Ok so I've decided to build an all motor ls, and Ive set a realistic goal of 150-160 whp. Im gonna go with b16a pistons, dc 4-2-1 header, skunk2 intake mani, and a good set of cams w/adj. Gears. I have some questions on about cams though, I've read quite a few good things about crower 403's but when I go on crowers website i see different part numbers listed rather than the 403 and 404 everyone talks about. I found the ls cams on their site and I think I want to go with the "stage 2" N/A cams, part # BC0022. Does anyone on here have the bc0022's? And what's all the talk about 403's? Are those like old skool crower? I'd just like to know how much power they are going to make before I buy them. Thanks in advance guys.
