Lower LSA is the way to go. Patrick G helped me out with my cam awhile back, and it has been very streetable. Here's a link to my dyno sheet. If you have any questions about my setup I'll tell you anything you want to know. I daily drive, go on road trips, etc. The idle is killer, and it screams. I shift conservatively around 6400.

), but all in all, it's an awesome DD cam. I believe the key is in the tune....we had problems at first, but took our time and ironed them all out.

wow, that cam setup looks incredible.....your torque hardly changes!!!
That is similar to a MS3 but 110 LSA, 108 ICL, notice though that it carries way further than 6300, that is a mid/big cam
If you want something witha flat trq curve like that here is one:
230/230 .612/.592 111+2 LSA
2200>6600 rpm, peak 6200 with LS6 intake, shift 6500/6600,
If you like I can give you the specs, one of the best medium "all around" cams.
Another is TSP 228R, which they cut on 112+2LSA, but I like it better on a 111+3 LSA

You have it right up to here
Cannot be further fro the truth. Cam specs are not only .050 picture. You have to take into consideration lobes, other lifts, ICL and all the VEs to properly visualise what the cam can do. When you design a cam, you first have to decide on a power range to tailor your VEs.
TR230/224 is a good street cam for poeple not wanting to rev to the moon, 6300 rpm shifts. It has great VEs for cam only applications on stock headed motors.

I DD the TR230 and there are zero sacrifices. It has plenty of part throttle and low end grunt. Granted, I also run a PT4400 with 3.23's, so some may see my opinion of sacrifice as slightly skewed ( ), but all in all, it's an awesome DD cam. I believe the key is in the tune....we had problems at first, but took our time and ironed them all out.

How would this cam do with PRC 2.5 5.3L heads?

Predator can you make a suggestion on a cam that idles nasty, but has good off idle part throttle accel and broad power? I have been looking at the TSP 228, I will be using it with 243 heads, and I want to bump the compression to 11.0-11.5 since the 243's have quench pads. I am more concerned with overall power than peaky power, DD car that will see a little track time but not much so it also needs to be fuel efficient. A4 car. The valvetrain is AFR dual springs, TI retainers, HS rollers, Z06 lightweight valves.
And dosen't advance ground in lower the DCR?
OP sorry if I am hijacking but figured this is along the lines of your question.

To the original poster I was also debating going with the tr230/224.......I wanted a good streeable car with great midrange for my bolt on stock 241 heads car, but after talking to Pat G for a bit I settled for this custom grind- 232/232 .612"/.604" 110LSA +2 xfi/xfi
here is my thread with all the research I did...the cam should be here by thursday

3036r is a 230 lobe XFI exhaust
The way they will come out depends on how well the grinder calibrated his machine on that day. Not only calibration affects the duration, but lifts and LSA/ICL as well.
You can check the lobes on Comp Cam Master Lobe Catalogue.
In any case, that is a good grind, I use mine with XE-R exhaust.You'll be happy

Yes, that is one thing I really like about TR. They issue a full lifts report with every cam. Helps a lot with degreing.
You are going to be very pleased with that cam.
