LT1 engine mount help

[JerryL27]

Can anyone tell me which motor mounts do I need to mount a LT1 into in 1983 cutlass. The engine came out of a buick roadmaster

 

[DRIVEN]

Any Gbody mounts for a 305 will work.

 

[lenny2001harley]

yes any 305-350 g-body mount will work

 

[JerryL27]

Can I still use the stock brackets on the engine or do I need to get them for 305 also

 

[DRIVEN]

Not sure about the driver's side but I'm pretty sure the passenger side won't work. It's upside-down and different shape IIRC.

 

[JerryL27]

I got some brackets off of 350 vortec block will they work with the gbody mounts?

 

[DRIVEN]

I believe so. Not 100% sure.

 

[JerryL27]

I got the correct frame mounts now I need to get the right mounts to bolt to the block

You should be able to use any small block engine side mount (exc the LT1 pass side). The L31 Vortec brackets are the same as the older style. Keep in mind, you will have to remove the rear AC bracket because it bolts where you need to put the motor mount.

Ok I got the the lt1 brackets off and the vortec brackets on is it any certain way I need to bolt the mounts to the frame I see the passenger side bracket is upside down
