Holden cylinder head airflow specs?
Posted: Sat Mar 07, 2015 5:38 pm
This is mainly for Australian users but if anyone else has them please feel free to chime in.
I am looking for airflow specs on Holden (Australian GM) cylinder heads. I will gladly take specs of any (standard unported) cylinder heads but I am specifically looking for Red Blue and Black 6 cylinder and V8 both small valve and large valve (L34 sizes for V8). The reason I am looking for this is I have an old, but still pretty good, copy of Performance Trends Engine Analyzer and I want to work out various options for Holden engines using stock heads.
Yella Terra used to have this information on their website but most of it is gone now and I am not sure that what is left is reliable anyway.
Cheers.
