Need some cam help. . .

They would sound similar at idle. Stay away from the BBR sticks.

I've heard mixed things on the BBR cams...why do you say to stay away from them? I've always like the insane lopeyness (is that even a word? LOL) of them haha.

Although the numbers looks fairly similar, I'd guess that those two cams are significantly different. The BBR cams have considerably more duration, and a slightly shorter lobe separation. If you draw out 19 degrees ( the difference intake duration) on a sheet of paper, it doesn't look like much. To an engine, 19 degrees is pretty huge. Similarly, with the lobe seperation, 2.5 degrees doesn't seem like much, but it can make all the difference to the engine.

In the end, I think a lot of your idle will be determined by your tune. Looking at those numbers, the BBR cams will be more lopey at idle, but some of that can be "tuned out". The BBR may make a little more power at the top end, but I'd guess that the Comp will make more power across the board, due to the dual pattern.

Take all of this with a grain of salt. Although I've dealt with cams in other cars, I have absolutely no experiance with the S197 cams. But if this is a street car, I'd agree with the others and stick with comp. The BBR cams, although the do look like good numbers, seem to be more of a race oriented camshaft. But that's just my $0.02
