Not clear about foundry costs, but I think this printer is around $40K upfront, but can obviously be used over and over...

That prints in PLA and PEEK which are plastics.

Not suitable for things like intake manifolds and such...

"BigRep offers a specialized range of high-performance 3D printing filaments tailored for large-format, industrial applications. Key materials include heat-resistant HI-TEMP/HI-TEMP CF, engineering-grade PRO HT, flexible TPU 98A, soluble BVOH, and high-quality PLX/rPETG/rPLA, all designed for durability and precision.


Key Material Properties & Uses:

HI-TEMP: High-temperature resistant, rigid, and low-warp, suitable for industrial, high-heat applications (up to ~100°C+).
HI-TEMP CF: Carbon fiber-reinforced, offering high stiffness ( flexural modulus) an

Would you consider casting a special request for your last batch?

I like your efi crossram, but would like to use it with a set of "regular" FE heads, Edelbrocks or TFS. Would that be possible?

Coil packs?

Found it....

I have a SOHC piston...

If headers and sparkplugs are the only concerns, wouldn't welding in a flat plate on the inner side of the towers give sufficient clearance?

Ad states there is a lien on the car that would need to be paid off before title can be transferred. Doesn't say how much the lien is.....
