My 70 440 auto R/T had that hood on it. I always thought the fresh air hood was on the B, and the Power Bulge hood was an R/T piece. I was at a friends shop and saw a pic of a 383 4 speed B he restored and he called it a B hood too. I told him about my R/T with the same hood so we argued about it for a bit and decided it was an option? I cut that car up in 90, and still have the hood, title, fender tag, broadcast sheet, and vin. Too bad it was a West Virginia rust bucket nobody wanted at the time.
