355s to 373s worth it

Already have 355s from previous owner. Don't want 410s cuz it's my dd and I'm poor lol. Would 373s be worth the $255 and could I do them myself with a press and airtools? I have plenty of mechanical background. Thanks

I didn't notice enough of a difference going from 3.27s to 3.55s and it wasn't very noticeable to me. Yes you can do it but when I was deciding what gear to go with I went with the 4.10s.
As far as the tools you're gonna need an in/lb beam type torque wrench, a tool to set the backlash, and a press for the bearings.

Thanks man I would do 410s but do a lot of highway driving. But do you think I'll feel a difference between the 55s and 73s?
If not i have a few other mods I could spend the cash on

You will feel a pretty big difference. I went from 3.73 gears to 4.10s and I felt a big difference.

You changed .39 in the ratio. Going from 3.55 to 3.73 is only a .18 change ,so it won't be as noticeable as going from 3.73 to 4.10. Less than half the change.

gears before headers. You will "Feel" the gear difference. The headers will improve exhaust flow a little. stock shorties are pretty good to begin with. long tubes will require new mid pipe and a tune. and if your broke, i would not start there. It will really only add to 1/4 mile time really. maybe a bit of difference in 0 to 60. that was my understanding of it anytway.

but the higher gears will bring you to higher rpm at lower tire speed, meaning your getting to your power band quicker.

oh and i forgot, the header install is a pain. need to lift the engine to install.

A different sidewall height on your tire could bring a bigger difference in overall ratio than a .18 gear difference

Maybe I'll just get a tuner from am for now. That way I can be ready for future mods too. Rn I have sf connectors, 355 gears, or x pipe, super 40s, k&n filter and 275s in rear. Only other mods I really wanna do is tuner, longtubes, 3.73s, and fr springs. Do yall think any intake parts would be worth the money for a dd? As of now I have stock intake except for k&n filter and snorkel removed. Doubt I'll worry with Udp or driveshaft I don't think its worth the cash what do yall think? Stock intake good for as much as I'm doing or will a plenum or cai really add some sotp with a tune?

A throttle body and plenum like the trickflow setup or accufab would do you well. As if you read up on it that is the "choke point" as some call it with these motors. You will pick up throttle response and a little power. Since you have the 3.55 gears I would stick with those since a 373 won't yield enough of a difference IMO. Get a tuner and a throttle body/plenum combo and you will see and feel some Nice gains.
