What's not right here???

Think I've killed two birds with one stone. First two are from drivers side, third is looking down on passenger side.

Essentially, the entire drivetrain is bolted up tight, all the mounts are bolted in tight, and that's a TON of movement. Plus, it looks like the motor isn't sitting level, which would explain the clearance issues I'm having with the turbo manifold on the drivers side suddenly, which would EASILY explain the vibrations.

Is it the motor mounts themselves?

Otherwise idk what would allow that kinda movement?

btw what kind of header wrap do you have on that

That has to be a motor mount. Is your engine assembly balanced?

Looks to be the motor mounts. I can see both compressing and extending with shakes. left side compresses, right side extends a lot. Think the right is sagging pitching the left side up.

The header wrap is the waffle aluminum stuff that APS supplied with the turbo kit.

According to texas speed the 377 LS3 shortblock was neutrally balanced, and I've had the clutch out and verified to be a zero balance too.
