You almost have to wonder if Chevy did a different bell housing bolt pattern on purpose to ignorant, even Cadillac used the the other bolt pattern, kind of surprised GM didn't say use one dam bell housing pattern. Interesting on the LT-1 bell housing, so an LS1 T-56 is much easier to adapt?
Quick time makes a BOP to LS T-56
Interesting, unfortunately everyone has jumped on the 4L80E or T-56 band wagon so either sells quick and for big bucks, so finding one is unlikely unfortunately. Even people looking for Olds V8 have ads up, so they are now hard to find, seemed to be a bunch around not long ago and the 350's were near free. The last Olds 350 I saw was $800! Look for a PM on your 10 to 1 iron head 403. Good luck on your search Martin, your Olds has come a long way.
