Wednesday it was time to dig the 45 out of the corner and start setting the motor in it. It's so nice to work with all brand new parts!

It took a day to assemble and find the right spot in the frame for this jewel. There's a bit of head scratching to make sure it clears the fire wall, front drive shaft and steering shaft. We unfortunately had to tilt the motor a little to make sure we had enough room for the front drive shaft, but it's only a half inch lower on the passenger side, the aluminum oil pans on the LS are much larger than the old small blocks. We can live with this.
On a 40 the tcase is very close to the frame, but on the much wider 55 frame this is non issue and the rear drive shaft is in perfect alignment.

Next was the trans mount. We looked at what AA had supplied for a cross member, and didn't really like it. 1" ×2" 1/8 wall with no inserts in the mounting holes, too easy to crush it by over tightening the mount bolts. It just looked too flimsy for 300+hp, plus it was too short to span the 55 frame.
Also, with the supplied center trans mount the cross member would be about 4 inches below the trans. This isn't a wheeling truck and clearance isn't an issue, but we didn't like it hanging that low.
So Wally fabbed up a new cross member that is much tighter and stronger. Complete with cut outs for the tcase front output bolts, capped ends and inserts for the mounting bolts.

We'll use the factory rubber pucks on the frame mounts, just like, well, factory.
