Aluminum Stage II Block 4.1 Liter - Very Rare |
Casting number NONE |
GM Performance made a few blocks (not sure of how many) and these WILL have a casting number on them. However, when the project was abandoned, GM sold the tooling to M&A Casting - Brighten Engineering in Colwater, MI. Aluminum blocks made by them do NOT have any casting numbers at all. These only have the raised power 6 logo. - Thomas Carter
