Swapping engines

[Gilles]

When I installed a BBI small crank pulley on my '07 987CS, I used a Dremel to file down the TDC marker to make room for the smaller diameter pulley, and I was very surprised how soft the block material was, as the Dremel bit grinded way the material very quick and easy.

In other words, go slowly so you don't grind more than you intend it..

Found a better burr bit, one designed specifically for cutting aluminum without clogging. Also bought full-face protection, because grinding aluminum, unlike steel, creates flying shards that slice skin like little knives, according to a metal fabricator I know.
