Tell us a little more about your engine. Stock compression ratio? Stock pistons and rods? Heads? 6 rib drive system or 8 rib?
If it's all stock, an 8 rib 3.4 pulley with a D1SC is going to destroy your engine in a day or less!

If its the 8 rib ATI setup then the pulley size you posted will see 14psi or so. Im running a 4.25 pulley seeing 7.5-8psi now with the stock 8 rib ATI crank pulley which is 7.65". Check the crank pulley size before you run that small 8 rib sc pulley.

The difference between the 6 rib and 8 rib ATI is the crank pulley size. The 8 rib has a larger dia size crank pulley which will increase boost. That is why running the same blower pulley size from a 6 rib on an 8 rib kit will give u more boost.
For example, 7-8psi on a 6 rib for my car was giving with a 3.60 SC pulley and the small 6 rib crank pulley.
7-8psi on the 8 rib was giving with a 4.25 pulley and the larger crank pulley which is 7.65".
I hope this explains the difference.
