Keep the spray low, NOS does not like high compression, unless the bottom end is real strong and was made to take the hit. The cam may not work with it either, the juice works best with a 110 or better overlap, and alot of exhaust duration. You might think about a small 75 or 125 max shot. Just go easy, if it wasn't built to take it, it'll let you know. That's my 2 cents worth.
