Best bet is to get a pair of calipers and measure the actual diameter of the inside of the jet. It is the only way to "really" know what size you have. Just because a holley jet sayes 093 does not mean that it is 93 thou in diameter.
As far as what size is best. Find a deserted road, (better yet a dynojet) go WOT, turn engine off after about a 6-10 sec run at WOT, coast to a stop and check the plugs, if they are black, lean it out 2 sizes and re-run. do this untill the plugs look clean or untill the car surges or lean misses then go back up one size. One size to big is way better than one size to small.
