What's a good street cam for 243s w/yellow springs. Hey guys,
Well, probably like many of you have done before, I'm going back and forth on how to do my build. Lately its been finances that have been making me re-think my plans.
And because of that, I've started to think about just keeping my 243's with the yellow springs (good for .550) and just camming the car. Its going to be a street driven 66 Nova convertible. Obviously I need a nice lope to it to retain that muscle car sound, and even though I'm limited on choices, I'd like to focus on low-end torque than high RPM power.
I know that the best way is to get a better set of springs and get a custom cam made up, but that just starts to dig into the wallet a bit more (which I've already been doing). From what I've seen, springs can cost as much as the cam.
So, are there any thoughts on a nice "torque-minded" cam for yellow LS6 springs?
Thanks in advance.

63-LS-216/220 Comp Cams LS1 Camshaft - 216 / 220 .525 / .532 114 LSA 1300-6300 RPM Power Band. Computer Tuning Required with automatic transmission cars. This has proven to be a very well balanced camshaft in that it makes good power across the entire RPM range.
63-LS-218/224 Comp Cams LS1 Camshaft - 218 / 224 .527 / .534 114 LSA 1600-6500 RPM Power Band. Excellent mid-range torque with good top-end power. Computer Tuning Required.

If you are going to do a cam and get it tuned I would suggest going ahead and getting springs. I think that would open up more cam shaft possibilities. You can pick up a set of PAC 1218 springs for not to much and would still be able to use your stock retainers/springs.
If you don't want to spend the money on a custom cam, which I think is 375-400, you could get a used cam from the classifieds. A 224 is a proven cam and the 1218's would work with that.
Again this is just my .02
Good luck on whatever you decide and keep us updated.

the pac 1518 springs will allow you to run a very nice cam.look at some comp LSr cams,maybe 54-455-11 for alot of low rpm torque..tell us more about the ls motor you have.also consider a TSP cam pkg.

Given the specs, I would think it a hard cam to tune for emissions - but that is no concern for me. Carb'd bracket racing application in a 2700 lb car.

00 black ss - I am very curious to her more about this. I was going to use this for a carb application. I liked the C/L and yellow spring compatible lift.

I think you're right. I started this thread with limited research on single springs, so I was presuming I shouldn't even look at them. Just spent a few good hours looking around on here more. Seems as if I stay around .600 -.615 or so, I can just use the 1518 and be safe. $190 from SDPC isn't bad compared to my original pricing assumption of dual springs, retainers, etc.
Thanks for the replies everyone!!

Getting the springs for the cam, not the cam for the springs!

Pretty sure you shouldn't just throw whatever cam thats got the biggest duration you can find in just because it meets the lift requirements of his springs. It would be much smarter and much more enjoyable to get a cam that meets the powerband of the intended usage, the vehicle, and then go from there with what springs are needed.
The lobes on that cam must have a pretty slow ramp rate, the 110 LSA and such mild lift would be interesting....but I don't think optimal for that vehicle.

OEM springs shouldnt be used on anything but lazy OEM cams. OEM springs are not designed with performance in mind, aftermarket cams are. OEM springs are designed with low stresses and made to run 100K on a slow turd of a camshaft. Get matching springs for whatever you decide.
I would run a Comp 215/223 .604/.610 112 LSR cam(#54-455-11), or the 219/227 .607/.617 112 LSR cam (#54-456-11) with a set of matching 26918s. I run a version of the 219 cam myself with 918s. Nice all round cam, makes gobs of torque but yet pulls to 6000+
