My buddy made 950rwhp with a stock LS3 block, $100 LS crankshaft, $600 compstar rods, and off the shelf Diamond pistons. He runs budget $1400 SDPC ported LS3 heads and stock LS3 intake. $400 cam, $500 morel lifters, stock rocker arms. He runs a GTS76 single turbo and $400 Treadstone intercooler. e85 fuel
Engine weight is around 425lbs without turbo.
You will save hundreds of pounds off the front end with LS power. His engine revs to 7800rpm when needed. 7K normally
He runs a $1100 Mcleod RXT twin disc clutch that has the pedal pressure of a Honda.
No need for TTBigBlock unless its a drag car. You can into plenty of trouble or out of it... running a turbo LS setup.
A stock 6.0 LS shortblock, stock ls3 heads/intake, medium size cam, single s480 turbo recently went 8.65@157mph in a Mustang running a TH400. Imagine what a built up one can do.
I'm hoping to run some 9's with my '69 Chevelle project and if not... I'll put on a bigger turbo.
