Would a Silverado crate engine fit into a Caprice classic station wagon

I have a 1994 Caprice classic station wagon with a
Silverado frame and chassis I am at the point in the
car's life it being 20 years old that I would like to
throw in a new engine and I am tempted to throw in
a Silverado engine for the towing capacity that and
I'm turning her into a rat rod no one can seem to
answer me when I ask them if a standard crate
Silverado 1994 engine would work for my car
anybody know lol
