Need some Cam help
Normally i don't post much i am constantly searching for information, but can't seem to find the answers i am looking for. Well i pretty much decided on a 228 232 cam but am torn between a variant from eps or getting the 228 232 from cam motion on .612 lift 113+4 lsa. Was wondering if anyone ran this cam and can it be ran on 1518 PAC springs. I would really like a cam around this duration and similar lift only if it can be ran on beehives. Last question which lobes will be easier on the drive train and at what cost to power EPS lobes or Cam Motion

Ironically I have that cam sitting in my closet. The cam motion lobes are aggressive, I will say that. Here's my take on them when putting them up to a TR224 and comparing them: The base circle of the cam motion is smaller then the TR. So overall, it appears that the peak of the lobes on both cams are the same height, and curve very similar at the top, but the cam motion base circle is smaller, which actually makes it have more lift. Can you run the Cam Motion with beehives? I suppose, its under their lift capability. They would need to be set-up perfect, not just dropped in. I personally am going to run dual springs just for piece of mind. I chose the Lunati dual springs for 220 shipped from atlantic speed. Their isnt much info out there on these springs so Im gonna go for the guinea pig. Same with the cam, great review from one very trusted person was enough for me. In his words "I have installed literally 100 LS1 cams, and the Cam Motion was the hardest pulling cam only EVER" Thats all it took to sell me

They shouldn't require any flycutting, .612 lift seems like a lot for that 228 duration, I would think around .595 lift would be a lot easier on the valvetrain and not give up any noticable power. The 228/232 cam choice is good though, great balance of drivability/power/part life/and low end torque. Then you might be able to get away with the lightweight PAC -1218 springs (Which max out at 0.600 vs 0.650) and save $1100.00 over the PAC-1518s.

For any interested in Cam Motion. Here's one of the only vids I have found. This is a fairly big grind cam, and he does spray against the Viper I believe. All other runs are NA. He is a member on here. The music isn't mine so don't bitch at me about it

Well i got in touch with cam motion basically a quality dual spring is a must with this cam he said give or take 10 % 150 open 450 close, so i might look at some other cams that are similar but a little bit easier on the valve train. Really don't want to be changing springs out all the time i want to be able to get at least 30k miles out of a set of springs.

Well i really like the cam even if i had to get a quality dual spring like a prc eht or something similar. I am gonna try to get ahold of geoff from eps and see what he specs me out for my setup or find a cam close to what that cam motion cam is speced out to be. I just like the idea of beehives because if i wanted i could use all the steel hardware which does last longer, and its easier to rev the motor and you actually can make more power with beehives not much but its still something.

Just as an FYI, Im going to run the Lunati kit. $225 shipped to your door. It uses like a tool steel retainer to cut down on weight and price. Specs on the springs are as good as it gets and on par with more expensive springs like Patriot Golds and Comp 921s. It has a closed load of 153lbs and an open load of 400. Diameter and pressures are awfully similar to one of Comps more expensive springs. Even look the same too. Its not too bad shopping for duals.

That isn't a bad deal but i am gonna still check out eps and that cam is calling for a 450 open pressure by the way. The lobes seem really aggressive so i know the cam will make great power and the car is not my daily, but i want a little longevity with the valve train. You should hurry up and throw that cam in your car so i can see what kind of torque curve that thing will have.

Just so you know, Comp's 921 kit thats $550 has virtually the same specs. None of the dual LS1 springs I have seen have that much open pressure. Now, He said give or take 10%. Well, 10% of 450 is 45 so that makes I'm sure still conservative rating of 405 lbs needed. If you set the Lunatis at an open height of 1.150, you will have 400lbs. Now, I'm sure he was spec'ing springs for someone turning past the cam's peak. Which I will not. This cam peaks around 6300 I believe. I am only going to spin to 62-6300 then shift. I will not push this combo to ignorant rpms for a street driven car. I think anyone taking that same motto, and setting their dual springs up correctly will do fine. I mean honestly, who cares if you have to buy a new set of springs every 15k? At 1500 miles a year, I may not ever see the first spring change.

I can be an addict when it comes to driving these things just cruising around on the highway or find something to kill on the highway. My car is primarily a street car as well and those springs should be good for your intended use, i am just afraid of putting too many miles too quickly on the car. If i bought a spring like the EHT even though its more money it would last me longer, but i am gonna check out similar cams with slightly less aggressive lobes first but definitely as close to the same duration. But knowing me if i know i could get decent mileage out of this cam with good springs ill get it.
