(Off topic) Holden cylinder head airflow specs?

Postby stormtrooper » Mon Feb 23, 2015 12:56 pm

Ok gentlemen I've looked all over the internet and cannot find good reliable airflow specs for pre EFI Holden cylinder heads. Some places have Intake but not exhaust, or they have maximum lift but nothing below, or they are for ported heads.
I have an old copy of Engine Analyser that I use, it is still a great program, and I need to put in airflow specs for a couple of engines I am sorting out.
So if anyone has stock Intake and Exhuast flow specs for Red 253, Red 308, L34, Blue 253, Blue 308, Black 308 (I think they are the same flow as Blue 308) I'd really appreciate it.

Cheers.

Hi Derek
Thanks for the link, it has ported and aftermarker heads but not stock standard.
Cheers.

Will keep looking

Might be a pain. My genuine 308 Holden manual doesnt even list flow specs

Thanks Derek.
I've joined a flowbench forum, I am going to build my own as funds allow, and I will ask the question there as well.
