A lot of the parts are similar though so using your head you can apply some of techniques.
By no means did I mean to mislead anyone about what the book covers. It certainly does not cover any pre 1963 engines. What I meant by the above statement is that you can use some of the techniques on some parts that are
similar in
design (but not necessarily the same). For example the airflow into and out of the engine is similar. The same problems with siamese ports exist, using my imagination I can apply the techniques in the book to a 235 head. Same goes for removal installation of cam and crank gears, compression ratios, offset crank grinds, cam timing etc. I haven't done it yet but I bet if I called some of the listed 292 cam manufactures listed they either have or can easily make a performance cam for the 235. Without the book I wouldn't have known where to start (besides here at the 'bolt of course!).
Info on performance tips for the 235 are hard to find, the book and my imagination can get me part way there. The rest I can hopefully glean from you fine folks here at the 'bolt and my friendly machine shop.
Hope that clarifies.
