True, but he’s running headers so he probably isn’t a restoration/date code/part number guy. If he has nothing on hand there is no reason to run a 727, except if he cares that it might have come with one originally. Racing or not, do you want to run a less efficient transmission? More power to the wheels, better mileage, safer, comparable cost. Valuable info no matter what you are doing with the car.
Not a numbers car nor stock in appearance/build but it is an original 340 car so I would assume had it originally been an automatic it would have had a 727. I do already have a stock 727 I planned on using and I do plan on putting a shift kit in it. I don't think I'll bother with the brackets
