GPI SS4 no fly cut vs TSP stage 4 "f35" cam???
I'm looking to upgrade from a stock cam to one of the ones listed in the title. I'm leaning towards the GPI cam but just found out about the TSP cam. I do drag race just for fun and drive the car somewhat as a daily. Power wise how do they compare? I know the GPI cam has seen 10s in the 1/4 on an otherwise stock car has any run the f35 cam and got a time slip?
LS3, I am already full bolt ons. Sent from my Pixel using Tapatalk

They are both pretty good sticks. The SS4 NFC is definitely a little bigger stick, and truly represents the very edge of a max effort cam (with respect to PTVC) you can stab into an LS3 without pulling the heads. GPI has a really nice cam lobe that does a good job of being aggressive without totally thrashing the valve-train. Not a shot at TSP, but I don't know if anybody has done more studying and tweaking of LS3 cam timing (within the realm of stock PTVC max effort) than Ryan Stevens. That combination of expertise and truly top notch service gets my nod every time.
I'm not sure that any of these guys running 10s with their NA stock bottom end cars can really be considered "stock". They all have significant weight reduction, dedicated drag wheel/tire setups, big converters, and some have gone as far as to swap to the TH400 to get these cars that fast on the kind of power a stock bottom end car can make. It's exceedingly rare to see it with stick cars, although a few have done it. That's not to take anything away from them, it's a BIG accomplishment. It's just to say that you can't just stab one of these cams in and expect to run 10s, there are a lot of other complimentary things to consider to get into those numbers on a NA SBE setup.

Power wise is what I meant by saying they are stock. I have a dedicated drag setup (bias ply) and have shed some weight. So hoping to get into the low 11s maybe 10s with whatever cam I go with. Sent from my Pixel using Tapatalk

I'm trying to find the time to move to the SS4 NFC, will try to do it before CamaroFest. Would be an interesting comparison.
