Craig-
The simple explanation is that the heavier the flywheel, the smoother the
engine will run, including acceleration. The heavy flywheel rotating
smoothes out minor fluctuations in engine speed, due to the greater inertia
from the greater mass. The lighter flywheel gives faster acceleration as the
rotating mass is smaller in weight & there is less inertia to overcome. Drag
race engines use the lightest possible components, i.e. aluminum rods &
pistons, that would not be suitable for normal street driving.
Your task is to find the compromise that gives you the acceleration you want
without giving you erratic rpms, which translates into a rough running
engine. I suggest you contact some of the Ford performance parts sellers
for their recommendations if you do not get the response you want from the
list.
Dan Masters, where are you?

Subject: aluminum flywheel information
I have a (unfinished) 302 Ford in my B, and I'm considering an aluminum
flywheel due to the light weight of the car. I've heard they are
'troublesome', but no reason was given, but I also saw a few aluminum
flywheels at the 1999 meet in Cleveland. Will somebode with actual
experience with one of 'our' cars with an aluminum flywheel please tell me
their experiences? I'd like to know what's wrong if that's the outcome, and
any positive points, too. The car will be used for spirited street driving,
with only occasional trips to a track, has a T5, a 2:71 (I think) mopar
rear
end, and should have in the range of potentially 300-350 hp, if those are
factors.
