Anything to know when using a motorplate? Water pump? Balancer? Alternator? Pulleys? Anything else?

that is something for me as well .
I know you need limiters , fore & aft movement .
Andy does a plate and crank pulley spacer , Can you run a stock style alternator ? Low mount ? DMI show a low mount kit

I think Magnumforce do a high , left side , alternator mount .

sorry for the hijack

You just need to got to AR Engineering and see all the cool stuff for motor plate installation. I just used the crank pulley spacer and the low mount alternator kit for the Denso alternator.

I have the water pump housing machined the thickness of the plate or elephant ears so all the pulleys align properly up scope
I have not had to add a fore and aft travel limiter either using a stock tranny mount shruggy
That being said, maybe I should have work confused shruggy

I never had the horizontal limiters.It seems fine with the thick motorplate and just the midplate.The motorplate also spaces my waterpump out giving me good clearance for the gear drive.I've seen some sanitary limiters from the trans to the trans crossmember.
If you are fabbing the engine plate & midplate at the same time,,,,,,set your engine back as far as you can!!

The limiters help a lot specially on a race car..
I ran just the motor plate and a mid plate and
it would bang the engine off the trans bushing
till it broke and it was pushing in on the trans
so I added the limiters.. was a big help and I
never broke another trans mount

Definitely need a fore-aft limiter of some sort. You can always leave one factory motor mount on it to act as a limiter. That's what I did on my B body...the passenger's side factory motor mount is easy to get to and not in the way of headers, so I left it there to serve as a limiter.
A midplate isn't a necessity, but they aren't a bad idea if you have room for one. I don't run one on my cuda.

Low mount alternator kit is the way to go. I use the DMI kit, but AndyF has some nice ones too.

Make sure your frame brackets are located BEHIND the motorplate.

I set my water pump housing up on the head surfacer and cut it down to offset some of the distance the motorplate spaced it out. Not necessary if you run an electric pump, but it helps w/ packaging if you run a big alternator and fan.

good advice!!!

I run the fore-aft limiter from the frame to the motor mount tabs on the block. there may be a better spot to mount it on the block or trans, but the options are limited with so little room.

Not sure which plate OP will be using, but another benefit to having the frame brackets behind the plate is that switching to a thicker plate won't push the motor back.

I have both a front plate & a mid plate on my Challenger. I made some for/aft mounts to the trans cross member since there is do little room left in the engine bay with the Hemi & big tube headers.

Studs or bolts for waterpump / plate ?
Looks like studs would be easier for locating gaskets etc .
Does ARP do a kit ?
thanks

Tends to flop around a little if you don't bolt it down with all three holes in the bracket....like this.I also flattened out the other small bracket and use that as a backing plate behind the aluminum motor plate.
