All cams had a LSA of 110.

However, would a 112 lsa be better for an automatic?

 

Hmmmm...thats promising. I don't think 112 would benefit an auto anymore, EFI but not the tranny (could just be a WAG)

 

I've heard that the 112 LSA would be better for the auto b/c of the wider torque band.

 

Did they happen to print a chart, or graph that shows the rpm range vs power?

 

Yes they did....do you want it....if so I can try and scan it for ya'll.

 

Interesting in that the torque did not very a whole lot just moved up and down the rpm range depending on the cam. Another point of interest is the dual pattern cams did better in the single pattern in the test.

 

Thats generally true, on most heads I've seen.

I'll see if I can find the rag at the store.
