Well, last one, and I’m not sure what it fits, it’s Red, marks have been removed, looks narrower than the O4B, and runners look taller than the 330-350-403 Performer I posted earlier....Center of plenum may have been trimmed down. Ports are good size, and un-ported..$75 Shipped to lower 48, local pick up in San Diego area or LA, with price adjustment....
Thanks,

$70????

 

that's the OLDSMOBILE small block OL4B by Edelbrock

 

Thank you for posting that. Is there any “demand” for these? Actually looks like it would “work better” than a regular Performer...

 

It's better than a regular Perfomer, not as good as the RPM. I know the BBO version won't clear HEI. I don't know about the SBO version.

 

SBO will not clear HEI either.

 

Sale Pending....
