Can't state anything about spool mount but my A-body has had two "motor plates" the first being the old elephant ears style and now AndyF's motor plate.

A motorplate is very convenient. It's a great place to mount things like the coil, vacuum pump, breather tank, alternator, etc. Much easier to unbolt than typical motor mounts...makes engine removal and installation much easier. Plus it frees up a bunch of room under the car when you get rid of the standard mounts and brackets on the K frame. MUCH better for header clearance...especially on a hemi. It's probably stronger too now that you've tied it all in to the frame rails...acts as a stiffener b/t the front rails.

Just remember that a plate resists rotation ("roll") very well - it's in shear. But weak w/r/t angularity ("yaw", lateral motion, like moving the tailshaft left-right).

What are the pros/cons of using a Plate vs Schumacher Spool Type Mounts in a 2nd Gen Hemi application in a '69 B-Body?
My current parts list: Gerst Suspension TTi 2 1/4 Headers Indy Maxx block and SR Heads
Thanks!!! I assume since you have the Maxx block that you're going to be making some power. Once you get up past 700 or 800 hp the stock type mounts really have a tough time holding the engine in place. You can use the stock mounts and add a torque strap but typically the serious guys just move to a plate. I wouldn't use a plate on a daily driver type of car, but I would use a plate once you start making some serious power.

I use both a motor plate and a mid plate on my Rampage but its a tube chassis car.. the plates add to the rigidity to the chassis.. I also have plates on the race car.. the Rampage is a street rod.. it drives very nice on the road

Even with or without a mid plate in addition to your front plate. Don't forget to add the engine limiters for front to rear movement also.

I'm going with the AR Engineering plate.

You'll still need some sort of fore/aft limiter. I use a setup similar to this...

It all depends on the application, Stick car needs a fore-aft for sure to keep the clutch linkage in check. I use Andy's plate and a fore-aft limiter with rod ends attached to the K-member back to the side bolt on the blow shield and it keeps my clutch adjustment constant. I had a conversation with Herb McCandless about this and he told me the the block will have less stress if you use a motor plate something about the block being pulled on the skirt near the main centerline.

I run solid plate on front and a solid tranny mount on mine. Street driven with no issues. I got tired of ripping stock rubbers. Would be worse on tearing them up now with the blower on it. Have you ever hooked it up at the track? Slipping and sliding on the street won't stress much.

B/c the plate or ears WILL flex fore/aft. How much depends on your trans mount and the power you're making. I use a poly mount. Stiffer than rubber, but still allows some movement. Also, like I said above...slipping and sliding on the street doesn't stress things nearly as much as actually getting traction at the track.
