I've been building & driving cars w/Must II front suspensions for more yrs than I like to think about. I also have used Jaguar(E-type)Camaro,Volare,Dodge Dakoda,Chevelle,Pete& Jakes...etc.

I think if they are set-up correctly ,have the proper spring rate & are aligned correctly the ride is close in all of them w/the exception of the jag which in a 32 Ford cabro had a slight advantage.......Fatman thru the yrs has not been a favorite of mine however, I have not used Fat man products lately.
As far as Nova/camaro subframe being too wide I have narrowed them a small amount w/success......Don.
