Better rich than lean at first , get a Holley jet kit / assortment / should be the same for ProSystem Jet kit on ebay or wherever so you can get it in the ballpark so it does not end up costing you a bunch of money to get the right jet/s sizes , also some Holley jets are the same size for the number stamped on them but #92 are like 105 , do a search for Holley Jet Sizes and you will get the chart under "images" how rich is rich? try primary first , I would guess a #84 to start with , it depends on a lot of stuff cam choice makes a big difference but nobody can give you an exact size for your engine , good luck.

#92 is a 105 drill size
#84 is a 99 drill size
#79 is a 91 drill size
#74 is a 84 drill size
#71 is a 76 drill size
#70 is a 73 drill size
