Default TSP Giant Cam

Anyone making over 500 rwhp with the TSP Giant cam in their set-up?
Any sound-bytes/idle videos of this cam?
Ideas, concerns and comments are always welcome about this cam.
Thanks.

Thanks! The car is a heavy pig and I still haven't gotten it to hook very well yet (best 60 is 1.75), but on motor it's run 11.6 at 120mph in 3000ft DA. Better weather and a decent 60ft should get low 11's n/a, then deep into the 10's on the jug. Idle speed is 1k rpm.

^^^I believe that the MS4 is a huge cam for anything less than 400 CID. (this belief comes from lots of years experience building first gen SBCs) Something with that much duration tends to be really peaky in a small CID engine. Currently, I am building two of my "first" LS based engines...still learning how these engines perform and what mods they like/don't like and when and where they like to live and breathe right at. All of your help and input is greatly appreciated.


I purchased the TSP Giant for a good price, to put in a 408 CID, iron block, LS1.
