Default Can you tell the difference? (before and after cam idle vids)
I know i can even if its a "small" cam

Before: Stock 4.8, Corsa Sport no cats (Cold start, tuned to run after the engine swap)

After: LS6 cam 4.8, Corsa Sport no cats (Cold start, full tune Thanks KYLE!)


and i know the truck is filthy, just drove 2100 miles last week, so give me a break

SOTP feel. Down low seems the same, mid range maybe a little but 4K and up is night and day.

Definate difference. After swap it sounds as if it has a more agressive idlea rather than the smoother mellow idle of the stock cam. Nice set up by the way.

Its gotten CRAZY loud but after the swap i drove it around town for the most part def. makes people turn their heads then with lean cruise tune managed 23 mpg on the 800 mile trip home and going 80 in 5th trying to accelorate it get really poppy and LOUD so a resonator is needed for sure. Also i like the progress i have made on the truck in the last year (was a stock 4.3 just 10 or so months ago) But my setup need alot of work still

No i have not. I know a guy who knows a guy and that guy own a dyno, so im going to try and get it dyno'd soon. But stock through the 5-speed (factory rating being 275(?) minus 20 percent is a measly 220 hp? So i porbubly have like 225 now If i get it dyno'd i post up vidoes (according to thunder550 im a *****)

no way you're losing 20% with the 5 speed.

I'd say your around 250-255rwhp
