I was looking on Scoggin-Dickey and a new 350 bare block is only $576.00. Does it require any additional machine work or is everything already done? Good, virgin 350's are getting hard to find around here. If it doesn't require additional machine work, it would be cheaper than prepping a used block. If I could order it through my local GM dealer, I could probably get free shipping also. My biggest concern is getting a block with Hecho en Mexico cast into the back. I like my truck made in USA.
