After third try, LS3 STILL won't go in

[ModernMuseum]

Ufh...after the third weekend in a row, this thing still won't go in. I think I'm going to rename this project "Hopeless."

Vehicle: 69 firebird
Engine stands: 68 camaro?
Engine: ls3
trans: t-56
Adapter plates: s&p
Energy Suspension Mounts 3-1117G

It appears that either the engine stands or suspension mounts are incorrect for the application. As you can see from the below photos, the engine won't go all the way down onto the stands. The stands appear to be too narrow and possibly a little low, so the engine is getting wedged before it will sit down.

I guess if I can't procure the correct parts to get this thing in, I'll have to bag everything up and take it somewhere to get some custom mounts made.

See below photos:

Friday night was wasted after I figured out the adapter plates wrong installed backwards, which came pre-installed when the engine arrived. Thanks Prodigy Customs After taking the plates off, I noticed that S&P even engraved what side they go on. Geez.


Ufh, anyway, today, after lowering the engine as far as it would go, this is about as far as it would get. Passenger side:


Driver's side


Passenger side stand installed (the partial mount on the right is what came on the car....I won't be able to remove it until I compress the springs since one bolt holds the A-arm on):


Both mounts installed





Am I doing something wrong here? Any help would be greatly appreciated. I think my buddies are getting kind of annoyed coming over when we start putting things together only to figure out that we have the wrong parts or things won't go together correctly.
