Re: LS Swap Question

What gears do you have now?
My C30 with 4.10s turns just over 2k at 65mph..I like it there..
On the IH I'm building ,I went with 4.56s and a 255/85-16 tire..should put it in the same rpm range as the C30..
for the next one I'm building, I already have a set of axles with 3.73s..it will also get the 255/85-16s....I'm going to try them and see how I like the 3.73s before I decide to do any changes..
all these trucks have/will have LS power and manual 5spds.....
