looking at the specs at these two, what is the difference? the duration and lift is close, but one is 112 lsa and one is 114 lsa. what is the difference in 112 and 114? looking for a good cam for a bolt on stock headed car, and ive decided to go with something better than a hotcam. i want a cam that will sound good, but will give good numbers. also i heard something about one of them you have to change out valve springs ever 20k miles, cant remember which one though. any info will be greatly appreciated.

 

Everyone seems to like the 224/230 or the 503. And with the right spings i dont see why you'd have to change them every 20K. It's not that much lift. Some 918's would be good.

 

im pretty sure im going with the 503, been reading some good things on it in the past few minutes, someone said it in another post somewere, i think it was the cc305, but i cant remember, lol.

 

another quick q, what would be the best valvesprings, pushrods, lifters, rocker arms etc to run with the cc503?

 

i have a cc503 with crane 10308 valve spring kit, comp hi tech PR's, stock lifters, and GMPP 1.6 RR. the set up works quite well and sounds good and runs strong. it's a great cam for stock heads, however i have heard it really wakes up with a set of heads. i'll know for sure next weekend when i install a set of GTP heads on my car. i can get you a sound clip of my car at idle if you are interested in hearing what it will sound like.

 

the difference? you switch the numbers around

 

yea, thatd be great!

 

The 112lsa on the 503 will lope better than the 114lsa.

 

thats what i was thinking, but i wasnt sure, thats what i want though, a good sound as well as power

 

going from a hotcam to a 305, you wouldn't see much of a difference- if any, in sound.

think about it 218/228, .525/.525" on a 112, vs 220/230, .510/.510 on a 114.

the *slight* bit of extra duration will more than be muffled by the extra 2* in LSA...

I've got a 503 on 1.6's in my car, absolutely LOVE the sound, and can't argue with the torque either... idles great, even at 800rpm.

go with a 503, you won't be dissapointed

 

here you go. sory for the poor sound on the revs my camera can't seem to record that well for some reason.

 

thanks alot man, i was thinking 503 but im set on it know. car sounds great btw!

 

thanks for the advice man, ive decided to go with the 503, i want something better than a hotcam, lol
