I searched this board and did find someone who worked for a company that makes sheet metal EFI intakes (https://www.thirdgen.org/forums/tpi/...take-help.html), but near as I can tell from the pics he posted the runners are too short and probably too fat for a mild street engine. So my idea was to build a long runner sheet metal intake that is around 3/8" fatter ID since the factory undersized the runner diameter. And back it up with a custom plenum. What do you guys think are some things I need to consider for something like this? I'm still in the planning/sketch phase and actually begging the construction is a few years off while I gather knowledge, learn to TIG, and get the necessary tools. Thoughts or ideas?

 

The manifolds in those pics are made by Marcella Manifolds.

 

Yep. Marcella does great work, we have a good relationship with him.

We sell his products. Warning that these are $3000 and up.... But they are works of art.

As far as the runners are concerned, those are EXAMPLES of his work. He can make anything you want, if you're willing to pay for it.

Do not think that the pictures dictate everything he does. Contact me, if you want we can discuss what you want and I can help work with you on getting it.

Be warned, Jon likes to build these TO THE HEADS so you may want to send your heads to him.

This is all custom one off build to order intakes.

Here's the one I'm saving up for:

will you please stop posting that manifold ****...it's making me feel lowly
