To polish,my method is as follows....get a 5 inch sanding disc "Bit" for your drill,a box of 120 grit stick on sanding discs (I get mine from lowes,about $7.00 or so for 25),and using constant motion,I smooth the aluminum.Once it's smooth everywhere,I start wet sanding with 220 grit,320,400,600,800,1000,1500 and 2000 grit.Once all that is done,Mother's Mag and Aluminum polish,then Mother's Billet Polish.Taaa-Daaaah !!!!! It really doesn't take that long,and the results can be great. This is my "do-it-yourself-at-home-with-no-special-tools" way of doing it.
When you're using the 1`20 discs,a small amount of effort and you can remove all of the casting lines and "texture" of the metal.I'm getting ready to go back over my upper intake and remove the casting line on the very front (thick mold line).
I did my steering pump bracket,tensioner,upper intake,throttlebody and spacer,and my hand fabbed intake plate.
The new engine will be all blue with the polished upper,and other parts I already mentioned that I polished.The valve covers are now different as well.I'm going with the smooth polished aluminum with my stickers on them I had made.
