Richard,
I believe Doug is right. It was a Roush 302 Ford. Money was no issue
with this project. 

I admire the Unsers, I met Jerry Unser several years ago when Ak Miller
brought him to a Roadrunner's Club meeting, this was when Ak was just
getting started in the Pike's Peak runs. I also met Bobby when he was at
the Salt. 

Some how, for me, though, the glory of entry into the 200 MPH Club is
tarnished  when membership is bought. It is just something I couldn't
do. There is a message for us, however, when it is sought by the likes
of Unser and Garlits, considering their fame, they still feel that
membership in the Club is an important acquisition.
