Who uses these and how well do they perform compared to stock LS manifolds?

How is it for daily driven street use?

Thanks

I heard that church's dyna machine reads higher. Your not really gonna notice a different in driving wise. You should pick up about 5-8hp from it.

a IM will only really see gains if you have cams/headwork done to your motor

yeah true, but I seen a good healthy bone stock ls motor gain 6hp on dyno (tune). Blox is a replica of skunk2 and skunk 2 is a replica of a type r manifold. At least that's how i see it. Check out performer x manifold.

couple of the differences b/w blox and skunk2...

blox you can only bore out to a 65mm or so...skunk2 is around 70mm for a throttle body.

skunk2 just has a lot more R&D behind their manifold

Alot of people say "manifolds dont really get power gain unless you buy Tb".Wondering is that true

I use a Blox manifold, and from what I heard, Blox made Skunk2 manifolds and they just created their own IM products, without the Skunk2 branding on the log. True or not, who knows.

Mine is port matched at both intake and runner side, 68mm TB.

Set up is BC0022 cams, Crower retainers and dual springs, 68mm TB, RC310, ARC intake chamber with HKS filter, P8R head p&p and valve work, stock bottom end, mated with Maxim Works header JDM cat and 2.5 catback.

Dynoed at 167/130. I was told the IM give top end, but suffered a little bit of low end torque.
