DD cam
Basically i want something with gobs of low end driveability. The car in question is a 97 camaro lt1 6spd. Right now i have a full le2 setup with supporting mods and a 228/236 cam which just doesnt feel good driving around. Surges and has no ***** on the low end.
I know the cc503 is a trusted and very well used cam. Im just wondering if ill be happy with say that size of cam with my le2 setup. I dont want to be spinning past 6200 rpm max. I want my low end torque and power back. The car will NEVER be a drag strip monster. Maybe the odd trip out there once in a while. Other then that it will be a dd and thats it.
From what ive been reading through numerous threads is that i will more then likely be quite happy with the cc503 cam.
Suggestions/opinions welcome. Thanks
Car specs
Stock bottom end
58 bbk throttlebody
LE ported intake
37 racetronix injectors
Comp 1.6 rr and pushrods, lifters etc.
Le2 cam 228/236 .592/.592 110lsa
LE2 heads, patriot golds etc blah blah
Car will be getting a 24x swap in the next few weeks.

Have you had a dyno tune? Just something to think about. It may help your low speed cruising. If you are just completely wanting to change cams I'd give Lloyd a call. I'm not 100% sure but those le2 heads are better for mid/top end power.

However i still dont want to have to be spinning it as high as the cam needs for it to be happy so i still imagine im going to be changing the cam.
6speed . 3.42
So more or less if i keep it around the specs of the cc503 i will be the happy camper i once was
Edit: Specs in OP

I have no intentions of changing the rear gears, unless mine blow apart, which is likely since i drive like a douche. However at most the car would see a 3.73 probably.

Its your gears. That cam in mine with worse heads than LE2s drives around fine with no surge and I have 2.73s at the moment. The consolation I have when I floor it is the 3600 stall so it gets into the powerband quicker. If I were you I'd leave the cam in, get some 4.10s and a tune from someone reputable (Ed Wright, PCM4Less). My friend is like you, he makes 403/389 through a cam only LS1 6 speed with a 232/236 .592/595 112. He also has 3.42s. From a dig we ran up to around 110 and he still couldn't pull around me.

Hitman is right on the money.
A dyno tune doesn't mean squat for driveability. Part throttle/low rpm tuning is what you need, and that takes some finess/experience, not just tweaking WOT timing and mixture on the dyno.
Even with your gears, a competent tuner can make that 228 cam very driveable. I have a 228 in mine, PCMforLess mail order tune handles all the driveability aspects just fine, we just tweaked the WOT mixture and timing on the dyno.

The surge is due to improper tuning, the cam stated is really not very big but the 110 lsa might be your dislike. Depending on what the Le2 heads flow, the runners might be too big for what you want. For early torque you want low duration, somewhere in the 218-228 range with a 112 lsa, this will have a slight lope but again this might hurt you depending on the heads stats. Don't recall your drive train set up but as stated if a M6 go with 373's or 342's with an A4, tho we usually do the 373 with an A4 and 410's with the M6. Some guys drive around with 456's and cam durations in the 24x range and call them DD.( like me) Others like something closer to stock drive-ability but with more power. I believe you are in between this.

Waiting for you PST and MST guys to wake up...
Wicked, Gregrob, Pat- I hear a lot of guys throwing the biggest rockers they can find on a 220s cam to get the .570-.585 lift range. What's the wisdom of doing that? Most will say it's in the name of increasing torque, but at what RPM range- 6100-6800? AI will advise against that much lift on their 190cc heads. They like 220s- low 230s and about .545-.550 due to the flow efficiency of the ports. Tell me if I'm approaching it wrong. The guy that did the heads on my main ride was wanting to do 1.6 intake and 1.5 exhaust on a 503 but I'd already bought a full set of 1.6 Comp UPMs. I could see adding a ton of lift to stock heads to compensate for poor port flow, but not on ported heads. School me...
