Examples of the high peak power camshafts are the 230+ duration camshafts. The new TREX, the larger G5 cams, etc. Personally, for most applications I find the largest of the newest batch of cams to be a very silly choice. Very few people have their cars designed to take advantage of power in a very narrow range.
I think most people around here are missing the point that their cars are street cars, not race cars. Race cars tend to use high peak power designs that produce high amounts of HP within a limited range. In general, they are not fun to drive on the street, require steep gearing, and very good drivers.
People have been building fun, fast street cars for years. The method remains the same. Produce a lot of torque, keep the RPM below 6500, and make the curve as flat as possible across the board. With a lot of average power, it does not take an excellent driver to run good, consistent times. If you shift a little early, no big deal...the power is still there. Your parts last longer and it is a hell of a lot of fun to drive. I'm sure everyone has seen a car that runs everything from low 11s to mid-12s. No consistency, but the driver occasionally pulls off a really fast run. If everything is perfect, it runs like a rocket. If it isn't, it runs like a bolt-on car.
Most people around here have 3500#+ cars that spend 90% of their time on the street. We need to really consider that when we talk about camshaft selection.
Unfortunately, high peak numbers on the dyno sell camshafts.

I've just about decided on a TR224, I'm still doing research to make sure that's what I want. I'll be installing it with a set of heads (that's a whole nother set of research there 5.3 v/s LS6
) My car already has 4.10 gears, will that hurt or help with a 224 cam setup?? For me i am going with the Comp XER 220/561 @ 114.
Perfect combo for my Yank 3500 & my 323's. My car is also driven daily with 140K on the clock.
Stealthy, yet very good mid/high rpm's. Should get around 370 @ the wheels. Anyone run this set up?
Have done alot of research. I am an older guy.
Just want to hang with the Z06's for a little while....

How bad would a 228/228-588/588-112 with stage 1.5 heads be for A4/w3.23s for a daily driver. I want power but I don't want my power band to be at 7000 rpms either. My car has 40000 on it right now and I would like to keep the motor in it for as long as I can. I got a really go deal on the cam from a local guy so thats why I bought it. My car is 90/10 street/strip would this be a waste of time to put this cam in?

I wanted a 224/224-563/563-114 cam but someone made me a good deal on the 228/228 cam. Would this cam be too big for my setup? I have 1.5 heads with whats in my sig. I know this may sound like a stupid question but here goes. Would I need to change my Vig 3600 for a tighter smaller stall for a bigger cam so it wouldn't be so loose down low? My gas milage sucks now I could only imagine what it would be like after H/C install.

You shouldn't need to change your stall either. I wouldn't mind having a 3600 stall in my car..
Give up on the gas milage. It is gone as soon as you add the cam. Highway might still be decent but city will suck.
