im having a hard time deciding what cam to run in my 07 Z. im hoping some of you will have some input. the car is a 2007 with 16k miles. so far, its got kooks long tubes, kooks off road x pipe and borla atak exhaust.
i am leaning towards a black widow r cam from carlos at vette air, but wanted second opinions.
when the cam goes in ill also be installing the following parts: (stock bottom)
prc 285cc heads milled to 68cc (.675 springs) Ti intake valves / stock exh valve)
fast 102 lsxr intake ported by peak speedshop
nick williams throttle body
callaway honker cai
morel 5290 link bar lifters
ati 10% super damper
katech c5r chain
catch can
arp hardware

my goal is to break 600 rwhp, but i dont want to sacrifice all the low end tq. the car might see 5,000 miles a year with an occasional road trip.

The BTR Stage 4 is what you want.. it always makes over 600whp with heads and a decent valvetrain.

The fastest Z's run this cam, like Jared who ran 9's n/a and 8.82 with nitrous.. Also, a guy in Canada (LS7bud) ran 9.81 with this cam and made 624whp, 555rwtq.

thanks man. i appreciate the input. I had looked at that cam but so many people have told me to staw away from a comp cam. a lot of people say that comp cams grinds can be off a good bit. any knowledge of this?

it's best to call Brian Tooley directly. No guess work involve.

Give us a call, we can definitely get you fixed up with a cam. We have done 100's of cams for the Z and will help you out. Also, we can use a Callies core for the camshaft so you never have to worry about the quality

I bet those guys at texas speed could really spec you a good cam, given that you are installing a set of their heads. You could have tsp grind you a clone of the btr stage 4, on their new lobes and on a callies core.

Brian may have a cam doctor to spin the cam and check the specs so dont worry about it being off the given specs.

By the way, you can even ask Brian to get you the stage 4 on a cam motion 8620 core.. but it will cost a little bit more do the quality difference.

thanks all. texas speed ill give you a call monday. couple other questions...is it worth it to install a katech oil pump since im going to be there already? ive got 50/50 responses from everyone else. also, is there anything else i should add that im forgetting? injectors, electric water pump, etc? the car does already have a 160 thermostat, ngk tr6 plugs, granatelli wires, and katech tensioner. its going to Vengeance wednesday to get tuned so i can have a baseline before the h/c/i install. ohh, one more...ive been told arp head bolts will be fine for my setup. do you all agree or should i go ahead and stud it? obviously there will be no boost until i have a new shortblock.
