Good long tubes are worth 25-35 ft. lbs. down in the low/mid range on a decent small block, sometimes more on some combos. Probably less on a milder combo with cats.
I do remember doing a 458 hp 383 LT1 in my 93 Vette, and Myron Cottrell at TPIS begging me not to run shorties, which I wanted for legality here in California. He quoted the same numbers and seem to be pretty close to what I've seen through the years.
