Speedmaster intake porting. Hopefully I can make something out of this

It’s hard to tell from the pictures, but how does your burr finish compare to say...a 40 grit or 60 grit paper roll, or is it rougher than that?

Just to be clear, I don’t feel my unsanded finish is what guys like Meaux and Speier are referring to when they’re talking about “burr finish”.

I’d say it “feels” smoother than it looks.
But not as smooth as what they’re like after I’ve done the sanding.

PBR is making good time with that manifold.:thumbsup:
