Engine not sitting flat

[AA-ron]

So this is a bit embarrassing, but I've had my engine installed for a few months and it wasn't until I test fit the body this weekend that I realized it's not sitting flat (right to left). In my defense, my garage floor is off a bit.
I measured it and it's 1.5 degrees off tilted to the driverside. If I'm able to live with it cosmetically, and I good to go, or are there other problems that I should be aware of?
I checked the mounts, and unfortunately, the pin in the driver's side mount is already up against the top of the slot, so the only way to level the engine would be to add spacers.

Check the headers/side pipes from the floor up and equalize them. That's the important measurement. My engine was titling to the PS. I ended up grinding the pin slot on the bottom side to allow the engine/pipes to level out.

Following. I added some washers to level mine, but I wasn't sure whether it is necessary.

1.5 degrees! It’ll be fine. You know that roads are crowned, right? And in your case you don’t have to be concerned with sidepipes. Carry on!

I ground my pin slots a bit as well, just to allow the engine to settle into the chassis smoother.

I'm not sure if it was my SN-95 bellhousing or not but my install was a bit of a bear. There was this vent looking thing cast into the bellhousing that stuck up about an inch and it was hitting a crossmember. I ended up taking the PS mount off the engine in order to get the whole works back far enough, then I rotated the engine CCW to get the DS mount stud in the slot, then I raised the engine up a few inches and reinstalled the PS engine mount while the stud was already in the chassis slot. I had to take the whole works out for some small clearancing, but when I put it all back in the pins settled much better. I only took about 1/16" out of the tops of the slots on each side.

It is not unusual to need to grind the slot or to need to add washers between the mount and the block. But usually that is done when the pipes are different heights. If you don't have side pipes, I'd put the angle measuring tool back and forget about it.

These answers were just the ones I was hoping to see! I didn't really want to "need" to level the engine. And in references to Jeff's post, I'll just tell everyone that I intentionally tilted the motor to account for the crown in our roads. Good thing I'm not planning on driving in England...

I would say it's to compensate for the engine torque, it's level when under acceleration which is how a Cobra should be most of the time!

It took a long time to find this photo from the old forum and Photobucket.

An old-timer that was a retired auto & forklift mechanic taught me this trick:

Loosen the motor mount nut and raise the block with a 2x4 and a jack. Use a C-clamp to nudge the mount down.

Wedging the mount DOWN makes the engine go UP on that side.

Of course, this is only for minor adjustments. As you can see I must have lowered my clamp 1/4.
