# fncychap package - reduce vertical gap/space between header and chapter heading

The package fncychap, using \chapter places the chapter heading 1/3 down the page. How can we place it closer to the top? That is; the words "Test Chapter" closer to the header "My Header" in the minimal working example (MWE) below?

\documentclass[twoside,a4paper,11pt,Final]{book}
\usepackage{fancyhdr}
\usepackage[Bjornstrup]{fncychap}

\begin{document}

\fancyhf{}
\pagestyle{fancy}

\fancyfoot[RE,RO]{Page Number: \thepage}

\let\cleardoublepage\clearpage

\chapter{Test Chapter}
\thispagestyle{fancy}
Some writing in the chapter.

\end{document}

Like the standard classes, fncychap puts a vertical space of 50pt before the chapter heading. This code redefines the two chapter head macros, you may adjust the argument of \vspace, I set it to 10 pt:

\makeatletter
\vspace*{10\p@}%
{\parindent \z@ \raggedright \normalfont
\ifnum \c@secnumdepth >\m@ne
\if@mainmatter%%%%% Fix for frontmatter, mainmatter, and backmatter 040920
\DOCH
\fi
\fi
\interlinepenalty\@M
\if@mainmatter%%%%% Fix for frontmatter, mainmatter, and backmatter 060424
\DOTI{#1}%
\else%
\DOTIS{#1}%
\fi
}}
% For the case \chapter*:
\vspace*{10\p@}%
{\parindent \z@ \raggedright
\normalfont
\interlinepenalty\@M
\DOTIS{#1}
\vskip 40\p@
}}
\makeatother


You could define a TeX length to store the value, then you would do better than the package which directly uses numerical values in its macros.
