Got a small block chevy engine and was wondering if any chevy guys could help. It has a brass tag riveted to the front of the block that reads CLV-1 24832. Any ideas on what that is?? Also has dipstick places on both sides. Numbers on the block are: VO411CHH (not sure if its a O or a zero) , and 3970010, and B208. Any info would be very helpful, or any info on places on the internet that might help would be appreciated. Thanks in advance.
