And if you're trying to stay "stock", at least in 1970, the 383's got the 11" clutch and the 440/Hemi's got the 10-1/2".
Incorrect, in 1970 and up B bodies and E bodies with B , RB or the Hemi all used the same bellhousing that required the 130 tooth flywheel. This flywheel only has a pattern for a 10.5" B+B pressure plate which can use a 10.5 or scalloped 10.95" clutch assembly.
Prior to 1970 383 and 440 used the same bell with a 143 tooth wheel while the Hemi had it's on bell, 172 tooth wheel and special starter ... 68 and 69 anyway , 65-67 ??
