Welcome to CHR..
It would be to your advantage to at least tell the club what motor your building this intake for... But then I have to ask, if you've got the motor??
How come you don't have the measurements???
the bolt holes are 3/8 inch for the head surface and 5/16 for the carb bolts-------sorry just being an ass--------why don't you use a gasket for the pattern that fits your heads?????
Most important, welcome to CHR and hoping that you enjoy a long run here.
There's got to be a story here! Why are you trying to scratch build an intake, and second, why would you be using sheet metal? A good, flow verified after market intake is not very expensive, and if you find what you need in the used market they're down right cheap. Can you share your story and explain a bit?
The only thing I was ever in on even remotely like this was we built some intake spacers out of aluminum, so that we could bolt a 340 six pack intake on a 440 engine; it worked great.
I have built a intake! Like all mentioned if this is a Chevy you might buy one, mine was for a early hemi and it took forever and a lot of machining, but a early hemi is a dry intake (at least after '55) and doesn't seal the valley making them MUCH easier than many later motors. Hey if your doing it just to try, have at it you can really hone some skills in building something like this (I call this hot rodding skills) if doing it to save money or for performance buying one is the way to go. Most of all have fun, otherwise it becomes more like work!
Here is the story. I myself have a 72 chevy 3/4 ton 462, with a 462 BB with around 600hp. My friend has a 68 Chevy Camaro drag car With a 555 BB WITH 1000hp. So anyways he's been looking at sheet metal intakes an the one he likes is 3200 bucks. There for I'm going to make him one an for me. I know there will be trial and error. So I know I will be making more than just 2.

For any other guys who don't recognize the term "Sheet Metal Intake", they're also called "Fabricated Intakes" in the parts books.... An example from a quick Google search, and yes, this is one of the expensive models, set up for EFI on a BBC -
Attachment 66009
And Hogan would be the preferred maker if I was gonna race one of them again-------I have I think 3 BBC tunnel rams tucked away somewhere out there on a shelf, but If I was gonna run efi I would go directly to Hogan or someone similar----but, that's if I was gonna race it--------it'll take aprox 12 hours of welding to put together the pieces-plus then all the surfacing, port matching, etc-then theres the water leaks, vacume leaks, oil leaks, fuel leaks-------I gotta go take a leak-----then to the ZOO with grandkids-------
