I am trying to figure a rear gear ratio that will put my car more in the 6500 range at the end of the track. I am just trying to stay in the power band for my car. As it is right now I am crossing the line at about 5300 with the 3.73 right now and that just isn't cutting it for me. I have only seen two gear ratio that they make for my car that I would consider and that is the 4.10 and 4.56. From the calculators I have tried, the 4.10 would put me in the 6000 6100 area and the 4.56 put me right on the mark at 6500. The thing is I know you just can't go by calculators there has to be other factors involved, like converter slip and what not. The car pulls past 6500, actually there is pull all way through 7grand but I am not uneasy with that rpm. Does anyone have an idea what kind of rpm I would really be at the end of the 1/4
with 26 inch slicks and a set of 4.56 rears 3000 max stall.

I guess I should also add in that I am running a 350chevy - stock 442 2004r and stock 8.5 one-legger with a best of 12.2 at 110. best 60ft 1.7
