I'd say 88's sqaure and read your plugs after a shake down run then work your way up or down depending on et's, but either way you go I'd stay square.
Your gonna want it a tad on the lean side for consistancy.

I AGREE. I had a 950 HP when they first came out and it was 78 square and I took the rear power valve out and went to 88's and my plugs were always nice and brown...but I never shut it down at the finish line either...but It ran well.
