BTR VS Tick Performance Cam
They both have great customer support, I've just been in contact with tick more. Mainly because that's where I just ordered all of the transmission parts from. But yeah martin suggested the SNS stage 3 so I guess I will go with whoever has the cam motion core. Now all I need to worry about is the head gasket thickness I should go with!
You're looking at essentially what I have... I have a Cam Motion ground EPS Cam using EPS lobes (which are softer than the LSL in those cams, but don't give up anything in terms of power).
I have a Btr4 cam and love it. Good low end torque and top end pull. Thats threw a 3600 fti stall auto with 3.73 gears. Have not had it back to the track with new cam. Hoping for low 11s.
The deciding factor will be how much more an 8620 cam motion core will be between the 2 companies. The customer service has been great from both vendors.
So just to clarify, the BTR 4 will have a tad bit more low end than the SNS 3 because it has less overlap? I'm not sure what the overlap is on either cam I just know that if the LSA goes down then overlap will increase vs the same cam with a higher LSA and less overlap. And I do understand at the end of the day LSA is just a sum of numbers

Both cams will drive the exact same, literally. You're splitting hairs trying to find a discernable difference between the two. Run the numbers into a camshaft overlap calculator, I'm pretty sure last time I did they were both around 16 degrees overlap. Lsa plays a role in overlap, but its not the only factor. You can't just look at one cam with a 111 lsa and say it will have more overlap than a 113 lsa. Generally speaking that trend is true for given durations, but there are other factors that play into it.

I tried both:
1. 2006 Corvette A6 C6 LS2 - The heads, cam and fast intake all from Brian Tooley (Stage 4 cam, port matched intake, 220cc trick flows) and it dynoed 502whp SAE through a stalled C6. Converter was a Circle D 2E
2. 2002 Fbody Camaro Z28 A4 LS2 - PRC 227 Heads, Tick SNS Stage 3 Camshaft, unported fast 102mm. It dynoed 489whp SAE. Converter was a Circle D 4c.
Both cars had 1 7/8 headers... Both LS2.. Both converters locked.. but obviously the induction system differs from an fbody to a corvette. Judging by the number, they should perform almost the same, the BTR dynoed higher because of the ported 102mm and maybe the drivetrain. Pick anyone of these cams, both Brian and Martin are great support.

Maybe the heads make a little difference.. I'll see if i can post some pics of Tooleys tfs 220 next to prc 227 side by side. The heads looked similar in valve size and ports/runners.
I have a comp ground SNS Stage 3 and I was pretty pleased with the performance. It's actually a custom grind but based off of the SNS but the lift and lobes are changed to work better with my rockers. I think either cam will be a good choice. And I would just cut valve reliefs in the pistons and run the smaller head gasket to bump the compression.
Without fly cutting the new Pistons, I'm guessing neither cam will clear with a .040" gasket. Which a clean up cut on the heads and the thinner gasket is the best way to get elevenish compression but then the BTR stage 2 on the 8620 CM core would be the best balance of all the compromises.
I like my BTR Stage III...the Stage IV wouldn't fit with heads cut .015 so I went with the III 
The power was still climbing fast at 6700rpm (I asked tuner not to spin it past that on my SBE)
The power was still climbing fast at 6700rpm (I asked tuner not to spin it past that on my SBE) Thanks guys for all of your responses! Love to hear everyone's opinion and experiences. I think I will just be running a 051 head gasket though and not worry about PTV issues.
All of our shelf cams lobe profiles have been redesigned by myself and they are all 53-55* major intensity and we don't push the .200" number. I have tried everything from fast to slow, and 9/10 with the kind of parts most LS engines are using the slower smoother lobe profiles make more power.
Comp had a snafu at the beginning of the year regarding supply and demand of cores due to a change in their system they implemented to help stocking and ordering. They pretty much ran out of cores. We were experiencing wait times of 2-3 weeks and up to 1 month on most of the cams we were selling and up to 2 months on some of them, it depended on the specs and what they had available. That is just not acceptable when you sell as many cams as we do.
So we turned to Kip and haven't looked back since. I am very happy with the product we receive from Kip and don't see any reason why we would switch back. The fact that every cam is polished, cam doctored to within tenths of a degree and the huge selection of 8620 cores is something Comp just can't compete with.
