Ma Mopar did some odd things like that. Looking in the factory serv. manual of how many springs they used in a particular application doesn't make much sense to me. In reality it's a combination of several things that affect how many springs you need.

BTW: here's a run down of how many springs my 1970 serv. manual shows each application should have

225---- 12 springs
318---- 12 springs
340---- 6 springs
383---- 8 springs
383HP- 6 springs
440HP- 10 springs
Hemi--- 12 springs
