what can i mod without breaking or tuning
if i get a sponsor to build my transmission and it strong, got a shift kit, etc. will that make my 120k mile lt1 die faster? will it not affect it? should not need a tune.
what about stall converter, do you need to have a tune after installing one? (3200-3600)
what about rear end with gears? (12 bolt w/3.73)
i have a lot of work to do to the car and i would like to get some of these smaller things out of the way before doing the engine.
The Tranny won't make the Engine die faster, your foot will.

You may need a tune after a Stall to adjust shift points and lockup.
3.73's will work well, a 12 bolt isn't a small thing to take care of..that's about $2k..if that's small to you then help me out..lol
You will need a tune for a new stall, Yank SS3600 seems to be a popular choice.
Gears won't necessarily need a tune if you don't mind your speedo being way off.
Heads/cam swap is my favorite mod, but you definitely need a tune for that.
if you have a stock 4l60e with 120k miles a stall will not be a good choice unless you have money set aside for a rebuild imo

ya i plan on doing a rebuild but i want to do the cheaper stuff before that. i would consider $2000 for a rear end cheaper than $7-8k for a rebuilt engine yes no?
i have exhaust, soon to be headers and CAI. guess i can save up for the trans too since it wont hurt my old engine much.
ill have to save gears and stall for the rebuild so i can get it all tuned right.
im hearing people mention springs a lot guess i will have to try them out

$7-8k bottom end would be pretty epic
there are no performance differences between CAI right?
summit has a Trick flow one for $190.
the SLP one is $280
i like the idea of the slp being steel instead of plastic and it has 2 filters instead of one, but its not worth 90$ more

also the trick flow one at $190 is still best bet unless someone sells a used one for cheaper?

Get the factory tune out of that PCM!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Anyone that wants more performance knows that something is going to fail a tranny mount will be the least expensive,Lt1s are old now so expect some failure
Same for the transmission from a sponsor here.
If i have problems then why are they even sponsors, why should i not just go to a local shop and let them ruin it?
Did you talk to someone and didn't like the conversation?
Me personally I do my own work but that's because I like to see it go together and I like to get in there and learn about the stuff I'm messing with. That and a majority of my work is custom.
