does anyone know the dur @ .004 for the comp 216/220?

 

'Advertised duration' is 269/273

Here's CC's catalog page for the LS1 cams:

LSA 112*

Im kinda thinkin this might cut up in the lil 5.3

sound link
also markw gave it a good review in a 6.0 SS
what do yall think?

 

I'd go with Comp. They have a shitload of r&d into the ls1.

Comp

you might look at a reverse split though.

 

That does sound Sweat

 

VHP/Crane have lots more r&d in the LS1 than you think. the VHP cams are the accelerated lift design. it's what you don't see happening after .050" lift that makes the difference. read here: http://www.vincihighperformance.com/...%20LS1%202.htm

Why do a majority of the Vinci cams have a large split in duration favoring the exhaust?

Whats the design or purpose behind it? Only curious because I've heard the LS1 is intake limited, or it plays the part as the restriction.
