I agree with hemirick, the isolators are rotated 90 degrees from where they should be. That is what is pushing the block too far forward.

Actually, if I were to rotate the biscuits 90-degrees, it would move the engine farther forward, not back.

Here's a picture I found of a guy pulling his 440 from his Dart, used Schumacher mounts (I think), shows DS orientation. Thread from BigBlockDart

I just looked at the Schumacher directions on line and your pictures. First you do have the mounts on correctly, they should be behind the block ears and you can't really swap them side to side because of they appear to only have 3 holes and one one would end up not being used on each side and you would have used only 1 bolt instead of 2 on the forward mount . First you should have not modified the trans mount as said , the trans locates the engine front to back , change the trans mount to one that is not ovaled and go from there . Looking at your drivers side picture the rubber mount is not 90* to the bracket, everything I saw says it should be and it doesn't look like there is a big enough notch in the K frame mount for the oil pump. I'm not sure about the pan but the Pro parts headers were NOT designed to be used with the Schumacher mounts so any dimpling that needs to be done does not surprise me. I'm pretty sure you would run into a ding here and there with them on a motor plate , I have yet to see any set of headers that didn't need a whack no matter who made them and what they were installed in. If anything I would be slotting the holes on the K frame to make it fit based off correct trans mounting. As close as things to begin with, if the trans mount was not modified then the headers would probably clear, pan to, change that and work from there.

Is it possible that you have a 66 or older a-body k-frame in the car? The early k-frames located the engine about 1-1/2" farther forward. Just an idea.
It would not be possible to get it in there (narrower frame) and they look completely different.

That's exactly my thinking. I'm pretty certain that, if the tranny mount holes lined up, the other clearance problems would go away. Slotting the holes in the K-member seems like a solution, but then the rear edges of the insulators would really be hanging out way past the rear of the K-member. Maybe that ends up just being an appearance issue, but I'd like to avoid it.
The only other thing I could come up with is that maybe I have the wrong set of Schumacher mounts. I would guess that the /6-to-B/RB mounts would be way different and wouldn't install at all, though.
I think we've established that the mount brackets are installed correctly (thanks for the pics, CrazyD).

Slant 6 drivers side mount is the same , Pass side is different so one braket would be right the other would be different and off by a lot .
I was going to ask what was meany by RECONDITIONED K frame ?
If you don't [Edited by Moparts - Family Friendly Site - Keep it clean] too much of the insulator hanging off , I really not impressed wit hthe way they are to begine with , then I'd weld a small platform , if you well , so there is more support under the biscuit ...
Or just use Elephant ears ...
The more I look at these mounts the more money my spare factory big block K is worth ...

I think "reconditioned" is a fancy word meaning cleaned and re-painted, and maybe fixing up the scratches on the bottom. I didn't buy it - it came with the car. But there's no way it could have been modified to affect the motor mounting. It all looks totally stock.
A motor plate is sounding better and better to me. I just wanted to avoid the vibration. I'm sure I couldn't afford your factory big-block K-member, but how much would you want for it?

Based on the thread a little background might help. First the ProPart Headers were designed in the '80s and like CPPA these headers were designed based on the old Direct Connection motor mount platform, at the time really the only big block set-up out there. As you recall these mounts while a great design caused the motor to sit about .75" too tall. Remember all the complaints about the fenderwells and 727 trans hitting the floorboards? - thats what that was all about.
I find this quote to be quite interesting as I have been building DC k-members for well over twenty years and have seen quite a few originals in use. We have had no trans tunnel interference with the 727. The motor does not, in my opinion, appear to be sitting too high in any car that I have built. Nothing against Schumacher, but I'll keep building DC k-members (as long as I can still find core k-members) and building them without all these fitment issues that seem to crop up with other systems...

I too like the D.C. style K-member. never had any fitment issues, have done 3 separate ones so far. using regular manifolds, pro parts headers and Schumachers headers too. 2 cars were 4 speeds the other an automatic 727 of course, the k-members are getting harder to find.
