Hey Guys and some gals...

I am doing an 853 kit and am sourcing some sps g grind cams. Is it the exhaust cams that make the hp improvement or the intakes that make the biggest difference?

Any help would be nice!

Thanks
Blake

I happen to have a set of the G grind cams which I don't think I'm going to use for my 853. I bought a set of big valve heads with them but I think I'm going stock cams or at least something milder since I'm just using this on the street and a couple track days a year.

PM if you are interested.

In any case, I'm curious what people have to say about this.

Speedzilla has some great info here.

996 sps cams are very different to g cams. sps go in without mods, g need deeper piston cut outs and give you a midrange hole.
