helix the 720 team is your best bet, the 70-46.46 works good but the newer tri angle helix works better in the midrange.
you will poss find that you have to go back to 10-68 with this helix , it may not pull 7800~7900 rpm.
gearing i would gear down some , 24/42 works good you may not loose any topend . if you not worry about top speed drop a tooth off the top 23/43 , this will still run itn the mid 90's for top speed.
440 main jet is good for sealevel at -10 maybe -15*f with a gutted box and a slp single.
