Hi:

Can anyone please provide the combustion chamber volume (cc's), valve
size and application for SBC head castings 3973370. They have a 1969
casting date - H 17 9.

Any help would be appreciated. They are not listed in the Chevrolet -
By the Numbers books.

Thanks.
Glenn Humphries

Just got through talking to a friend of mine. He informed me of a
sight called "mortec.com". I have not had a chance to go there as of yet,
I have been trying to locate my data (moving is a b___ch!). You can try
this sight, he informs me that there is all sorts of info available.
Good luck. If I can locate my S/B chevy data sheets, I'll post back
with what info that I have.
Later

Hi:

Thanks for the response. The casting number IS listed in mortec, but
they do not provide cc's. They state the casting is "over the counter."
This would lead me to believe it's a service replacement for some
condition that may have occured way-back-when?

I just bought a Nova with a 350 that has these heads.

Thanks.

I have went thru every box that I have, looking for my tech sheets. CAN'T
find a doggone thing. Sorry. Sooner or later I'll find my notebook and I will
be able to answer all of your questions.
