I realize a lot of people run the gt2-3 and several others that are similar with FI, but I want to try something different. Out of the two cams listed below which do you think would work best with my magnacharger set up making 7-8 lbs? My other mods are in my sig as well.

Comp cams 212/218 114 LSA w/ .522/.529 lift on XE lobes

OR

Comp cams 220/224 114 LSA w/ .581/.581 lift on XER lobes

 

Neither, you need a wider LSA and more split if you dont want to bleed off boost.

There is a reason the GT2-3 is so popular, as well as the vinci trucker, which you may like.

 

The first cam looks fine, thats pretty close to what a friend of mine ran in his 4.8 and put down mid 400rwhp.

 

I have bought a 220-230 XER on a 116 lsa for the procharger.

 

the LS6 cam seems to be very popular with FI apps. So is the cam from EPP (Exotic Performance Plus). Those seem to work for most blower or turbo apps

 

Either one will work fine.

 

With the stall you are using, I would think the second cam would be more suitable. I agree that you need a wider LSA for your FI and would not use anything tighter(less) than a 115 LSA.

 

This cam in Steve's stock bottom end ,stock heads, LS2 AWD TBSS on 10psi is way below 115lsa its on 112lsa so Im not sure why you think tight lsa dosent work with superchargers.... 11.5@120 up here at 4500ft elevation. I would say tight lsa cams are not for everyone but believe me they make plenty of power.
