I'm testing the BSP-3 in two engines on the dyno and track (sprint asphalt) with somewhat similar results compared to the CL-1i & BSP-2. We're getting up to 6500 with a weenie pipe (about 200-300 more than other two cams), seems fair on the bottom, good mid range and top end but still basically on par with the 1i and bsp-2. So far, we only have minimal testing time invested into this particular cam and it may have more in it than we've found initially. The CL-2 is a whole different story, definitely not a "throw it in and run" type of cam but if you give it what it wants it'll make you happy.
The bsp3 is whats in my motor, and i have had pretty good luck with it and make great power. With any cam you choose to use, you need to match up the carb, pipe, and timing to what that cam likes if you want to make the best power with it. Your best bet is to do what dover said he does, and try different pulls with each cam in your engine, and see which one makes the most power for that engine with those particular mods.
