hi can someone tell me the difference in the 130 and 143 tooth flywheels. what were they used on and clutch size thanks Rich

One is obviously bigger than the other , the 143 uses an 11" clutch , the 130 uses a 10.5" or a 10.95 scalloped. they use different bellhousing unless you have a Lakewood blowshield . 143 tooth is a big block Flywheel , some application of a truck might have had one behind a smallblock . 130 tooth was big block, smallblock and hemi starting in 70.

What car are you working on ?

i have a 130 tooth i used the 10.5 and 10.95 disc whit the same bolt pattern for the p.plate .what do you mean by scalloped. i was just trying to understand the diff

Thanks John
