I’ve read some other threads and talked to some experienced AMC guys, but I thought I’d put this thread out there as I prepare to install my 360 into the 1973 AMC Hornet Sportabout X I picked up the other day. Fitment-wise, it has Patriot Clippster shorty headers and tall aluminum valve covers going into a PB, PS, V8 car.

Here’s some anecdotal info I have so far:

-Start it canted a little to the passenger side and swing it straight as you lower it.
-Loosen the transmission crossmember bolts most of the way to lower the rear of the transmission
-Jack up the front of the transmission and tilt engine rearward then slowly advance them together until dowel pins slide in.
-Put engine mount pads in crossmember first with nuts just started and bolt to engine once it’s in place using a punch or screwdriver to center mounts to engine threaded holes.
-Use a mini starter.
-Get drunk and do it at 2AM.

I fully understand the last one. Kidding... Any value to the others?

I don't think the Clippster headers will fit the small body cars without some modification.

If you need a tool and don't buy it...
you'll eventually pay for it...
and not have it.

Don't know about your location, tools, time, and so forth but the best method we have found is remove out the bottom and install from the bottom. Just like the factory. That my not be practical in your case but I thought I would throw that out there.

Yeah, that’s what I’ve heard. Hopefully nothing a couple of gentle dents and a light application of grinder can’t manage. Engine installs suck when you spend half a day or more on ancillary tasks. Sometimes I miss my FSJs...

If I can figure out a cradle/fixture for the engine, I may give that a shot. If anything it’ll be a good experience doing something different.

We got creative with a "fixture"... LOL

We did this a while back on my friends Hornet and the engine is a VERY tight fit in the Hornet/Gremlin bodies.  It is so tight that on '70 models, you could not remove replace the heater control valve. The TSM had instructions on how to hacksaw part of it off and reuse it with either pop rivets or sheet metal screws (can't remember exactly).

We did the motormount trick described by Red20 and that helped a lot.  Best option is to install the engine first and then get the car high enough to get the trans in from underneath. Bolt it up to the engine and then raise the back end up to install the crossmember.

Of course installing everything from the bottom is the factory method (Chrysler did the same thing) but that's a lot of effort unless you are restoring the car from the ground up.

Just IMO.

I really appreciate all of the thoughts here. If anything, it encourages me. I’ve had easy breezy installs and nightmare installs. And I always went into them thinking they would be opposite of what they actual ended up being.

I will be getting rid of the lovely Eaton PS pump for a Saginaw unit. I’m tired of it spraying my engine bay at high RPMs.
