Regarding Caml (that I think falls in your category of lambda-calculi
language), you'll find a research report describing the implementation
of Caml in Caml (be aware, it is quite hard to read) :

Xavier Leroy. The zinc experiment: an economical implementation of the
 ML language. Technical report 117, INRIA, 1990.A
 http://pauillac.inria.fr/~xleroy/publi/ZINC.ps.gz

Otherwise, look at papers of team Contraintes, Cristal, Moscova (and
others I've not in memory right now) at INRIA. They use OCaml for
various languages, type-system and compilers.

In Ocaml, except for the Garbage Collector and the bytecode runtime
environment, both written in C. The OCaml Language is unable to express
some low-level systems.

But you could have found it by yourself looking at online source code:
