47-55.1 Camber angle

[mick53]

I am having the straight front axle on my 53 1/2 ton pickup altered along with 57 Bel Air 2" drop spindles so I can put my 12.88 Wilwood disk brakes on them. This is a driver that might end up on the strip if I am passing by at check in time. I have done some searching and some say negative and some say positive angle. I'm running EPAS electric power steering. I plan on running 8" wide tall tires. I believe the blown 292 weighs less than the 235 even with the 4-71 blower. I need an angle to give to my fabricator. Thank you for your time and advice.
