Need input!
 

Hey guys, that show car of yours was awesome! Anyway..., I've got an 84 C4 L83 Crossfire. The car runs great, has 112k, runs Mobil 1 synthetic and uses no oil at 3k miles so far. It is stock. I don't plan on going into the motor anytime soon. However a bit of a performance gain would be nice.I looked into the X-ram(they're here in Houston where I'm at), but have since read many less than stellar reports from folks who tried it. I've since found out that I can get away with a carb/intake swap and stay legal here. The cam seems to be something along the lines of 405 in/ex and 114 LSA-can't find duration. what would y'all suggest? The exhaust has flows though I don't know if it's a "cat-back". Any input would be nice. I'm not trying to build a race-car, just optimize what I can without going into the motor. Budget is a concern at this point. Also, how do y'all feel about 1.6-1 roller rockers with a carb intake combo-worth the effort?

Thanks much:
