LS6+ streetsweeper HT "cam only" 440hp/409tq

I've got the SS-HT in my car with pretty much full bolt-ons. Car made 364hp/353tq with the crappy '99 853 heads.
The cam is getting swapped (along with the heads) this winter - this cam on a 111lsa is a little too gnarly to tune. Once it's warmed up it's fine but it needs pedal to stay running when cold and has some slight bucking between 50 and 60mph. Frost did the tune and he could probably get it better since he didn't get to spend as much time with it as we'd like.
I'm going with AFR heads and a mamo-spec'd cam (on a 114lsa this time) for more power and better driveability.

Keep in mind my car is a '99 which came with the crappy 853 heads. And it's an A4. And I'd never even heard of the brand of dyno (DYNOmite?) that we used out in Warrenton. Frost was there, we made two pulls, he tuned it in person, it's spot on. I really should have made it to the track the way it is, he even made a comment about it breaking 'em loose on the 1-2 shift, and that stalled autos with similar mods don't usually do that.

I just did some research on the DYNOmite dyno and I found an old thread here on it. Someone had this to say:
"My car made 367 hp on a dynojet and 323 on the Dynomite."

A little quick math using his numbers says I should be at around 414rwhp on a dynojet. So now I feel a little better!

ya I was gona say that but maybe he has shortie headers, and some other junk parts. My friends has a 02 35th ann (m6 10bolt) that put down 360/380 with bolts ons stock cam. Or the tune is bad, but I don't know frost to say anything about that. Its a 228/232 cam it should idle on its own, unless somthing else is up the tuner should have noticed, like a stuck or a autozone AIC the is not working right. I have a 24x cam with over .650 lift and it starts and idles fine. I know not every car is gona be the best perfect setup for the parts. But I wouldn't say the cam is issue on that car for what he said.

Yes, those mods do look good, I didn't your post at the end of page3 before? And alot of other info that changes thing alot form your 1st one, has already be posted I agree with. I'm not familiar with a dynomight. Have you ever taken that car to the track?
853 aren't that crappy of a LS1 head or anything bad. There 3-5whp of a 241, its just the surface smoothness, the ports are the same.

The streetsweeper HT is probably my favorite cam for stock cubes. When it comes time for me to build a motor i'll most likely be going with it but I'd rather have a 113-114 LSA
