Hi guys ...
my friend has a little problem in which CAMSHAFT he should fix in his 2000 Commodore with a LS1 engine(5.7l) ....

1st camshaft is from Thunder Racing "Split Pattern" - 224/227 .563/.569 114 LSA 2200-6800 RPM Power Band.

2nd camshaft is also from Thunder Racing "TR 224-114" - 224/224 .563/.563 114 LSA 1700-6600 RPM Power Band.

#ps: stock heads
stock torque converter
the vehicle weight almost 2000 KG

What kind of car is your friend building? 1/4 mile? Road Racer? Top End runner? What?

Hi...
He drives a 2000 CHEVROLET CAPRICE SS with an LS1 engine (5.7l - 347ci)
its for street race and daily use

Is he doing any other mods to the car? With a street car I'd probably choose the 2nd cam, but I'd also be upgrading intake, exhaust, heads, and such to maximize a cam change.

P.S. Sarge - like the avatar change.

the first thing you should recommend your friend is to swap out that stock converter. I would then look at going larger with the cam. What are your guys tuning resources like over there? With a good tune a 228 is a great driving cam and can be a nice bruiser on the street.

Not to hi-jack the thread but

what's a good road racing cam, who makes it, at idle are you in a shaker and how much hp and torque is the estimated gain?

A good road racing cam is one that hits at higher RPMs....like the one I just put in my Silverado. Less overlap and therefore less "thump" at idle.

Any initial recommendations on a grind? I'll do some research to refine...

I've found a young kid in the next town with pole barn where I work on my baby (he has frame lift as well).
He's got an 05 he's rebuilding with several forged parts and supercharger. I'm more about rights and left vs straingh line. Rebuilt the suspension with pedders and dropped her an inch with new struts and shocks.

You really need to call Jeff Smith at Comp Cams. Guy is brilliant. Tell him what you got and he will custom grind a cam.
