Default LG Motorsports 346ci C5

I know this is pretty classic, but what were the mods on LG's C5 that was supposedly the fastest NA 346ci C5 in the world? I know it went i think 10.9 @ 140 back in 2004.

Lou can probably chime in here, but this was run in his WC car.

This is the cam that trapped 140 mph in the 1/4 mile in a stock cu in package.

535 rwhp 482 rwtq

The engine has AFR 205 cylinder heads with upgraded springs and 12:1 compression.
The bottom end is a forged bottom end with a fast 90 intake and throttle body. This dyno run was using a 410 rear, but we are going to make some spring changes and run it again with a 342 rear.

OH Yeah, LG Pro Long tube Headers, of course.

Stay tuned.

Carbon/Carbon triple disc racing clutch. Its either is cold and slips, or its hot, and when you lauch on a sticky track, it breaks the rear end. Lou broke 3 or 4 diffs in 1 day trying to race the car.

would a factory bottom end with aftermarket rod bolts be able to handle that setup?

Factory crank will hold. Your pistons and rods are give or take....
