Can anyone confirm if the LT1 4l60e and LS 4l60e's transmission mount pad is the same height from the centerline of the trans? I know they are in different locations (LS is further forward) but I'm trying to figure out if the height is the same. I mocked up a setup with an LT1 trans but ended up switching over to an Ls1 trans for the final build. I'm notching/rewelding the tubular K member to accommodate the forward to back difference but I need to know if the heights are the same so I can keep the engine angle spot on. I've bee told "they are close" but that doesn't really help me.

Wondering if anyone knows off hand if maybe they are the same or if anyone with an LT1 trans would be so kind as to measure the base of the mounting pad to some fixed point I can match on the LS trans (like maybe the centerline of the output shaft) so I can compare it to the LS trans. I got rid of my LT1 casing so I have nothing to compare.

Thanks for the help!

 

If you mocked up with one trans and are using another...why can't you measure yourself?

Is the old trans gone?

 

I'd guess it is gone.

 

Yea, unfortunately I got rid of the LT1 casing before I got the LS casing not anticipating there would be any difference. For some reason I was thinking the only difference was the bell housing shape and the different converter depths but figured all else would be the same. Bad assumption on my part LOL

 

Yea you're probably right *hangs head in shame*
