LT4 Cam VS. CC503 alright i live in CA so i want to stay smog legal, i heard both of these cams will pass smog.......i am on a really tight budget so i may not get the head work done right away (porting and Polishing) I saw a guy pulled around 300 RWHP and 300 RWTQ with the LT4 hotcam kit on a 94 z28. what would the cc503 cam put me up to with 1.6 RR and upgraded valvetrain with no port and polishing?
I like my hotcam, even though i'm about to go bigger!!! ..... but is around 350hp.... and the cc503 is bigger than the hotcam, but don't expect to much out of either. Mine is at about max power with the hotcam.

I've seen peolpe lay down 350+ to the tires with bolt ons and the 224/230.(M6 cars) I purchased one for my 355 but when i got my heads back and talked to Lloyd he said the 234/242 was a more fitting. I'm happy it's not another "can i put a GM847 in my Stock heads and bottom end car with 100+ on the clock. Good Luck

dont get the cc305!! it sux i had it then i went to a lt4 hotcam which was better!!! then i went to a cc306 which is the **** on lt1s!!!! i felt wat my power and top end,i sold my car and got me a t/a now im thinking of going with a gm 847 which is a bit bigger and the duration on it is cracy so its ganna sound choppy as hell!!!
I've know most to upgrade from the Hotcam to a (503) 224/230. anyway, There is also a Lingenfilter 211/219 in a 114 that makes a GREAT smog cam. Look into those. Just dont go bigger than a 230/236 and plan on passing
I take it the 847 is even more cam than the 306??
That sucks about smog. CA smog just blows, one of the reasons I won't go back out there. Gas must be even worse than last year I imagine also, I was paying around $3.63 for a gallon of 91 when I bailed out of there last August.

I am putting down the numbers in my sig with the hotcam. Of course I have a built motor on high compression but when I was just full bolt ons and a hotcam kit I put down 335 to the rears. I don't have to worry about smog so I am going with the GM847 soon but the hotcam has been true to me for 5 years now. A very good daily driver cam and have had no problems with it. I would vote for the Hotcam.
