Just bought one BNIB from a member here, trying to decide on what gear ratio will suit me best. I keep going back and forth between 4.10s and 4.30s

My old combination was:

04' LQ4/4L80E, TPiS ZL10 cam (202/216 .525" 112 LSA), 31#/hr 8.1L injectors, airraid intake tube, fbody efans, tune, Magnaflow 20" case muffler on the factory cat back, 3.73s, 31" tall tires.

That truck is totalled, swapping the engine and transmission into the truck in my signature. New mods: Speed Engineering 1.75" LTs, dual 2.5" into a DI/SI Magnaflow with a 3.5" tailpipe, S2 ported TB, and whatever gear ratio I decide on. Might do a NNBS intake swap, as I have access to one from a 2011 truck. I'm thinking it might be worthwhile with the larger cam and freer flowing exhaust.

The truck is a daily driver, 60-65% city, 35-40% higher driving. I tow a trailer several times per year with vehicles on it in the 3500-4500# range. (Trailer is just over 1500lbs)

I'm not interested in racing the the truck, nor am I interested in putting a stall converter in it. I may see how it does at the track once to see how it compares to the old set up, but it is highly unlikely. It is more realistic that I will redyno it at the same dyno in the same conditions for comparison.

Is it worth going with 4.30s instead of 4.10s in this application? I had some mild cam surge with the ZL10 cam and 3.73s in my old truck. (Mostly around 1300-1400 RPM) I'd like to gear appropriately to avoid that and be able to tow well.
