Oh I'm pretty sure that 4100 pound Galaxie was running more than a 40 pound flywheel.
I hear what your saying Chas. Here's a rule of thumb I like. Every pound of ROTATING weight is worth three pounds of static weight.
I'm all ready considering some major changes with my car, down the road. 5 speed for one thing, possible top end with different heads, single four intake, light weight flywheel, different cam, more of a road racing setup. AFTER I get moved and settled in, right now I'm in the middle of packing. This was the worst possible time for me to be playing with the car, I really shot myself in the foot this time.
I recently bought a second set of wheels (four) so I can mount some race tires and make it easy to quickly change from street to track. Can't wait to get on a track again (none on Oahu).
