-569 rwhp- LS3 LG Motorsports build
 

Looking for a MAX. effort, stock displacement build for your LS3?

This is one example of what can be done when you have a little more room to work than just a head and cam package. We finished this build up earlier this year for a weekend road race Corvette project.

• Stock LS3 block
• Forged Callies crankshaft
• Forged Rods
• Forged Pistons
• 12:1 compression ratio
• LG Motorsports CNC ported LS3 heads
• G6XX Custom grind cam
• LG 1 7/8" Super Pro Headers
• FAST 102mm LSXR intake
• 102mm throttle body
• Tilton clutch
• 100 octane un-leaded

This would be a bit aggressive for a daily driver, but for someone wanting the most from a stock displacement build, it shows what can be done with a 6.2L package.

That should put it roughly in the 655-670 HP at the engine...or 30-40 more than a OEM ZR1

what kind of numbers for 416, your st2 ls3 heads. pump gas

Last 416 we built for a 4th gen Camaro put down 549 rwhp and 530 rwtq through a 9" Ford rear end, that was using a smaller cam than the above package.

Depends on the total combination of course. Generally speaking going to a stroker combination increases HP roughly 10-15 and torque 35-45 at the tires given no other changes.

Price?

NICE!

that is awesome

dang great numbers!

How long till the motor goes KABOOM!

What is the price ??? figured that it was about the same for a 416 build ???? I am looking for a nice big cam, and large dose of gas.

might be a newb question, but how does one go about raising the compression ratio?

Mil the heads , popup pistons

Holy moley! :confused0068:

Why do you say that? It's stock cubes, but all new internals it looks like.

would a boost a pump be needed for this kind of power
