72 Dart Swinger 3.6L Pentastar +T5
I was curious to see how the 3.6L Torque and Hp curves compared to common 340/360. I couldn't find a decent factory dyno curve of an old combo but the factory used a different SAE test standard back then anyway, so I replotted a 1999 5.9l Magnum.
Stock for Stock, the Pentastar loses out between 1500-4000rpm but kicks in after 4k and pulls hard to its peak Hp at ~6500rpm.
At 5000rpm, the little 3.6L is up a whopping 150ft-lb and 20hp over the 360!
By 6000rpm the Pentastar hits its peak Hp but the 360 went home early.
4.56 rear end should help out the low speed torque and keep the revs in the power band, while the .63 over drive will turn those rear gears into a cruise friendly 2.87,,,
