Thanks guys,i've come across a complete 88 T-bird 5.0 from a wreck with 28k miles for $250. It runs great,i just didn't know about the pistons and how much abuse they could handle. What's the compression with that dish with E7 heads? I've got a bunch of old stock mustang engine parts,STD HO pistons,cams,etc collecting dust and was just wantng to know what was the same or diffrent.Thanks for all the info again,Great site! keep it up!
