Water pump question

[Valiant72]

Does anyone know why they list a eight blade pump for a 360 with a two barrel but a 360 four barrel is a six blade pump? Shouldn't an eight blade push more water than a six blade? I bought a new pump for a 360 with A/C and it's got six blades so I was just curious. Thanks

Most of the cars with AC got the 8 blade, i would get the 8 blade if I were you.. Bet the books at the parts store are backwards, seen it a bunch. They used to say for 20+ years that my 64 Dart with a v8 had 11" drums, but if I tell them it is a 225 -6 then I could get 9" ers.

go figure!
