How much room do I have to shim the drivers motor mount for headers

[Corvette95]

How much room do I have to shim the drivers side motor mount for the OBX headers to clear the steering shaft? I am also coating and wrapping them in titanium wrap so I will likely have to dimple them too. What shim size (max thickness) can I use without engine touching hood? I know it is close already. Thanks.

Of 5 ZR-1s worked on by Wazoo, none needed shimming. 4 were Stainless works and mine was OBX. Apart from shorter length to accommodate fake cats, OBX runners are almost exact duplicate of Stainless Works.

Thanks, I have read posts saying both yes and no, most requiring a dimple at least. I know mine are going to be thicker due to the coating and wrap.

check the health of the motor mounts... I hear they can deteriorate, this would drop the motor down some... worth a check if you are in there

Mine only required dimpling #1 tube by the steering shaft. I used the Maximizer headers that are the same as OBX without the polished finish.
Good Luck

Keep in mind it's possable to push the engine over to the right a few mm if necessary before tightening the mounts down.

Thanks, would this hurt the driveline tolerence, I currently have the C-Beam off waiting on C-Beam plates from Bill B.

Just another data point, a few months ago I noticed my low mile mostly stock car (no headers) probably came from the factory this way. Pic shows engine mount full right of the slot.

I went to do my motor mounts today, the were like your already as far right as possible. I had planned to reuse the OE heat shields but they looked rough so I am waiting for heat shield material to make my own shields. Should be here Friday, the passenger side seemed not to have any shim at all, I did not remove drivers side yet.
