Pulley Interchange. Novi to ATI

[Diabolic]

I called ATi and they said their pullys wouldn't fit a Novi 2000. They said the Procharger Pulleys were .877" at the center hole and the Keyways were 1/8th
inch. I measured my Novi pulley and it too has a .877" center hole and the dual keyways are 1/8th". I'm not sure why they tell me they will not interchange so I'm wanting to see if anyone has ever done this before.

Probably for liability issues.

So you will buy one of theirs... check the mount depth. That might be slightly different.

could be the seal surface diameter or a different offset

I've been looking for a 3" or 3.2" Reichard Racing Ultra Grip pulley for a year without success. I found a 3" for the ATI yesterday, so I really want to buy it.

blower pulleys

my mild to wild pulley set. I found the grip pulley at a swap meet last year. It was the correct bore and key for my B&M, everything else has to be changed, the seal surface was too small the depth was too long and the face stuck out so far it rubbed my hood, Luckly I have a small lathe to fix it all.
