i know im gonna open a whole world of crap for this but what would be better for a cam in my car new ported aluminum heads ported intake longtubes 1.6 rr's and a 2800 stall with 3.23;s gears the cc306 or the cc503 mostly a weekend car with street use and strip

 

you could get away with either, depends how radical you want it. id personally suggest the 503, since u have a rather small stall. u might want to upgrade to a 3500 or so, do the 306 and some 3.73s then youd be flying

 

i may go with a bigger gear butt i may go diff rearend before hand as the 10 bolt blows i also have 1 free stall adjustment if i need it also.....i know the lope dont matter but i kinda want one and i like the 306 whats the 503 sound like any clips or anything...if there is im all over it like a bum on a bologna sanwich

 

I have the 503 and it has a very nice idle. Going to a bigger cam isn't always the best idea. You may get a little more peak power by using the 306, but you will need to rev the engine very high to ever see it. I would put a lot of thought into how you will be driving the car and what you want out of it before selecting a cam.

 

Thats a very good post. I originally started out with a large cam and am now down to a cam that has 20 degrees less total duration than my first cam. I thought peak numbers matter and so I went bigger, but never liked to rev my car high enough to make the power. I know have a smaller custom cam that kicks hard in the low-midrange right where I drive. Lately it looks like it would be hard not to go with an LE1 cam. People have been putting down 380-400rwhp and they don't have to rev real high to do it either.

 

how is the 503 on spray im gonna do a 150 shot prolly or 200 not sure yetsee what the motor likes

 

503 works very good with spray, im running 10's with a 383 and 503 cam and 150 shot

 

unless you are willing to spin the cc306 up to 6500+ and have headers you will be wasting your time with it. and when you start spinning that high you have to worry about your rotating assembly.

 

Like Critter said, you need to REV the CC306 to get the power. The CC503 is a much better choice.

cool dont wanna spool it up to 6500 all the time what stall should that be at with the 503

 

you know, the cc503 and CC306 aren't the only cams out there.... just the most talked about. Sounds like your looking for a mild cam there are allot of variations out there that you should search around and look at first.

 

i know not the only cams out there but they have worked the best for me in the past had 2 lunati blow lobes off and 1 crane snap i just like the power ranges of both and witch one will like the spray better.....oh yeah and i like the lope of the 306 i know lope dont mean anything and if that was all it was about id do a hotcam but id like suttin up top with a lope
