thinking about a new intake manifold
thinking about using a carb intake and converting it to EFI. What are the benefits to a carb intake converted to EFI?
also thinking about fabing my own sheetmetal intake. would just have to learn the math needed to do this.
if any one has any links for that im all for it.

my motor is not yet built but isnt nothing special. 450 at the wheels.
mainly just hate the looks of the stock intake. i really would like to do the sheet-metal intake for the learning experience and to practice my tig welding

Go take a look at this and take some notes. Hasnt been on a dyno or at least been posted up yet, but seems very interesting.

unless you are planning on throwing gobs of nitrous to your motor, i dont really see any benefit at the 450 range. im considering it on mine, but i plan on revving it to the moon with a good bit of dope. just my .02

1. Upper rpm (assuming you go with the Victor E)
2. Has more HP potential, ability to flow more air.
3. Opens up your nitrous kit choices IMMENSELY, and the kits themselves are cheaper. Basically just about any 4bbl carb nitrous kit can work.
Drawbacks:
1. Cost. The manifold (Victor E) is about 250-300ish, fuel rails are 75, and you will have to do some fab work to adapt your fuel lines to them. Plus you will need a custom elbow, to fit your throttle body, or you will have to run a 4bbl throttle body, along with a throttle position sensor. Don't forget you will have to convert the manifold to the LT1 head bolt pattern. You can purchase a custom elbow for 300ish from a vendor on here. Figure about a grand for everything you need.
2. low-end power will be worse than it will with the stock manifold.
3. Hood clearance MAY become an issue depending upon your elbow. Forget about running a tall nitrous plate though unless you are running a cowl induction hood, or something similar.
The only hand fabbed sheetmetal intakes that I have seen are for seriously large displacement motors. They look exoctic and cost a fortune, and usually aren't meant for cars that see any street action. Not needed at all at the hp levels you will be at. I really doubt that you will widdle away in your garage and come up with something that will make more power than a Victor EFI manifold, on a car thats around 400hp.

straight from Lloyd's site
"LT1 LE2 heads are capable of producing 370 RWHP with our small 218/224 custom cam and 410+ RWHP with our 232/240 custom cam."
and i will be talking to him about a custom cam and a full roller valvetrain.
also will be freshening up the bottom motor and going .030 over

have not a clue on the how restrictive it is. im mainly doing it as a project and looks. eventually i will be building the bottom end and hitting it with a 300 shot

To the OP.......if you goal is only 450rwhp N/A stick with a stock intake. Get it cut, ported, welded......etc and you will be fine. If your goal is 500+rwhp N/A and you plan on spinnning the motor to 7500-8000 rpms the single plane or sheet metal is the better choice.

If it had the LT1 bolt pattern and EFI bungs already in it, it would be worth about 450-500 bucks easy. People could either run a 4150 style TB or get a custom elbow and run the stock TB.

Actually Taner has a sheet metal intake.
