You have an 1989 Beretta wiith a 2.8L It has a cracked block you found a block out of 1986 Fiero with a 2.8L Are these blocks interchangeable?
Hi guys. Mechanic here. Yes, it will work.
OTOH you are a bad person if you do it. Instead, you should fix
the Fiero. If you fix the Fiero, the gods will bless you. If you
cannibalize the Fiero to revive a Beretta, you will face eternal
If you want to, you could always put the 2.8 in the Beretta to
get a basic car going right away and then get a small-block
conversion for the Fiero. That would not upset the car gods so
== == ask a mechanic.
