5.0 HO engine specs?
I need to know the compression ratio of the 1986 5.0 HO. I thought these were dished engines but I recently replaced the head gaskets on my stang and found that my engine had flat tops. Is this stock?

Re: 5.0 HO engine specs?
I think its 9.3, or something close. Yes, they come stock with flat tops...

Re: 5.0 HO engine specs?
+1.
Chamber and deck height variations altered it up or down slightly depending on the tolerance stack up. Yes, the flat top pistons are stock or stock replacement and should be forged. They will limit your cam choices, though.
