This is the original 318 motor in my 70 Dart, before I put a 360 in.
Stock 318,340 HiPo manifolds, Dual exhaust/H pipe, 4bbl Edl Performer, Edl 600cfm, Mopar Electronic Ign.
Stock 273 gear 8 3/4 rear, peg leg. 215/70-14 tires. This combo would roast the tires all the way down the street.
So yes, this is real world experience with 340 manifolds on a 318.
