2.76+100mm idler=stock belt?

[98Rsnake]

hey guys my tuner told me if i bought the billetflow nonslip 2.76 pulley and their one 100mm idler i could use my stock motorcraft belt. is this true? if so it would save me some money of buying a new belt. the one on the car now is practically brand new

I have the same combo and use the stock belt with no problems at all

I bought the 74.5 Gates green stripe for mine Friday, $40.96
My 33k mile motorcrap did fit fine but I didnt want any slip, the 74.5 belt was a little tougher to get on but it fit gooden tight and even makes more noise

My 1st combo was the 2.76 with the 4pc idler setup. It used the stock belt.
