4.10's or 4.30's ? stock 6.0L
235 237 599 602 112+2 cam.
5000 stall
3480# raceweight.
i had a 3.70 in the car, and picked up 8#'s going to a 4.33.
alan futral cut my cam and told me it was a good midrange cam for ET at the track, not a dyno queen.
4.33 was used and whining, so i need to replace it.
id like to get some of my cruising back by lowering it down to a 4.10.
anyone have experience in this case?
20 points to drop in a gear is a lot, but im not sure if my motor really needs to buzz up.
?
thanks!!

I have the same question although I have a different setup. I have an m6 346 ls1 I am planning on installing my trex cam in the near future with some heads. But I want to try to get 11s SI and I was playing around with the calucator and I think I can get 4.30s to work with si will it be too much gear? I am afraid that 4.10 will be to little gear for the trex when it goes in any advice??
