WHat is the difference between these 2?
I have a 455 swap from a 350. Orig owner I think used all the orig pulleys, like your supposed to. Problem is my KH pulley is wobbling too much imo. Made my own runout jig, and its slightly warped...even on a flat surface you can tell.

I see parts place has a KA, but hard to find a KH repop. The KA ad says for a AC car, but mine is a AC car (71 Cutlass S), and has a KH.

My pulleys are -
KH Pwr str
KO wtr pump
KB crank

Thx.

 

database says KA is press on
KH is keyed and nut retained.

There are zillions of KH used 2g pulleys around, why not get a good used factory correct part that fits and works right?

 

Thx for the input. If you see link below, the KA in the link is keyed and nut retained too.

As for KH pulleys being easily found, I have not seen them out on web too much at all. Ive been looking.

 

I'm shipping a pump with the KH pulley,in about an hour.It is retained by the nut.

 

Seller information
thepartsplaceinc

therefore, presumably, reproduction
Shall we go over again how reproduction parts seldom match the original, often in very significant ways?

I have 2 or 3 KH's on the shelf, ready for a new home. Just ask.
Well, just ask... and grease my palm a little [or a lot].
