Die grinder, A must
you will need to take the casting texture off first. I use a wire wheel to knock it down and then a bunch of sanding. 400, 600, 1000, 1500, 2000 then coarse to fine compounds progressively on a buffing wheel in the Die grinder. It will take a long time. Once you have smoothed and polished everything, wash it with soap an water and get it clear powdercoated otherwise it will oxidize regularly. Especially with the temp cycling.

Go to http://www.eastwoodco.com they have too many things to buy for polishing [/url]

Are you polishing the outside for looks or the inside for flow?

does it really matter?

I believe it does. You would need a flex cable for inside, with smaller tools. Outside you want a mirror finish. Inside I would go for a matt finish. Shinier is not always better for flow.

I agree, it's going to take a die grinder. This is way too much for a Dremel tool.

True on the flex shaft. If the intake had a lot of detail you would even need it for the outside. Yeah I guess for intakes I use a hone anyway so it is different. Sorry Bart I an ornery cuss today

As far as tools goes, you can pick up a real inexpensive low duty cycle die grinder from an import tool company like harbor freight. you will need the arbor for the buffing wheels and at least two different rouge compounds to get your "bling" on Sophie.
