the st1r is essentially a VS cam with 206* duration, we made 600 and are shooting for 700+
you dont need a "huge cam" to make the power you want, no need to sacrifice drivability
we have had the trans apart 6 or 7 times and have probably 7-10k in the transmissions if you want to count all the GMR Unobtainium stuff....
the engine is a bone stock 145k L67 thats just this side of stock for the most part.
