Aluminum Intake finish

[crash]

So far I haven't seen anybody that is able to refinish or re-skin any of the Muncie aluminum castings back to OEM factory finish. The problem with these techniques is that the Muncie main case is of a different alloy than the rest of the castings, and when there refinished they all look the same, and they shouldn't. And they don't have the right shine to them
If you have ever had the chance to compare refinished castings to NOS castings you would see the difference immediately...
How I know this is I have a large selection of N.O.S. Muncie main cases, tail housings, mid-plates, and side covers to use for comparison. I also have a N.O.S. 1969 M-21 complete trans with the GM shipping box... Hope this helps...Crash
