I have run steel and aluminium flywheels in the same Challenger with a 3.55 gear. One was a 416 stroker that made 490lbs torque, the other a 346 with a 525 solid cam. Both engines were much better on the STREET with the steel flywheel. Most notably say in a parking lot in first gear at idle engine, would roll making the car sort of buck. A quick in with the clutch and blip of the throttle cures it. Both engines would not do this surge with the steel flywheel.
Aluminium flywheel on a 440 engine and 4.10 gears that I had in a 68 Cuda had no streetability issues like the small blocks had. Cubic inches and lighter weight will make a difference.
