The pertronix kit is very easy to install but you have to remove the distributor, I would go with the Ignitor III instead of the two as it isn't much more money but has multiple spark throughout the rpm and a rev limiter, if you're just cruising the II is fine, it's what I have and love it, they basically sell one kit that covers most GM V8s, you're not going to find one specifcally for your distributor, they make a standard and one for GM HEI.
