Shot peening engine block question

[Justoldchevys]

The biggest problem I have found with the process seems to be time in the machine
It will cause problems with the broach and stamps but moreover that too moch of a good thing will alter lifter bores and put shot in every hole that is hard and time consuming to remove . I worked in aachine shop and we used hot tank
We had a. Freinf who used.ampro and I did not like the extra work it caused. Since it has been baked I would finish with a wire brush
Nothing worse than building your engine and then to find out the lifter. Bores areessed up
Good luck
