HOLD ON A MINUTE!

It is not well known that the front pulley and hub are a MATCHED

ASSEMBLY.

The timing marks on the stamped steel pulley are not consistently

timed to

the hole pattern. You cannot safely mix and match pulleys and hubs.

Some of

the pulleys are marked pretty close to the same, many are not. You

need to

get the position of the timing marks relative to the keyway in the

hub, not

the four bolt pattern.

Been there, done that!

Is the relation between the keyway and the timing marks consistent for the

same

year (88) engines.
In other words if I buy a set (pulley and hub) I should get the proper

timing

marks for my engine.
Where is the TDC mark in relation to the keyway?
Thanks

I wonder how all this pertains to the Race Beat after market pulleys.  I
purchased the dual belt Race Beat pulley with marks to 20 degrees BTC. And
10 degrees ATC. I did not check for the keyway at 9 O'clock.
