You should be able to hit high 12's or faster with a hot cam and 3.73's. As long as the motor is in good shape, it'll at least trap up there where it should near 110. It's just up to you to cut a good enough 60' time to get there.

If you're really worried about not getting there, while you have the heads out, give them a good port job for about 500 bucks. This will assure you of low 12's. You may want to consider the cc305 or something a tad bigger than the hot cam to take full advantage of the heads. If I were you I'd port the heads no matter what, just because they're already out from the cam swap, and they won't detract from driveability. If your motor is in good shape, you may even want to consider the cc306 if you port the heads. Even a 306 will be a decent street cam if you tune it well. just my 2 cents

i decided to get a CC305 cam and 1.6RR what else should i get
(like springs, lifters, push rods etc. what else should i get for it to make it complete...brands too when listing parts)

 

how much of a diffrence would that cam make

 

12.3-12.7 depending on conditions and driver.. my bolt on car went 12.5 with some weight loss done.
