thanks 4 all the helpful info..
will just try doing what Killer1200 says and see wat sorta bhp i get. IS there a site that has specs etc for Lseries cams??
The problem with building one motor then building another is the lack of L20b's is the island. So far i have only come across 1 and thats the 1 we have. WE have plenty L16's but the 1600 grp is kinda hot now wid the Jwrc ignis

,so dont really want to go there.
