What timing chain do you have
To my knowledge the spacers that are sent with the timing chain is what causes the pulley to have to be machined.
I stuck with the stock chain (car had 18K on it) and stock oil pump, if you have low miles and aren't going with a huge bump stick the stock stuff including retainers is fine in my opinion.
I decided to save the 400+ dollars on the items above for when I go with a bigger cam and potentially AFR heads next year.

Did my Rollmaster double with the ASP pulley and no problems. The vettes need to watch out, haven't heard of any problems with the F-Bodies.

Ditto and got my pulley from Thunder racing
