360 w/J heads-need help deciding

It may be a decent deal, but without any documentation from the shop, i'd haul it right to my own trusted guy and have everything disassembled and checked for the proper measurements. Nothing worse then installing a engine, getting it all buttoned up and on the road, only to find the compression, bearing clearance, ring gap, valve springs, etc. isn't right.

Also, you need to understand that the .508/.509 purple cam is not the most street friendly cam.......meaning a 3,000ish stall converter and a gear of at least 3.55 would be minimum in my opinion for a mainly street driven car....Yes i know it's one of my least favorite cams, and others have made it work. Just something to think about in the overall picture.
