So I've currently got a built LS-6 in my car. Puts out nearly 500hp, but a little soft at low RPMs.

There was some valvetrain noise, so I took it to Icon Autosports in Stafford (near Houston).

Apparently a cam lobe is wiped or about to wipe or something or other and the cam needs to be changed.

Now, I know that costs $$$. I eventually wanted to upgrade the engine in any event, so no is probably the time to do it.

Here is what I want: great low-end torque for instant throttle response, good HP up top, and the possiblity to upgrade the HP up top if desired down the road.

So I figure there are a couple of options.

One is to go with a Kenn Belle. I know those things make MASSIVE torque all over the RPM range. But I'm not sure I like the new hood you have to get, they are costly, and I'm not even sure anyone around Houston can install them.

Another is to have an LS-3 or something built. Stroke/bore it out as much as is reasonably possible, get some good heads on there, and put in a cam that is big enough to get some pretty good up top HP but that does not give up anything on the low end so to keep instant power when I touch the gas. Then, if more power is needed down the road, hook up a centrigul (however its spelled) blower to increase power up top even further, but keeping down low torque under control so hopefully tranny/rear end, etc. don't start breaking.

There is always an LS-7 option but I think those cost lots more money.

Any thoughts on the matter? And any suggestions as to possible starting points for a budget build with great potential?

Thanks!

 

When you add up all the costs. You might be right at $20K for that built motor.

In that case put in an LS7 with a dry sump

 

You better start off with what your buget is !!!!
If your cam is wiped you need to start now!!!
The kenn belle and hood is what 7-8k right off the bat?

Well, I don't have a fixed budget - I can afford damn near anything. But I just want to pay as little as possible for great low-end torque and upstairs power

 

I just read on here (tech section) a post from Hinson Supercars for an LS3 427 650 hp long block for under 10k. Or, if no fixed budget, Start with an ERL 500 cid shortblock for around the same price. I've read some great builds off of those.

 

Then go buy a brand new ZR1

LOL, ZR1s are so played out
