hey whats up guys. well i'm new here but i have a 2000 silverardo ls 4.8 v8 step side and i really want to put this thing in the 400-500 hp range well i got an idea of what i would love to do lol swap a ls7 in there but that cash is a little low for that and would probley have to change alot to it. i was wondering what you guy think i should do? motor modds and drivetrain modds that i will have to do since i want 500 hp? thanks alot guys.

 

Welcome to the forum.
You're going to have to work hard, spend $$ to get 500 hp from any engine, expecially a small v8. Your best and cheapest bet would be a 6.0L swap and a big shot of nitrous but even then your going to fall short of 500hp. You'll also need to improve the stock drivetrain to sustain that kind of power.
Don't fret though, stick around a bit, read as much as you can and you'll figure out how to get where you want with your truck.

 

well i dont mind that cash this is going to be a big project for me i bought this truck used and want to clean things up and make it a truck that people have never seen befor it will take time but i will get there. i dont want nitrous tho not a big fan maybe turbo twin or supercharger at most i want to do maybe a ls7 crate motor or just rebuild the motor i have but i cant find parts for it.

 

Do the LS7, that'd get plenty of attention.

 

i would hope but thats 13 grand and what else would i have to change to my truck so everything runs smoth? im in auto body so im not igood when it come to stuff like this but i want to learn.

 

all you have to do is pull your 4.crap out and put the ls7 in it's place, then get a tune to make it run in your truck. once you get that in there, then you can mod the **** out of that engine to make alot of power

 

i dont think my stock tranny and diff will hold up and wont i have to change my engine mounts?

 

The motor mounts are the same, you are right about the stock tranny and diff breaking. If forced induction is what you are looking for, 500 HP should be easy from a forged 402 or 408. If it were me, I would buy a 402 shortblock, call WCCH for heads, and wait for the Eaton TVS 2300 supercharger to become available. That would have a hard time making less than 500 HP, and be happier at 800 or so.

 

dam how much would that run me with tranny and diff add around 15-18 grand? and the 402 is pretty much a ls2 right? and why would that be the better choice? other then more power.

 

Good luck spending less than the 13 grand to reach your goals.
