First things I would like to say about this cam and this particular set-up. I've been personally chasing something for a while now with these square port heads. I've been a cathedral port man for a long time and shunned these heads for the longest. I always saw torque curves that looked lazy, didn't look like they had any guts to them down low or even in the mid-range, and the only thing the graphs I'd seen had going for them were semi-decent peak power numbers.
After starting my job here at Tick, I started to warm up to the square port stuff, but I still wasn't convinced quite yet that you could achieve the same shape torque curve that the cathedral port heads are so seemingly capable of achieving with the drop of a hat. After doing my own testing, and a lot of soul searching I came out with the LS3 line of square port camshafts. I really hadn't had any takers on the Polluter cam, and to be honest I was afraid it was going to be a big fat flop with no guts down low or any torque to speak of. Well, as of today I am one happy man because I've done it! I finally was able to get the shape of the torque curve I've been after for so long with these heads. I'm very happy with the 400rwtq@3700rpm for sure.
This may all sound kind of stupid to some of you guys, but I really pride myself in the work I do on these camshafts of mine. I hope you guys and future LS3 Polluter cam owners can enjoy my work as much as I am myself.

I'm just waiting for someone to come to me with a forged LS3 bottom end that wants to stay stock cubic inches so I can show the LS community that these "Too large, too lazy, too big" square port heads can make great torque, produce an awesome power curve and hit 550rwhp H/C/I with stock cubic inches.
Your cam would actually work very well with square port heads.....

Hmmmm. Id have to switch to an LS3 intake/tb. Anyone ported the LS3 heads on an LS2? I have my eyes set on the 232cc ai heads but I could be swayed as long as price remains close and power could hit 500whp.

That said, we've also proven to make nearly 460rwhp/430rwtq with the Ai 232cc cathedral port heads and a smaller 227/235 110+3 camshaft that I posted a few weeks back.
Either way will net you your desired results Matt. To hit 500rwhp with either you'd need a better intake than the factory piece and more compression which may cause P to V issues with the square port heads due to their large intake valve.
Thanks Mike!

The dyno at New Era caught fire last year so it wasnt dynoed. Street tuned. New Era said it was a 535bhp. My rough estimate is 460rwhp on a mustang dyno. The power was fantastic 3500-6800rpm. Awesome street manners. Its going on the dyno in the summer...

That's the cam I been looking for! To have more torque at 3500RPM! I'll be purchasing the polluter cam for sure!
Thank you for all the time you spent perfecting a cam that has a better torque curve at lower RPM's, and excellent horsepower numbers!
