Well... to hell with making a foam copy. This thing is gonna fit no problem. I might have to hack the fire wall some, but not any more than you'd expect.
And OoooHMYgod does the Eaton sit perfect on top of the 4.3.
All I should have to do is hack down the back of the M90 just a hair and tig up a square bore plate. Adapt the M90 for the 4.3 LIM; drop the carb on it and call it a day.
As for the size constraints here is the skinny...
The 4.3 is 22" long from flex plate to W/P... The 2.5 Porsche is about 23 ish (I can't exactly see down in there).
The 4.3 is TALL from the bell housing up its gonna be a whopper of 12" and after about 5 inches forward of the bell housing its gonna be about 16" (cause of the carb). According to my rough estimates that puts me at about right at where the top of the rear storage bin would be. Another words this is gonna fit under the glass.... BUT JUST barely under the glass.
