Default Cam only dyno numbers.

336hp / 355tq

I'll post the sheet later. It has an amazing tq curve. At 2000 rpm it goes straight to 330ft lbs, climbs to 355 and holds it almost the whole run.

Definitely shows why its so much fun to drive.

You obviously thought wrong. My **** is baby cam only and spray. No spray numbers today, couldn't get the bottle filled and clutch wouldn't hold it anyway. Will have spray numbers after I get a clutch.

I designed his cam. Specifically for his altitude. How much are you willing to pay us for the specs?

True it's a custom cam. I wanted to do a custom one from the beginning, tweaked for my altitude and setup etc. thehammer helped me do that.

We ended up using XFI lobes because they did exactly what we needed to do.

Rough specs are less than 220 intake, and .565 lift on both sides 111+a lot lsa

I took what I learned off this cam and thehammer again HELPED ME design z28camaro30ann's cam and it did 401 with le2 heads untuned and it has an awesome powerband too. Very fun to drive and will pick up even more tq when he's not super lean in the mid range / top as he is now.

I'm overall very impressed with how these XFI cams act. Seems like they get a bad rap because retards want to use the biggest one made and throw it in a stock longblock and when it doesn't perform like they want, everyone says the XFI cams are junk. With some custom tweaks and a GOOD VALVETRAIN the XFI lobes are great. I drive the car a lot, been using it for work lately and driving hundreds of miles a week and the valvetrain is rock solid. You just have to use good components.

Working on scanning the dyno sheet now

With STD correction factor (average 4% higher than SAE) I would have made the same hp and way more tq as the XE230/236 posted on here a few days ago.

Wouldn't you guys have a **** fit then.

about what you'd expect up top from a cam with -3 overlap @.050. any reason you retarded the exhaust so much besides emissions?

Well thats not what it is. Side effect of advancing it the way we needed to. Works awesome

I don't see how valve events can be described as a "side effect."
