Ya, that one statement rings true for me, which is why I really dislike my current Top Street Performance JM6701 distributor. Though what outweighs the GM HEI for me is that I cannot stand the look of it, I really can't. There might be time I'll reach a point where tying out the PerTronix ends up being a PITA that I'll be forced to a GM HEI or even back to points (but I'd have to be really pissed off and frustrated).

I actually have an extra module for the TSP distributor in my glove box, I got it months ago. I just did not expect to find the Vacuum Can not holding vacuum the other day. I think it is holding enough vacuum to operate but no telling how long it will hold up.

Your basic Pertronix unit installed in an early cast iron distributor will be a very good set up. The cast iron distributors run truer than any later GM units (included HEIs) as they have bigger bearings and the machining tolerances were tighter. Which means less spark scatter and a smoother idle and cruising.
The beauty of using the Pertronix is after completing the conversion you can put the parts you removed in a zip lock bag and stash it in the glove box and if the Pertronix ever fails you on the road, you can reinstall the points and get home.
