If you keep it at a 408 with a 4" stroke and 4.030" bore you will be a lot better off for durability that a 422

im looking at buyin a car that has this motor in it. never really heard of a 422 out of a lq9 block so kinda had me wondering

Oh it can and has been done, if they used the right parts it will last, just normally going slightly smaller holds up better in the long run.

I would be concerned with having that highly modified car as a reliable daily driver. I would also be concerned if I did not know the previous owner real well, and have a good history on the car.
