I have a 340 on a stand with those manifolds and TTI head pipes. Although I do have the 90* adapter, I could roughly compare since everything is in plain sight. Let me know if you want a picture. :thumbsup:
Funny you ask im doing a T/A tribute so doing this exhaust which should be factory T/A challenger bend style since it uses the same manifolds to connect to A-Body T/A Exhaust System (1967-1974)-
