Id go with the XE 230/236 comp cam. I have seen several street cars running around with this and really running good.

 

I like the XFI cause it is faster under the curve just a little slower from seat to .050" Has good lift. Designed to work great with a 1.6 pro magnum. Here are the specs on the 07-467-8. Dur @ .050" 230/236 with a lift with a 1.6rr is .576"/.570" on a 113 LSA. The step smaller might do even better like a 218/224 and a lift of .570"/.565" on the same lsa.

 

yeah the 230/236 is awsome... matter of fact I know a guy selling a brand new one in the box. for $220.
in the forsale forums.
