Your memory must be pretty short.

Mopar cam info, suggestions.

In that thread is a link to an interview with Billy Godbold, where he states he designed the XE lobes.

When the XE’s came out I was still running a lot of UD cams, and had spoken to Harold about the XE designs.
He didn’t care for them.

There is a quote in that thread from I think it’s the Chevelle forum, where he even says as much...... and that he didn’t design them.

And lastly..... again....... when the XE line came out...... UD was going strong.
He wasn’t going to be designing lobes for the competition(especially since there was still some ill will) while he was trying to grow his own company.

Billy G. designed the XE lobes..... Not Harold.
