sr20det Engine Block Number

[zoomswimmer]

What's up everybody?
Anyways to the point, I just got my sr20det black top swap today. I just want to make sure that it is the same one that they tested. They gave me a number for the engine block. I was wondering where could I find this number. Do I need to remove something to beable to see it or something?
Thanks

it's on the side of the block where the bellhousing bolts up to it.. It'd be on your driver side... Good thing I have an SR block sitting on my desk I use as a plant stand...
