Which is the better of the two to replace points? Honestly the big bulky Hei looks kind of overkill on the side than a stock small distributor(with the petronix kit inside of it course)! But if it delivers more presice current i guess it will have to work!
Check out Tom Langdon's "mini-HEI"; he may have something for your application. i have one of these on my GMC, and so far it works really well--and looks good.
God's Peace to you.

I had a GM HEI on my motor but it looked way too large and not pretty. I went to the stock distributor and the Pertronics II system. After 5,000+ miles, it hasn't missed a beat and it starts with the first crank. Langdon's mini-hei
would be an update over the Pertronics system. Depends on your budget.

If the looks are the only thing keeping you from going with the GM HEI, you can fit a cap and external coil (1975-1976). Reduces the weight and height of the unit.
I'm using a mini-HEI on my 56 235 -- I like it. I have used Pertronix in the past with good luck on other vehicles. The reason I chose the HEI in this case was that I wanted a completely new distributor.
I used Pertronix 1 system on my 250, and it worked ok. I didn't really like the fact that you were supposed to use special coils, or pay attention to the resistance of the coil. I ended up ditching it and went with a stock HEI and external coil. Works perfectly, parts are cheap and extremely easy to find, and I don't have to worry about dealing with Pertronix if something goes wrong. Remeber, almost all of the V8 HEI parts interchange with the I6 HEI. Just my thoughts. Good luck. John
