What is the casting number? The B/E body manifolds were always vaneless...sounds like you may have B or E body items?

Never seen a C body 70/ 71 TNT/Magnum/ Super Commando drivers side manifold without vanes...unless they were ground off?

Most websites don't even mention the C body HP manifolds like the 409s above...just "C body"...which is normally the logs.

I will have to see if I have photos of them or wrote the numbers down as the car is not accessible at the moment.
