Meh....I wouldn't be thrilled with a 511 block. That's an early 4 bolt main 400 block, and the later blocks (509s and 817s) are more desirable, as they have more metal in the main webbing area. I would be hesitant to use a 511 block as anything more than a street cruiser / occasional weekend trip to the track deal.
