L.A 360..Magnum ?

KB107s/63cc alloy heads/.028 gasket/ with a [email protected]/ 750DP on an AirGap.
Falls together at about 10.7/176psi/.040Q/and altitude adjusted Effective Dcr of ~8.5@500ft.. Mine went 93 in the Eighth with 3.55s. I run dual 3" full-length pipes with NO crossover. The Wallace calculator says 433hp at 3457pounds. Your Dart is lighter, so it will post a higher trapspeed. If you're ok with a lil less power, I highly recommend the old Hughes HE2430AL, or something equivalent. That was a 270/276/110 and 223/[email protected]; better on the street, more bottom end, great fuel mileage, and only a lil slower . I set mine up to run 7000/7200 on the backside of the power-curve. Super much fun.
Can you do everyone here a favor and show us the time slip that you ran 93mph with your 360 in the 1/8th .

We look forward to seeing it.
