We are trying to get some available but it has been insanely hectic around here since Georgia's NMRA event last week. I will post them as soon as I get some. Sorry for the delay.

The video was just a teaser release. We are set to receive our first shipment of Detroit Rockers next week. Once received, we will install them on some shop cars and get some videos and dyno charts up. They will retail for less than $700. We are very booked in the shop and will probably install them after hours so we can get them available to you guys sooner. Once we get up some dyno charts, they will be available on the site.

If you do not plan on getting the blower for a while, it would be more beneficial for you to run the NA cams now, and with the blower instead of going straight to blower cams without a blower. The blower cams will offer 10-15 more power on a blower car than the NA cams (3-4 HP more) but will also loose more low end torque. We have a ton of customers running NA cams on blower cars and the gains are great. You will still see 30 hp gains with the NA cam on a blower car.
And this is with the stock springs/retainers without cam phasers limiters?
sounds impressive for a cam swap...
thats a nearly additional 100whp gain if I were to add an intercooler + these cams next year.

I think a couple key questions here in talking about this 30hp is, are we talking rwhp or to the crank? Are we talking about degreeing these cams for maximum efficiency? Or just drop in like most other NA setups?
As for the profile, can you tell us how many degrees are these cams are out of spec compared to factory? I mean most typical NA cams are roughly 2-8deg out of spec anyway. Which means they can still be dropped in, but physically degreeing them is always a best practice. Just very time consuming.
I'd be very interested in seeing a profile comparison chart with the Rockers, Thumprs, and Hot Rods.
