Aluminium Flywheels
Anymore SB 4 spd drivers/racers with encounters with Flywheels?
Yes.
In my GTX with a 440 I went from a heavy SFI steel 11" flywheel to a 10.5" aluminum and the car turned from a sleepy rever to "HOLY SH*T WHY DIDN"T I DO THIS BEFORE"
A friend of mines 440 automatic car could just slowly pull away from me in a good race, after the GTX would b*tchslap that Sebring like he was in reverse.
The downside is you use to have to be a bit sharper on the gas pedal pulling away at a stop light due to the lack of energy being stored by the flywheel.
I used the same flywheel on the street with my 3500 lb 340 Dart- 10.5 squeeze with ported X heads, 528 mech cam with a TM5 intake with headers and a 625 Carter carb with 4.10 gears.
On street tires the car would run 13.0's at 112 mph.
I don't think I would run a very light flywheel with a 273/318 with a heavy car, but a 340/360/408 in a a-body would be fine. With a 340 and 3.23/3.55's it might not be to some peoples taste though as you would have to really be mindful taking off from a stop.
