410/411 or 373's!?
I have an ecsb with 6.0 and 3k converter. I have 373's installed now but I am thinking of doin 410/411's. What are the pro's and con's of both and a little bit of feed back on trucks with both. Thanks

Also depends if you are planning on going F/I. If I wasn't planning on running a blower I'd do 4.10s. If you are then just beef up the 3.73s and call it a day or else you'll never catch traction.

My truck has 3.73's, and I am debating changing also. I am considering at least 4.30's. I went to the track the other day, and never got it out of 2nd gear. For some reason it kept revving, but I was going 111MPH at 7143 RPM's in 2nd gear. I am running the stock tires 275/55/20's.

I do not plan on going F/I. I plan on heads and cam maybe a little nitrous 
I already dont get traction at all on the street. It has a 2inch hanger so pinion shims may be needed?

Mine hooks at the track but blows them off on the street. Thats too much for me. I do travel on the interstate a little so thats too low lol honestly it felt faster with the 342's. Thats alot of rpm's! I got a 13.17 at 104 but I was deff in 3rd gear. What size cam do you have?

I run a 224/230 cam on 114. I didn't think I was revving that high until I looked at the log. I didn't want to go much past 6800. Yeah, on the street I can spin them easily in first. My problem is 2nd gear just seems a little too high. I would also like another gear to get my times lower.
