just looking for some cam ideas from you guys that have tried some different cam combo's

my set-up

bowtie block

moldex stroker crank

brodix pontiac heads, 2.1" titanium intake valves, 1.6" inconel exhaust

will be running on e-85/e-98

currently has a innovate 80mm r trim turbine wheel,
looking to upgrade to a PT8884 CEA if the 80 doesn't give me my goal of 1000 awhp

any input on cams would be appreciated, choosing the cam is the next step for my head build so i can choose the correct springs

you will need every single detail of the build to properly spec the cam.

truck weight
gearing
TC stall speed
header size and type
rpm range of the engine
turbo size
intercooler size and type
tire size and type
intended use if the vehicle
CR of the engine
block type
intended type of cam drive
solid or roller lifters
rocker ratio and type

there may also be a few more details that will be needed. this is just a short list of what I can remember from the 20 or so custom grinds I've had done over the years.

Ya, from time to time I get uber bored and I take a look around. I think I've got my fill for a few more months. I normally just check my Pm's and log off.

im not expecting to spec a whole cam on here just looking for a few tips and advise from people that might have been down that road before, and may have figured out a few tricks, or maybe figured out certain things that didnt work that well, things that may be thought of as norms in cam design.

that way when i do call to spec my cam i know to avoid certain things

thanks to anyone's input and advise

Re: cam spec recommendations

As Waller mentioned, there are many factors in designing a proper custom camshaft. My first attempt was spent with the Comp Cams master lobe catalog and a few weeks of research. It wasn't bad, but I quickly realized I did something wrong (very slow off the launch but very good power above 3500). I then spent some time with someone who really understands valve events and their impacts on the entire process. Then I had the second custom can ground. Way different power curve. Torque and power were strong all over.

A properly designed cam will make all the difference. Give us a call Wednesday and we can start.
