C.A.T. Fluiddamper?

Didnt know that....Catpep is still in Chino, Procomp is straight outta Compton. Speedmaster is in Rialto...? I think Catpep still makes alot of stuff that is rebranded with anyones logo. But they still have an AOL email address? Holy smoke signals Batman!

Take a peek at this thread from Speedtalk... it's about Speedmaster aluminum blocks but also talks about ProComp/Speedmaster parts. These guys are mostly engine builders and racers. They know of what they speak.
