The RR had a nitroused, INDY head combo. Don't recall how big. I think 8.80s was about as fast as the RR ever went, but don't hold me to that. Bill went to B-1s in later years and then the smallblocks, but I think the Avenger was the first car for either of those combos to be run in. I am sure Leon and Andy remember some of the particulars here as well.
