Default LS1 400-450hp. Whats needed

Hi guys! I have an 2000 LS1 out of a vette. I would like to get above the 400hp mark and ideally be around 450hp. I am currently building a set of long tube 1 3/4 headers 32" long so i have the headers taken care of. Now i read that people recommend heads, and cam but I don't know much about motors and was curious what heads in particular and what cam? I am trying to keep this as inexpensive as possible. Thanks ahead of time.

Josh

400rwhp is attainable with just a cam and bolt ons.

450rwhp will need decent heads

so which do you want?

solid recipe for 450rwhp is something like the TSP torquer 2, or the Futral F14 cam, and some milled stg 2.5 5.3L heads from TSP.

get the compression up to build torque and power.

throw a ported FAST intake on top of it and you'll make your goal with little doubt.

There's a huge list of sponsors on the right. There's also a section of the forum where sponsors offer deals to LS1tech members, and there's another section where members sell their used parts. Shop around a bit.

I just went to TSP's website and the torquer2 cam was 399 and they have a few different set of heads. The 5.3l were 1299 and they also had LS6 ported heads for 1099. Do you think i could reach my power goal by either keeping my stock intake or switching to an LS6 intake? Just trying to keep the money down a little. Thanks

you'll definatly need to change to at least the LS6 intake.

the stocker is horrible in comparison. on a h/c engine you could lose 15+hp through the stock ls1 intake.

to keep price down you're best bet is budget heads, but you'll probably need a bigger cam to make up the difference.

Do the 5.3 heads bolt right on with no mods? better yet does the LS6 intake still match up?
Anyone know the compression ratio after the 5.3 heads and stock LS1 bottom end?

Yes they do and will provide a nice compression bump

A cam is 399, but you should get a spring kit on top of it for 250-300 for the added insurance. Do it right the first time. You'll need a tune, as well.

I love these threads.

There are SO many factors its not even funny.

You want custom cam or off the shelf grind? You want shitty headers or top of the line? That right there can be a 1000 difference.

Are you doing your own mods?

Heads/Cam/Boltons/Dyno tune.

For heads your looking at anywhere from 1200-3000

Cam you could go with a custom comp with springs retainers and pushrods for as low as 600. Or you can go with FTI and spend 950.

Headers you can go with shitty 400 dollar headers or 1200 dollar headers. Hi flow cats is gonna set you back.

Intake another 150-250.

Catback anywhere from 300-600.

Labor- Camswap anywhere from 450-700. Headswap at a later date your looking at anywhere from 400-800 depending on how much they have been decked. Hell you might need new pushrods when swapping heads (I did).

All the mods you wanna do if you got them for dirt cheap and did your own labor.

I had a performance shop do my head swap and cam swap plus dyno tune.

I've put 5 grand into my car and make 435RWHP on an LS2 GTO. Of course if you do all your own labor it will be cheaper. But its still gonna be over 3 grand.

I am building a classic truck so i won't have any cats, i have already built one of the headers and hopefully starting the other header tomorrow. My father is going to do all the motor work so that save me a little money. I am just trying to do my homework so i get a nice setup. Thanks for the help and info! Here is a pic just for the hell of it of my header i built. 1 3/4 primaries to 2 1/2 collector, 32" long primaries, equal length primaries and it all tucks into my frame.
