Ron, 56 speedster, & James I humbly thank you for the compliments. Yes that is a breather box.
Here is yesterday's progress. Mostly tig welding alum, time consuming and a pain. Not much different from the last photo but the welds and the BOV location. I put it close to the engine comp grill so that everyone can hear the wooosh sound when it blows off pressure. Kind of like a snake hissing...... muhahaha... Next to start plumming the cooant system for the water exchange intercooler....
If any of you guys and gals out there in speedster land want a custom engine, or other parts for your speedsters to give them that extra little something, I am currently doing private work.
