I guess the OP should just buy a MS3 directly from TSP and cut out the middle man
That thread was some funny crap. I really wish I would have read it before I took my car to him in September for my cam install. I got lucky as the East Texas Goats were having a dyno day and I paid extra to have a wide band and tune done. It was a miracle the car had not blown up it was so lean. Tunning God my ***!
I just read some of that but had to quit, that's just ridiculous, sure it's the fact of the matter but it doesn't mean he does bad work, I don't want to start a flame war so I'm not going to say anything else lol
I have almost the same cam from TSP the Texas Giant Cam
Comp Cam Custom Comp XE-R 244/248
Intake Advertised duration 293 deg
Exhaust Advertised duration 297
Intake duration @50 is 244.
Exhaust duration @50 is 248
Valve lift Intake 612
Valve lift Exhaust 615
Its a real loopy cam I still need to take it and have a fine tune done... Right now im just doing the mail order tune and it dosent run well from about 800rpm to about 1500rpm

There were other people who came out later in the thread about their bad experiences also.

As soon as you get a good street and dyno tune you will be quite happy. I was never a fan of the Mail in.

What is your PTVC? Are these the old LS6 "style" with welded chambers? and what type and valve size?
A cam with those specs has to be on a much lower LSA, like 109-1 LSA, forget low end and anything below 4K rpm.

Damn, I don't understand how anyone drives around with cars that don't make any power below 4K RPMs. They must just hall *** everywhere. I don't think i have had my car above 4K RPMs in a few days. Its so loud, that i really have to be on a side road or something like that to avoid attracting attention.

Some poeple just want to have a barely idling, dragster crackling cam. It "seems" like the mother of all cams because it sounds mean.
Many cam designers, and myself will repeat this over and over.
It is not the size of the cam, it is the combo and how well it all works together.
On stock cubes and in street manners, any cam with over 15* overlap is counter productive in that environment.
How many times do we read " cam X did 4xx/4xx on the dyno", but how is that car running? Is it responsive (throttle response)? How wide is the powerband? How is low rpm trq (Acceleration)? How far does it carry (High rpm pull)? and so on...
Now tell me I made 4xx on a dyno and then I trapped 120+ mph, you have my attention.
Look back at this thread, such a big cam and barely breaking 400 rwhp, combo is not optimized, it will run like crap and only "feel" good in the last 1500>1800 rpms in your band. Why?
Well it is simple, the cam is too big for the combo at hand, that is it...

It is just the "market"

My info:
230/232 114 .592/.595
Afr 205 (62cc)
compression = 11.4:1
Here is the dyno sheet
You didn't help me with it, but is it similar to something you would have suggested? Any thing you would have advised against/changed? I am not about to change it(car feels great), but i would like to know how close my setup is to something that a professional cam designer would have recommended.
More info: heads have 62cc combustion chamber, running 11.4:1 compression. It is my DD, and I wanted a fun street/strip car with maximized NA performance, but also a small N2O shot.
Sorry for the hijack, but you can't post pics in PMs
Clearance is extremely close right at the minimum tolerances, it is the old style welded. The new heads and most other aftermarket would require flycutting.
By the way I tapped in at 119, not the 120 the other person mentioned but that is more driver error. My 6 speed gives me fits

You also stopped pulling before it even peaked, there is more to it with fine tuning. Good street/weekend warrior combo.

I figured it had to be the 6.0 heads.
