Leak Leak Leak....
With my 460 and manual steering in my 71, Its a PITA to try and cut the wheels...
Im running a stock sized steering wheel to make life easier.
I will say that back when it was small block powered, it really wasnt bad, even with 235 section width tires on it.
I understand that a manual rack and pinion system is easier than a manual recirculating ball system, but Im not sure.
Personally, as a driver, I prefer manual steering. The road feel is far superior to that of any power steering system.
Those that say it cant be done should say so quietly, so as not to disturb those who are doing it.
