Well 1 down in the front is = to 2.5 up in the rear plus 2 on top of that is 4.5 up..Way too much for stock arm at any HP..I have mostly stock motor Myself and for Me 17-42 is perfect, real close to rev limter right at the line..
I've been 9.34 @ over 150mph in the 1/4 with this set up..and I weigh 185lbs in street clothes..if You have a arm or are real heavy maybe more gear would help,with that set up its going to be hard to get out of the hole without wheeling..And it would be reving alot more on the highway,not less..
I have tried alot of combos Myself..this is a pretty good set up..trust Me!!
