Comp Cams: New LSR Series Cams - 27 new grinds
 

I'm sure those attending SEMA may have seen these or perhaps have more information. Anyway, Comp has released 27 new cam grinds based on custom grinds they have done in the past. They also released a LS series "Thumper" camshaft line. Curious to know what lobes they are using, or maybe it's a new lobe series. They also show the LSR 102mm intake for the LS3/L92 heads and a new set of rockers.

Here's a link to an interview with a Comp rep at SEMA:

Anyone got any info on these?

I can't see the Comp Store for some reason :(

Are these different to the new ThumpR cams?

The 102mm FAST for L92 motors is going to be a very popular item since the stock L76 manifold is such a pooch!

I believe they said it will be available for cathedral ports as well. Should be a cool intake. Put it this way, I'm not going to buy a FAST92 right now until I see what options are available with this intake. Interchangeable runners would be interesting.

Comp have these cams listed on their website but NO specs :emb:
