I've read some spec sheets about the beefed up C5-R block (impressive)...but are there any external visual markings or unique identifiers specific to the C5-R block???

Thanks,

I am a proud owner of C5R and researched this same topic and found out that most C5R blocks will have a little white tag on the bottom of the driver side of the block that says "SCHWARZ ENGINERRING" and most also will have light color blue bolts on the bottom portion of the block. I have observed both of these items on my C5R motor with it installed in my car with my car up in the air on a lift.

Thanks for the info guys. I'm supprised there is no casting number that ID's the block as a C5-R . do you have to pull off the "SCHWARZ ENGINERRING" tag to do the install??? and when you say the block has light blue bolts are you referring to the 6 bolts mains???

Thanks

YEs, the 6 bolt mains are blue. No, you don't have to pull the tag off. It is part of your "pride," you know C5R block. The tag is only like 1x2 anyway. it is on the back bottom part of the block.
