vinci cams
Im about to order the "XXX" cam from them in the next couple of weeks and ill try to let you know some numbers. I decided on them because of some cars that i have seen run the cams. They are very well known for cams that produce awesome power under the curve, in other words the TQ numbers are very parallel and linear to the HP numbers. Dont be fooled by the relatively small profiles they offer, they are healthy cams that give big cam cars hell (t-rex, Magic sticks, etc..)especially stock headed cars. I have spoken with them and discussed alot tech and i just happen to agree with their theories. Big cams are nice and do great with big flowing heads, make big dyno numbers and etc...but arent always practical for daily drivers and lots of street use. Its just my OPINION and by all means its your car, but i like to have power right when i mash the pedal not have to tip in it and wait till higher RPMs to pull. Good luck on your decision, and dont let big dyno numbers let you pick your cam. 
what about some of their bigger cams...228/231 .600/.600 i think is the biggest the vinci tuner will tune...how much would i expect with full boltons with that cam and tuned with their tuner?

Probably best to call and discuss this cam with Roger.
I am happy with my smaller cam, it runs well and car is very drivable which was important to me because I didn't want something the wife wouldn't drive. Power is good down low and 6th gear highway cruising is excellent delivering over 30 mpg. I also didn't want the car to lope too much, because I feel the C5 Corvette is more of a refine sports car as opposed to a 60's muscle car, but that is just me. I am happy with my choice, and am now moving on to heads. Again, I took a different path then the most popular and went with the Dart 205 heads. I wanted to small ports and the flow numbers looked good for the out of box price. I don't want to stray too far off topic, but the point I am trying to make is each component I have selected has been to work well with the ones already on the car. The only difference will be when I put on the Darts, I will move from 1.8 rockers to 1.7 rockers due to the over the nose spring feedback forces to the lifters and I don't want to run the springs that came with the Dart heads too close to the acceptable lift limit.

Yeah, the Crane/Vinci under the curve power speeks for itself. I incorporated some of their VE's into my custom Vette cam and it is working real well.
So far with no other mod beside tuning with the Vinci handheld, my 210/224 cam put out 27 rwhp and 32 rwtq over the stock cam.
All else is stock (even the air filter).
I will do a write up as soon as the whole project is finished.

What am I missing? Comparing the Vinci lobes to Comp XE for a given duration at .05:
Advertised duration is shorter for the Comp XE
Comp XE's duration at .200 is equal or greater than the vinci.
It seems like the comp XE lobes are more aggresive.
I'm not sure how to compare the the TDC tappet lifts, so I don't know if there is an advantage to one lobe or the other.
Like predator Z said, I like some Vinci's ideas about short duration tight LSA cams, I just thought they were using very fast ramps.

I don't think they are using very fast ramps, at least not according to my calcs. The cams are also compatible with their accererated lifters. But, the cams (at least mine) is quiet and hopefully not too hard on the valve train.

here's some reading about the accelerated lift technology to help you out. http://www.vincihighperformance.com/...RTSPARENT.HTML

I've tried to find out how many degrees is typical between .004 and .006 since I've seen other cams rated at .004. I've assumed its only a few degrees but haven't stumbled upon anything quantative.
I am confused on this as well. I have been reading David Vizards book, and he states the standard is to measure 0.004 at the tappet but that some cam manufacturers quote 0.006 at the valve. For a small block Chevy, which I think was the source of the standard, with a 1.5 rocker the two would actually be the same.
Am I missing something?

take two likewise modded ls1 cars both with the same size converter and the car with a bigger cam is gonna eat up the vinnci.
if you want great power threwout the powerband, the 224/224 cam generally cant be beat.
