350 Chevrolet Installation

Way back in October '04 I figured it'd be pretty easy to have the engine swapped out over the course of a winter, but it just wasn't to be.  I spent a good deal of January chasing small parts and put myself out of commission for February and March '05 by herniating a disk in my back (probably a result of playing with the D20).  Here is the 350 ready to be installed (early Feb '05.) using the same "roll it over a series of pipes" method employed to remove the Cerlist. The engine rests on its crossmember which is installed to prevent damage to the oil pan, and the rear of the engine rests on the flywheel
Once the Chevy 350 is rolled underneath the van, the hoist can be positioned and the engine raised.  Once the engine is raised into proper position, the crossmember bolts are loosened.  This allows for enough slop in the mounts to allow for lateral positioning of the rear of the engine once the transmission and transfer case are bolted in place.
After the transmission mounts are secure, the crossmember is tightened up and the hoist can be removed.  Click here for a  View from below.  The bolt-on was to be a temporary solution to get the van up and running quickly, and would have been welded in later on, but as nicely as it worked to hold the engine,  I would later find out it wasn't going to work at all.
I busied myself with other things for some time and hence didn't realize a big error was made untill after I reinstalled the front axle.  The engine crossmember hung down too far and  was only one inch from the differential housing.  The fuel pump is also a little close for comfort, but that can be fixed by using an electric pump near the tank.
Time to start over!
I spent quite a bit of time sketching out different methods of supporting the engine.  Nothing I designed was to my liking and finding a compatible urethane or rubber mount proved impossible.  So I decided to go with this kit from Novak Conversions.  The kit (Novak# MM29 $121.00) has been redesigned to allow a Chevrolet 350 to drop down between a Forward Control Jeep's frame rails without removing the exhaust manifold and is adjustable for height.  The kit comes as shown in the thumbnail.  The image on the Novak's webpage for part #MM29 has not yet been updated to show this change.
When bolted to the engine, the Novak mounts span 28.5".  To fit between the frame rails with the added thickness of four pieces of plate I had to trim off a half inch or so on each end.  The picture to the right is an early mockup with the new mounts.  The cardboard will be cut to make a template for a piece of plate that is necessary to cover a couple of holes in the frame.
Now its a simple matter of tacking the plate to the frame, the frame bracket to the plate, and double check positioning with the mockup engine for clearance issues.
Completed installation with axle under load.  Note clearance for the harmonic balancer is not quite as great as I'd like and the front drive shaft hits the starter at rest.  A new set of properly arched springs and a little tweaking of the engine position and I should be good to go.  Nice thing about the Novak engine mounts is there is quite a bit of vertical movement in them.  A close up of the completed mounts can be seen here.
