im thinking i want to possibly cam the formula either this coming spring or next fall.i want a mild cam that wont mess up my driveability that much or make me run a higher octane then 93 like im currently running.im seeing alot of f-bodies going with the cc305 and cc306.is there alot of supporting mods to go with them?i guess i can assume tighter springs and a pcm retune.r both cams “mild”.i can tell a big difference in sound between the cc305 and cc306 because u can easily pick up the lopeing of the cc306.but as of right now im just looking for input because im broke so i need 2 start saving if this seems like a decent route to go.
CC305 or 503 would be a decent choice for you. 305 is abit more mild than the 503 since its got abit less duration and on a 114 lsa. I’ve heard a few vids of the 305 cam and its mild if you get the version with 114 LSA. not much lope, but does make ok power. seen guys making 330whp or so stock heads. similar power to if not abit more than the LT4 hotcam but without a lopey idle. 503 cam is a great cam tho and one i’d recommend for your goals.
CC306 is a BIG cam and the biggest you’d should run in a auto car on the street with stock heads. it wants ported heads but will work ok with out them and make pretty good numbers. it lopes alot tho. not the best driveable cam but will work ok. Slowmaro95z28 is going with that cam i do believe. will require all the bolt ons like full exhaust, bigger TB would work nicely, and definately a 2800 stall minimum i’d say. it like 3.73 gears too for best track performance, but 3.23’s-3.42s would work for a driver.
Lt4 hotcam is a fairly mild cam that will still make nice power and put you over 300whp probly with longtubes and tune. could run stock converter probly but really wants 2400-2800 stall i’d say.
all of these cams you can pick up for 100-150 bucks used on fbody forums.
there are more modern grinds out there with very aggressive lobes that will idle great and make better power. Comp’s XFI cams are just that and something i’d go for if you were looking to buy new or had the money to go new cam. something like the 268 cam would kick ass in that car. its a hot setup. TPI siamesed runners guy made 360whp on that cam with AFR heads.
I was thinkin of a cam and was gonna try and go with a comp cams 503 cam. i like that grind and it makes nice power. alittle lope at idle just how i want it. but i may go CC305 for that 114 lsa. It will be easier for me to tune that since the computer will want more LSA.
no point in getting a bigger cam if you dont get a stall to go with it. it really helps get the cams in the power band and makes the car alot faster. else it will feel dead down low. Stall helps with the driveablilty alot.
CC306>
cc306 is very streetable. A buddy of mine ran it in his 93 z28 with a 3000 stall, 3.73s and a 4l60 and then 700r4 tranny. He daily drove it for awhile and even made trips from Nashville to Chicago in it every couple of months.
IMO if you’re gonna cam it, don’t put a mild one in it. lt4 cam usually gets you around ~25 hp at the wheels. and I would only use the 503 cam in a larger/heavier car.
so I say cc306. with bolt on’s, stock unported heads, you might tap into the 11’s. (That’s what my buddy ran in his 93z).
You may also want to check the xfi’s camshafts for the lt1 for more of a selection… comp cam isn’t the only company who makes camshafts.
and to do the cam swap you need the cam, gaskets, springs, locks, retainers, and more then likely injectors (that 93z was at 120% duty cycle on the stock injectors), and a tune.
possibly a new timing chain too, no sense in using an old one with lots of miles on it. they tend to stretch out i hear
definately bigger injectors to. 24lbs wont cut it. 30’s for that big cam
if you like the CC306 then i think the XFI 280 cam will be better. its on a 113 lsa and has more aggressive ramps. I know a few thirdgen board members running XFI cams and they idle smooth compared to similar cams and make more power.
but its up to you. XFI is near 300 bucks depending where you get it. you can pick up a 306 for 100-150 depending
306, but even better yet, grow a set and use the GM 847 cam!!!(just sayin that to get orr all worked up haha)
Do you have any plans to port the heads in the near future?
No.so what kind of ball park figure should i expect for a cc306 with supporting mods.o ya since i didnt see it ne were im assumeing u can still run 93octane??and ne suggestions on were to get the pcm tune?
lol what you guys consider mild i consider somewhat hot. i’d run a 306 in an auto car only if it was a more strip car, but w/e lol 847 cam is MEAN in a 383 tho but on a 350 that thing will rev to the moon if you have the heads for it. good cam
as far as power numbers, with supporting mods and stock heads, most i’ve seen was in a manual car making 360whp with that 306 cam. thats kick ass!
but that all depends on the tune. thats why i’d recommend a 503 cam or the LE1 cam (lloyd elliot) for more bottom lower rpm range power and torque over the bigger 306. Or go slightly larger like the combination motorsports 227/233 cam which is nice inbetween cam. the smaller cams should make just as much power and probly more torque than the 306 from idle to 4500-5000 rpms or so where the 306 might start making abit more all the way to 6000 when the heads cut the cam off
The LE2 cam is like the 306 cam but will make more bottom end torque between 2500-3500 they say which is nice.
if you’re gonna cam, make it worth the trouble. That’s the way I see it
otherwise just add some higher ratio rockers and call it a day
also some specs on these grinds would help out a member who’s not familar with f-bod cam names 
here you go
LT4 Hot Cam — 218@ .525/ 228@ .525 (1.6RR)— 112 LSA — 1800-5800 RPM
GM 12370847 — 234@ .539/ 242@ .558 (1.5RR)— 112 LSA — 2000-6800
GM 12730846 — 220@ .509/ 230@ .528 (1.5RR)— 112 LSA — 1800-5800
Comp cams
CCA-07-305 — 220@ .510/ 230@ .510 (1.5RR)— 114 LSA — 1500-5500
CCA-07-306 — 230@ .510/ 244@ .540 (1.5RR)— 112 LSA — 1800-5800— more like 6000-6500 rpms peak lol
CCA-07-503 — 224@ .503/ 230@ .510 (1.5RR)— 112 LSA — 1800-5800
comp XFI
CCA-07-466 — 218@ .570/ 224@ .565 (1.5RR)— 113 LSA — 1800-5800
CCA-07-467 — 230@ .576/ 236@ .570 (1.5RR)— 113 LSA — 2000-6000
LE 1 and LE2 cams are only known by the ppl that have them and they are not at liberty to discuss the specs LOL its secret
LE1 is similar (at least in terms of duration, not sure about ramp rates) to the 503 and 467 but a tighter LSA. You definitely notice some drop in low end torque with it but not too drastic. Ran a 2800 stall with it, but with ported (LE2) heads.
thanks everyone for all the help.the car wont be a daily driver.but it would still be street driven every now and then and when the beater breaks down.maybe like 01GPGT said i think rockers arms might b my best bet since maybe a 306 might be more then i what want to get into.cause it seems that ported heads r a really good idea and i have a auto and some of u said the 306 would be the biggiest cam u would run if u had a auto.but not much was said about supporting mods for the cc305.with supporting mods and tune would it b possible to c 300 whp?
All cams will benefit from ported heads or aftermarket heads, except maybe a stock cam. But its just that the CC306 and larger cams will really wake up with those ported heads and are designed for more airflow. Their large duration lobes wants to breath more air than stock heads can flow but that doesnt mean you cant use them. they just will peak somewhat earlier than normal and flatline the power curve up top. For that reason it seems like a waste to me to use a cam that wont be getting its full potential.
The CC306 is a good cam and probly the biggest you should go on stock heads. It usually make 350-360whp on stock heads and upwards of 400 on ported heads. thats why its abit better idea to go slightly smaller on the cam than the 306 if you dont plan to port the heads anytime soon.
The 305 with basic supporting mods that all cam cars should have like longtubes, catback, throttle body, airfilter, injectors, and tune will make good power still. I still like the 503 cam more than the 305 for its duration and tighter lsa, but both will make good power and probly be within 10-15 hp of each other. thats not too bad. either of these cams will get you over 300whp easily. you already made 262whp with no headers. you could be near 275-280 with longtubes and a tune. maybe more. cam should net an easy 40whp more. most 503/305 cammed cars i’ve seen make around 330-340whp on stock heads. thats only 20 less than the CC306 in most cars which aint bad since the smaller cam will make better low end power and be more streetable.
