do i just put the passenger side motor mount backwards to where the front of the mount is in the holes where the back of the mount was originally and then drill out a third hole for a where the back of the mount is moves to?

If you're putting the motor in an orignal V8 car, you have to use the clamshells off of the original motor, or if you don't have them you need some for a standard SBC.

i did put the clam shells from the original motor on the lt1 but it didnt look straight to me, plus the clam shells looked identical to the lt1 originals?? i didnt look if there was a way to mount the passenger side clam differently however....

fyi the motor came out of a 94 caprice and the car is an 86 z28

The clamshells bolt up the far front holes on the block

If you look, you can see the clamshell bolted up to my motor here

If you look at this picture, you will see three raised areas on the front of the block where the feezeplug is at, this is where the mount goes

this is weird cause it completely looks like it makes sense in ur car but isnt making sense in mine, im going to check it out more in depth and if i cant figure it out i will try and post some pics

ok i went and looked at it better and found that the emissions tube was mounted on the raised hole for mounting the clamshell in proper location for the thirdgen. thanks

do i have to change the mounts on my block to the ones that were on the old motor? or can i use the mounts that are on the lt1 block??

You have to use the original clamshells from the old motor (If it was a V8)

The pieces on the block are called the clamshell, you have to use the original ones from the old engine.

ON MY 96 LT1 I USED CLAM SHELL FROM A 78, 79 CHEVY 305,OR 350 ENGINE. THE MOUNT CAME OFF A 78,79 ENGINE. THEY WILL FIT LIKE A GLOVE.
