How do I put a Buick 350 into my G-body Cutlass?

I am new here. I have a 1981 olds cutlass. I found a real good deal on a buick 350/th350. Are there mounts for this swap? Has anyone done it? Thank you. Jason

If the crossmember has multiple holes drilled it would not be that hard to fit in.
I would try & use the buick mounts if that would not work you might have to fabricate your own. Trail is the only way if you cannot come across anyone who has done it.
What about GM dismantlers that might know or go down to a wrecker & take a detailed look with some notes.
The rear mount should be OK.

I have a 1984 Olds that I put a 350 Buick in. There was a 3.8 v6 Buick originally in it. What engine was in yours to start? If it was an Olds (would have been a v8) then you will need to change the pedistals on the frame. If you had the v6 Buick engine (which was the standard) then the 350 Buick is a direct bolt in. Good Luck -- I love mine it is sweet.
