been looking at fendwell outlet headers for chevy II's and i'm not seeing any like these. could these be a tri five header? they reach more to the outside then the chevy II headers i'm findind.
After reading and looking more i believe they are tri five headers, so i believe i answered my own question.
These are SBC Sandersons for measurements if that assists? In car installation These are SBC SWS for Nova and comparison https://www.southwestspeed.com/?sec=view_part&id=40180
mgtstumpy those are the same pictures i ran across as well. after seeing the prices i believe i'll do something different or build a set.
I built a pair for the 427 in my 62 II. It was fun, they work fine. And I was able to make them look like I wanted.
