Cam selection advice
I have read up and done a good bit of research on cams but I would just like to get some feedback on them from people who run them in their c5.
Here is the car build and my intended use and requirements.
99c5 A4 3200lbs with driver
4.10 rear
3600 circle D stall
TSP long tubes and 3' off road pipes. No mufflers
Fast 92 intake 90mm ls2 TB
Vararam. And a dyno tune.
Drs and skinnies up front.
The car is used 80% at the track as a bracket car. I occasionally drive the car to the track or go for a little cruise on the weekends down back roads where I can play. I plan on taking care of all the associated parts when doing the swap ie, ls2 timing chain, new oil pump, electric water pump, lifters, trays, pushrods, springs and trunion upgrade. I will also be adding a set of untouched 243 heads.
This motor has 2 race seasons and 150k miles on it so I don't want to spin a crazy amount of rpm. What cam would the knowledgable members of this forum suggest with my setup that would allow me to keep the shifts around 6200-6300 rpm. Range, work with my stall and keep this thing going till I have a forged motor built with a different set up. Any input is appreciated. I am sure when the time comes I will get with a vendor and have a custom grind done, just wanted to do a little off season brainstorming.

Several cams but how can you forget our own GM ASA cam, sole purpose of this cam to be use in track (not drag), to get quick in turns and sudden acceleration. ASA cam 226/236 .525/.525 110 LSA.
4.10 would be way too much for Auto, for manual it would have been just perfect.
I would not go more than 3.73 on Auto with Loose TC may be 3600 stall would be perfect match with ASA cam.

If you are planning on the best cam for your usage, it would probably be worth it to get a custom cam specced. Don't forget a LS6 intake setup for your new 243s, too. I would think something in the 230/236 @ 113 with around .570 lift, but I'm far from an expert on racing cams. I assume you'd still drive it on the street once in a while.
