Another 76 Brazilian Hardtop

Last october's weekend we took it to have its powertrain reinstalled, and on decembers first weekend, it was back at my parents house.

And it has basically been sitting since.
I'm working on the parts, cleaning, painting, polishing, buyng some others...

Last november we removed the engine, it failed one year after reinstalation.
Eaten camshaft, lifters contact face were rounded, rings on four pistons were cracked (pretty bad scratches on the walls), eaten main bearings...too many defects to even start wondering where everything started failing.
Now I'm studying about camshafts, pistons, heads...can't go too far, but would really like to improve its "breathing" a litlle.
