okay, under drive pulley set(crank and alternator)
arrived from summit today.
it said "instruction included" so I thought a noob
like me would figure out..
but all it say is pull the old pulley out,
and put the new one in!

I mean, ok that I guess I can do
but what would be the new belt's measurement
after installation?

I am running a 3.1L camaro 1991,
with all the accesories including A/C and air pump.

another thing is the alternator pulley looks like
the size are same as the old one, so whats
the point in there?

I found someone putting a link to aspracing.com
or something which I couldnt view the web right
maybe becaz I use firefox or something..
if any1 can give me the measurement,
greatly apprciated, thanks!

 

i called asp when I installed mine and the belt needs to be 2.5" shorter then stock

 

hey cool man.
but does that only apply to the pulley u bought from
asp though?
Ill try autozone tomorrow and ask for a 2.5" shorter one,
and see if it'll work.. thanks again

 

If they are the same size as the ASP set, you'll need belt #980K6.
