I'm trying to decide which jets for my new 850 BG Might Demon carb will be best. Out of the box it comes with 85s in the front and 93s in the back :eek: but on my dyno sheet where a holly 1000hp was used they used 84s front and back? Should I keep the jets that come with the carb or go to something else? The engine is a 505 stroker, daily driver, will be raced.

Leave it alone, bolt the sucker on there and see how well it runs. They are usually pretty close on the jetting right out of the box. At least the ones I have played with, we messed around and usually were pretty close to where we started.
