Sheet Metal Intakes?

Sheet Metal Intakes?
Where do you get them and whats the ballpark cost? And how about some gains to expect? I hand ported my intake, but after doing some research I think I may step up to a sheet metal one down the road after more suspension mods.
The reason to start this thread is I read that the stock intake has about a 15% air flow loss, and a professionally ported intake will loose about 10%, and a sheet metal will loose only 2%-3% is that right?
Thanks in advance and please no flame wars

I thought the sheetmetal intakes were under $1200, but I guess I was way off LOL. Mabye I'll just send my intake to Lloyd and have him do a better job than I did.
But does anyone have some pics of ported intakes or sheetmetal intakes? I'd be interested in comparing them.
Thanks for the replies

I have a Hogan sheet metal intake on my NHRA LT1 Super Stock Formula Firebird. I doubt that the $3000 expense would be worth it unless you're flowing a large volume of air at high RPM. My car cas run in the 9.70 range when I really lean on it while NHRA Stock eliminator cars are capable of 10.30's with a stock manifold. In addition to the cost factor, there are complications with plumbing and clearance that must be addressed from the outset. For example, I probably put 20 hours into making the throttle body clear the fuel rails, plumbing the fuel system, etc. I use a motor plate so the engine sits a little lower in the car than a stocker. The manifold fit the block/heads precisely, therefore installation is very uncomplicated. Hogan required that I send him my heads and provide exact measurements of block height in order to make everything fit. The workmanship is very impressive.

Thanks for the replies, but I think a ported stocker will do just fine for a long time

Thought about that too, but don't really know whats involved. Any info would be appreciated

It depends on what heads you are planning on running as to whats involved. If you are running a SBC head that you are converting just tell them to leave the intake bolts in the SBC location and then all you have to do is drill for the injectors or buy one with them already installed.
Some places charge outrageous amounts to do the conversion, others are very reasonable. I think about 3-400 bucks is a fair price for the work. I have seen places that charge over a $1000 though and I don't understand why.
You can also now buy the Vic-JR or Vic-E from edelbrock with the injector bungs already done, so all that would be need is the bolt hole realigned which some people do themselves. Accel also makes fuel injection single planes.
1800 might be a fair price for a fully ported, with Elbow, TB, Fuel rails and injectors.
I bought a vic-e, ported, converted with rails for $300, but the TB and elbow can be that much by them selfs if you buy new.
