How can you tell the weight of a flywheel. I am installing a t-5 in my project roadster and want to be sure I am installing the correct one. Thanks
You can look at the size of the weights the 50 Oz physically has more material then the 28 Oz but if you have nothing to compare it too, its not that good. Does the flywheel/flexplate you are replacing it with have any numbers on it?
No, I bought the flywheel from a guy and I can't remember if he had said it was a 28 oz or a 50 oz. Because at the time I was going with a different motor and he had said the weight for the crank was different on an earlier motor.
The only other way I could think of right off the bat is what kind of clutch does it use? From the information I have found all of the 50oz flywheels in front of a T5 use a diaphram clutch(I know my flywheel definitely does..even though its not a T5), now this is important to remember because the diaphram clutches use metric bolts whereas the 3 finger clutches on the 28oz flywheels use standard bolts. Also one thing to watch out for In 1985 the flywheel for a 302 used a 10 inch pressure plate. In 1986 they moved up to 10.5 in pressure plate so if you do have a 50oz flywheel make sure you get the right clutch because the clutch wont interchange between the different years, and if you have the 50oz flywheel and you plan to use it with a diaphram clutch remember to get the dowel pin kit you dont want the clutch to chatter.
Here is a good pic for you on the different weights, as you can guess the one with the bigger chunk of metal in the back is the 50oz weight, maybe this will help you decipher it a little bit.
an engine machine shop that does balancing should be able to help you figure it out. expecialy one that does lots of ford v8s
