55.2-59 Stupid Question about placing engine mounts

[Dan in Pasadena]

Hi guys. Sorry I didn’t see this thread til now. I was surprised to see a pic of my chassis and garage!

Funny I saw it today because I was JUST fiddling with the trans cover last night. We had to switch to the factory four speed trans cover instead of my stock three speed cover to allow for the larger size of the 4l85e.

When we installed the adhesive heat barrier on the floor over a year ago we didn’t fill the (approx.) 4”x4” shifter hole - DOH! So yesterday I cut and carefully removed about a 1/2” of the barrier around the hole perimeter and instead of welding in a cover I will use panel adhesive to patch it, cover it with the same barrier on top and some rattle can bed protector on the bottom.

PS: Anyone know if the trans cover was fastened to the cab floor with threaded speed clips or just sheet metal screws?

I got the engine roughly in place, and suspended from the hoist, the trans is touching the cab, the oil pan is barely above the steering rack, and the engine angle is definitely more than 3 degrees.

I'm honestly a bit perplexed, as I've seen trucks here with LS/Flatout and it doesn't look like there was any firewall modification.

In Dan's chassis below, the engine is as far forward as physics allow, as the passenger valve cover has about 50 cents worth of space until it touches the cab.



Dan, I noticed you have the trans access panel off in your can in all of your pictures.. does it fit and you just havent installed, or did you need to remove it? (hope he sees this)
