Why would you assume...that leads to false assumptions....even if he did h/c/i He will NOT have lots of horsepower...what around 280-290rwhp on a good day....thats not alot....400rwhp is alot...4.10's will be perfect even with that amount of hp(300rwhp)...Its when you get 350rwhp and above 4.10 then might be too much gear. even then youll only go faster with 4.10's on the track...dont fear the gear.
these arent high rpm cars so of course it will be boring above 5500rpm, they stop making power at 5200rpm. My car went 14.5 with the same mods and 3.55's... then went to 4.10's and the same car cut 14.0's....3.55's are weak gears for these cars. go atleast 3.73 or go home...dont fear the gear youll regret it when you h/c/i car runs 13.3-13.0's with 3.55's, when you could be in the 12.8 range with 4.10's.
Even if you run out of 4th gear in the 1/4 mile Due to "too much power" and you have 4.10's... run a taller tire it will do the same thing as running less gear, run a 27" tire, it will make those 4.10 feel like 3.90's...28" tall tire will make them like 3.73's...see you have room to grow with your hp gain in the future...haha on that " alot" of Horsepower 302ci h/c/I car pushing a WHOPPING 290rwhp, yea thats alot of hp. lol, not really
BUT if you mess up and put 3.55's there no fix. you cant run a smaller tire, youll have to run a 24" tall tire....IMAGINE that....youll have to spend 400 on another gear swap, to do it again...something you should have done right in the first place, not have feared the gear. go 3.73 or 4.10 for a manual 5-speed car...
Now boosted that a different story, and depends on blower type also, centri go 3.73/4.10 in manual car Kenne Bell go 3.55's and turbo cars go 3.27 or 3.55
