Larry,
For what it's worth, I bought a set of the Sanderson long tube big block
headers. Had a clearance problem on the passenger side of all places. It
wasn't touching, but far too close to the lower a-arm frame mount. So
close that at idle or under torque it would have rubbed the frame. That
and the ground clearance was a concern since my Chevelle is lowered. They
just hung a little lower than I was comfortable with.
I called Sanderson and they were very helpful and said I could send them
back for replacement. To improve ground clearance, I am going to exchange
them for the intermediates. I think they will charge me a "restocking
fee", but at this point I'm not worried about it. I haven't sent them back
yet, but if you're curious how it all works out, I can let you know.
