I've seen A LOT of posts about making HP with a 318-So why is it so ???

What HP does it take to run low 8's in the 1/8mi and high 12s in the 1/4mi in a '68 Dart with a 727 and 4.30 gears? That's what a stock bore and unported heads '93 Jeep Grand Cherokee 5.2L/318 did back when the M1 dual plane and single plane were all that was available for a carb conversion (late '90s). I used the single plane because of the gearing, but I had a dead "175K" MoPar converter in there (2400?) and a dreadful 60ft time. The engine screamed 3000-6500+ and everyone thought it was a 340. So they can run pretty fast in Magnum form, they are just ignored for the 5.9L/360 Mags. Back when I did it, it was harder to get a 5.9 and this one was basically free, a good warranty core from a "smoking" Jeep, and the breatsplate gasket on the kegger intake was just sucked in.
