Early LA 360 Blocks

K Will do thanks. Was interested in other than the obvious.
Block strength, cyl thickness, overbore capacity (CAN it go to 4.1 like a 340?) not so concerned about ability to go roller as am very happy with my solid flat cust grinds, and drop in rlr lifters have been avail for some time.
Would like updated info from those that actually HAVE and are running the early blocks, esp in 400+" apps.
Already have a few of them, so expense of obtaining isnt an issue.
Thanks
