and

*327/275 @ 299 horse power factor[runs with a Q-jet]

I "think" it will run in truck class "B" which is 10.5 pounds per factored horse power less (250 pounds allowed for automatic trans] plus 170 for driver

So, is this correct, using the 293 factor as an example

293 x 10.5 = 3077 less -250 class allowance = 2827 + 170 driver = 2997 race ready with driver. I am correct?
The 250 lbs is only used for adding or substracting on the shipping weight so you can move up or down in a class. Looking at your shipping weight and using the 250 lb rule, your truck fits A or B . At B race weight if your motor is rated at 293 HP you would multiply 293 hp x the weight break of 10.5 plus add 170 lbs for driver. In B you would have to weigh 3,246.5 rounded to 3,240 is least you can be at the scales.
