Larry Ragland ran a one in his Arnold truck for years, Robby gordon has one in his old one as well. They are very strong, get one.
That guy is no joke. Yesterday I watched him take a box full of loose parts and build a complete set of headers in less than 8 hours.That ford truck is owned and built by Greg Holman of R.E.F. Or other wise know as the exhaust guy. He builds the exhausts on just about all the trophy trucks out there. And some buggies too.
I ran into Andy Casale a couple of years ago, He at the time, was the owner
of Casale. Casale has been making marine V drives for forever.He described he
had done some development work on some of the well known trophy truck & truggys
(possibly Herbst)?... Anyway, I am sure he did some work developing gear boxes
for stadium superlites & other off-road race cars A few years back.
