Big horsepower 318 builds

One other thin about the 318. Many years ago, Hot Rod or Car Craft magazine (I don't remember which), printed an article that challenged builders to get maximum HP with a $2500 budget from a Mopar 318, 350 Chebby and a Small block Ford (351 Windsor I think). The 318 won. I don't remember any other details, but the 318 won.

LA - benefits
High nickel alloy [pre-1977]
High cam centerline height of 6.125"- Much higher than other small blocks and also higher than
the Mopar big blocks including the Hemi 426
Stock 6.123 inch rods the teen offers a rod ratio the competition would die for [1.85:1]
Valves are inclined at a advantageous 18 degree angle
Higher cam centerline clears long strokes easily and therefore allows more displacement
