351W - what happens with smaller crankshaft pulley?

[MaineBroncoBeast]

Hi all,

The original crankshaft pulley is 4 bolt 3 v-groove with 8" diameter. I just received a new pulley that is 5 3/8" diameter. I'll have to send it back... it will effect the alternative charge, power steering, and water temp IMO.

I took the wire brushes to the original crankshaft pulley with the drill on hammer mode and stripped it clean to bright metal so good to go.

Yes, that is a big change in diameter. probably won't have any charging or power steering at idle.

Smaller crank pulley turns accessories slower.
