The Vortech 2A038 8 rib pulleys have a different backspacing on them than the stock 3.20 jackshaft pulley that comes with the Stillen kit. It makes the jackshaft pulley stick out from what I can guesstimate, about 5 mm's towards the front of the engine as shown in the pic that "cupcake" posted.

What I'm trying to accomplish is to replace my 3.20 jackshaft pulley with the same size high traction pulley.

Oh shiat, I just noticed this is my 666th post, the devil made me do it.
