangle shaped plug is easy to find also. The earlier 70-down electro-mechanical VR's were B-type. They were switched on the power side. Actually either one will work if it's wired in correctly. Piece-o-cake. ![](/ubbthreads/images/graemlins/grin.gif)

So you mounted it to the cast alluminum fuel pump mounting holes on the original timing cover? Pbody
Career best 8.02 @ 169 at 3050# and 10" tires small block power.

Yes... I made a steel bracket that spans past both bolt holes, it drops the upper pivot to about 1 1/2" below the pump bolt holes... I'll see if I can get a pic tomorrow... I've had it on 3 engines for the last 12 years now... no problems at all

Would you be willing to make another one? I can pick up the timing cover pretty easily if you can.
I can build another... would be no problem ![](/ubbthreads/images/graemlins/wave.gif)

I am assuming that the lower hose won't work on the passenger side?

My lower hose is on the drivers side... using a electric pump it has the threaded hole on either side for the hose nipple ![](/ubbthreads/images/graemlins/wave.gif)
