LT or LS for towing?

[Jamie e]

I Really want to upgrade to an LS motor, will that affect towing a boat?

Why do you consider the LS motor an upgrade. I thought the entire model line came with either a 255 hp V-8 or a 180 hp 6.5 diesel. The LS and LT versions in V-8 both have 6,512 lbs. trailer towing. I thought LS and LT were just trim levels unless this is a bot.

I'm talking about the stock LT motor vs. an LS swap.

what year vehicle we talking about here ? there seems to be a bit of confusion on what you are talking about. LS , LT and Z71 are trim levels and are pritty much the same motor and tranny. gear ratios very.

A 1999 2 door LT. Stock motor but I wanted to swap the motor

They are the same.

My last truck was a 95z-71 pick up. It had a 5.7. It towed anything I hooked up too. This taho I haven't towed anything big but I like this so much better than the tbi. To me seems to have more power. But that's just me.my opinion do a swap if you have the means to do so. 6.0. Lq4 or lq9. I am doing a lq9 in my taho soon. Do your research first. I read for a year before getting to where I am now. You will have a bit more work to get it in a old truck like yours. But done right will be worth it.

I would like an iron lq9 also when mine goes. What all is need for a ls series motor, is it a fairly straight foward swap

It will tow it I towed another Tahoe up a mountain on a trailer with my 01 Tahoe 5.3 she pulled like a beast

I am sure it will do it. Just haven't had the chance to do so. New trailer comming in the near future so just want to make sure I have more than enough power to do what I want it to do. And have fun doing it

This swap has been done many times in many versions. 99Tahoe put one in his tahoe. he's near me and was very helpful with my NV4500 swap. Also this guy has a great write up on his LS swap

In any case, read read read. The information is here as people have done it before you.
It's not mechanically hard but the details are in the electronics and computer crap. Keep us posted of what you do end up doing.

an ls motor would be a bit better for power and mileage when towing.

 

[SunlitComet]

They are the same.

[SunlitComet]

nope.

he is talking a gm ls type motor platform in his lt trimmed truck. it is in the details.
