Ow it will run just take a bit of tuning to get it right. They will outflow my ported LS7 heads and since they are my bottleneck should let the LS7 shine to its full glory hahaha. Since I am speed density anyway shouldnt be too hard and throttle response should be fantastic!!! I found them while doing a search for itbs and they also make a billet lower manifold to match to the LS7 heads just waiting on that to get here already got the ITBs they look great I am having the tops and other red pieces painted to match the car hugger orange. Cant wait to get it all sorted out!
The whole setup I will say cost me less than a beck or wilson if that helps any and each one can outflow the heads so there ya go

Depending on the drivetrane that Firebird has it could be considered low.
A Cammed, Ported Head, Ported Intake, all NA, through my knowledge says an LS7 should be around 700-750 at the crank with no Accesories running it down.
At the wheel I would have expected around 580-600 for a mild mannered LS7.
It may have stockish heads and intake which could bring the numbers down, and no one here has seen the tune so its up in the air.
But that is still a nice build none the less.

It is far easier to mess a ls7 head up by porting it than to help it. Make power that is. It is pretty easy to up the flow numbers, but actually make more power is another thing. For 95%+++ of street car builds, the factory ls7 intake port is more than enough. Typical port jobs done to these heads, combined with the typical big cam applied to them, make less power then if the heads would have been left alone.
I am just speaking in general, not talking about any body in particular, just some of the results I have seen from "ported" ls7 heads around here..

That's fantastic! I work in GC at the hospital but live in Wichita. I recently finished my 69 SS/RS Camaro vert with a LME modified LS7. Those are the numbers I was hoping to see from that powerplant. Just getting out on the pavement for some rubber time after 18 mos. I'm in GC until Thurs. I'll stop by to check that ride out, very cool.

Hey JG thanks for the call, got tied up Weds and couldn't drop by and heading back home today. Pick up the Camaro tomorrow from my builder. Had issues with the acc. drive, fixed now so I'm putting some pavement time in next week. I'll post you some pics. Scott wanted me to give you grief but you sounded like a straight up guy so I told him to F o, lol. Cool ride nice #'s. Hey Bandit, Kinsler?
