Help me with cam selection
Help me with cam selection I have read the stinks and I have done lots of research. The car is a 2000 ss with 49,xxx miles on it. The car has, ati ud pulley, potz tb, slp lid, fast 78 manifold, Lt headers and Bassani true dual exhaust. The car put down 373hp and 372tq on the dyno, I will attach the graph. This is my weekend/ fun cruiser I ts not a dd. I want a cam that will be a good mid to higher rpm .I like to mess around on the streets a little and go to the track every once in a while. I would also like to try to autocross the car at some point. Also I was wondering, can I keep the cam sound down a little so the car does not get crazy attention without losing power? It can be louder than a sleeper cam so I can hear some of the money I wasted.

I'm not sure about head work to be honest. I guess there is sways a possibility. Also why do you think the dyno is generous? I put down 326 at slow hawk with no tune, potz tb and the slp lm2. Since then I add the ati ud, basssni true duals, fast 78 , long tubes and a tune.so that is about a 47 hp increase on a different dyno. I could see a few hp off but I can not see it being that far off.
373 rwhp is a little high for bolt ons only, but it really doesn't matter anyways since a particular number means very little. If it runs strong for what it is then that's all that matters

This spring when I bring it to the track will hopefully be good and I can get into the mid 12s no problem. I just question people when they say the numbers are high just because the stuff I have added. 47hp is not to bad for what I added. Long tubes I hope 20hp like everyone says, I went from a ls1 to a fast 78, the ud pulley, true duals and tune. Just alone the headers and fast78 should be 30 on the lower side. She could just be a dyno gueen. I see a lot of people run the 228 but my question whT can I do for a custom grind to quite it down a little or will I lose power ?

Now my question is, the 228r pick up around the same power as say the 227/232 Titan. What is the main difference? Will one pick up more power throughout the entire rpm range? I read the sticky but this is where I get a little confused.

Well the old 228 was on a little harsher lobe but has since been changed to a softer lobe. Cams around the 228/232 size have been around for ages, they are nothing new. Its a good compromise, decent low end, strong midrange, good top end. I thinks thats why cams around that area are so popular. I dont think youd see a ton of difference between the two, at least not enough to talk about. Im running an older version of the titan4 and my car has gone a best of 11.0 with a H/C LS1 and looking to go a little faster soon. I chose cam motion due to their good reputation, small business feel, they are semi local to me, they use the better cam cores and kip the owner runs cam lobes that help maintain valvetrain stability and quietness.
A larger cam on stock heads is really only going to make more power up top while sacrificing down low. With that said if the car has some steep gears, and a good stall if an auto, then a larger cam will shine more
That is a very good point, I would get pretty choppy. Now what if I save up and get a set of 243 and have them ported or get a used set that are ported? That would get me into the 420-430 hp area? Now are the heads a better investment then a rear end or worry about that when it goes?
If it's either/or, I think that the motor would run much better with a set of ported243. But the car would be faster with a better rear gear. So it really depends on which is more important to you
