This is my first LS build and as such, am a total newbie! I have been researching this for a few months now and have just put together a little combo I HOPE makes sence and will actually work!

Can people help me out? any advice? The complete engine is going to be built from the ground up as a stock LS3 over here costs around $7,800 and thats before any upgrades take place. It is much cheaper for me to build from scratch buying parts from over the pond.

I want to run on E85
Looking to get into the 8’s
Car will be 90% track, 10% street.

Where are you? Just curious if this is your first LS build it sounds pretty ambitious. I would check out the boosted forum to see who can help with a cam selection. You could try talking with Arun, he has been specking cams for super charged builds. He may be able to help with a turbo cam.

I am in the UK.

It is ambitious, but I am an ambitious type of guy. It is going to cost me around $7,000 for just a STOCK LS3 where I am, so i thought id spend a little extra and get a HUGE increase if you get me?

As DADDY J stated, this will be going in an 2004 Mustang which weighs approx 3250lbs? the interior will be stripped and some lightweight items added so not 100% sure on final weight, I will also be running MT 275 radials 90% of the time, unsure on transmission as of yet.

Or, if anyone else can assist, I have a budget of say, $15,000 and want to make as much HP as I can from an LS series motor, what options and combo's are available to me?
