If I was starting from scratch I'd get the Earle Williams LS mounts.

Note you'll must likely have to notch the K-member for the oil pan... I have his mounts for a SBC and I am switching over to a LS (although I'm using adaptor plates vs the LS mount he also sells for the frame mounts... My measurements where showing that the oil was going to hit. Called Earl and he said most times the K member needed to be notched.
