You're delusional. Beyond that, a full cnc manifold has a long list of issues that you haven't given any thought to.
First being weight. You're going to be 4x the weight of a good sheetmetal setup, and cost totally out of orbit as well. It may look pretty if you did it right, but you're not exactly going that direction either.
What is your internal plenum volume? Looks pretty small which is exactly what you don't want.
When you're forcing air into the motor the velocity stack effect isn't needed, and in this case will only disrupt airflow and eat plenum volume. See the small bells on the runners of the mitech manifold... yeah.
Have you given any thought to throttle tip-in characteristics/drivability with a single 4" throttle body?
The short transition from round to oval isn't providing any flow/velocity benefit and only making it a motherfucker to get the bolts in to attach it to the head.
Who exactly is going to tap a 2" dia (estimated) hole 1/4" deep to screw these stacks on? Good luck with that.
I don't see any O-ring channels anywhere, were you planning on doing all this and running some lame gaskets?
You need to make the sealing surfaces much larger to have any chance of it holding pressure. You're vastly underestimating the total force applied inside the manifold.
How are you attaching the fuel rails? Doesn't look like you'll even have clearance for the injectors. Did you put any thought into the angle of the injector into the port?
What heads is it cut for? stock, stryker, ported, etc?
I don't see any ports for pressure/vac signals?
What series AL? Were you going to cut already heat treated material, or cut it first then heat treat?
My $$ says you'll make less average HP than a good ported stock manifold, and have major sealing issues on the back of the manifold and/or throttle body mount. IF you can even get it bolted in place.
But it's a pretty picture.
