Hii
I'm gonna swap my 5.3L engine and put it in the new 6.2 376/515 HP engine from GM-Performance. My car is the 2010 RC gmc sierra with the new 6-speed transmission.
So i was wondering how reliable would it be for a daily drive?
I'm not a racing guy, just some fun from time to time.

The LS3 is a very streetable platform. it has so much room to grow. I say put a nice cam in it with some boltons when you swap the 5.3 for the 6.2.

I've been beating the snot out of my L92/6.2 stroker motor for over 4+ years in my C5 and I've never had any issues. I've tuned several Vette LS3's ad they make nice broad power curves.

i DD mine...its not the 6spd but i swapped in the 6.2 with 18,500 miles on it and i have 5k miles on my new set up roughly. times are in the sig and i still get 19mpg on the highway with 4:10s.

Tho the price isn't listed I'd guess somewhere around 7k+. You should be able to get a 6.0 and punch it to a 370 or even buy a junkyard 6.2 and mod it to 515hp for less.

370ci LSX engines are GREAT street engines with plenty of potential and they really love being Boosted. That is why GM put the 6.2 in the ZR1. It allowed them to increase the boost and have a high horsepower Daily Driver that was reliable and got good fuel mileage.

find a stock 6.0 or a 6.2 for 2500-3500 and put a cam, 1 7/8" LTs, converter, gears and youll have fun
