i have a 94 k2500 i want to swap an LS into its currently got the old sbc 350 in it with the junk tbi crap what is a 5.3 30 over with a 4 inch crank and is that easy? I found a 5.3 for sale for 350$ high mileage when i get paid i plan on buying it id buy a 6.0 but i cant find one unless someodys willing to sell me a 6.0 block lol

i want around 400ish hp and some lower rpm torque

400 HP?

Cam, headers, tune. Done.

I like the stroked 5.3 idea. That is a cool truck, and you could say 'yeah, its got a 383" stroker'. I have not built one personally, but a stroker will make good torque.
I've got a 6.0 block for sale, cheap, but your probably nowhere near me. I can't believe I can't sell it here locally

I'll pm you

How do you make a 374 stroker?

I have a buddy who is in the process of doing a stroked 5.3, Its an aluminum block with 3.800" pistons and a 4" crank. Should be around 363".

3.86" bore and a 4' stroke.

A stroker isn't required to get to 400HP, but it would no doubt help motivate the heavy truck better with the improved low end torque and horsepower the stroker will offer.

My favorite :

1. A "late" 5.3 Aluminum block@88mm (NOT 89mm)
2. A 4.00" OR a 4.10" Crankshaft with 58x TW
3. A set of 6.125" Rods with good bolts
4. A set Race Tec (Auto Tec) Pistons with NPR Steel Rings
5. A LS-7 (IWIS) single row Timing Chain
6. A 2010 Camaro Oil Pump

The cost VS HP gained when stroking an engine isn't there. Grab a set of heads and a cam and be done.

Or better yet leave it alone and put a $190 Gt45 on it and it will make twice the power on baby boost and a 100% stock engine.

It already needs a rebuild it's at 250k

Bah... we call that broken in the LS turbo world. Your rings will be nice and "pre-gapped". Make sure the bearings are good and your ready to roll.

I plan on driving the tbi 350 wile building this I've never messed with ls stuff and this is my first engine build I just hear the ls is a much better design
