New Rear Gears

cwatts said

Thanks Craig, just bought new super stock springs and new offset hangers as well. I think I'm going to buy the whole chunk brand new from Mancini here in Michgan and go with the 4.10 and keep the 3.23 chunk if I'm going on a highway trip. Also eyeing up a set of roller rockers good for 25-30 horse.

I had 4.30s in my Demon when I was running a 29" tall tire, now I have 3.55s with 26" tall tire. Both ran about the same 3000rpm at 60mph. I didn't enjoy either on the hiway that much, especially if you needed to do 70mph. I just cruise in town 98% of the time anyway. I run a 3200 converter, which is lots on the street for this torqey stroker. If you want some more low end grunt then try the 4.10s, you will find out soon enough if need more stall, and even if you do you'll still be quicker off the light then you were.
Are you going to do a cam swap at the same time as the rockers? I've never heard of rockers freeing up 25-30hp, I doubt you will not much difference, especially if your build is mild.
