Anyone double spring the points like years ago?

i though there were some hd-points that would be stable at higher rpm available for the corvette hipo engines that were spec'ed as such 
I see that paragon has two sets of points, one is listed as HI.Perf. & & B/B.i though there were some hd-points that would be stable at higher rpm available for the corvette hipo engines that were spec'ed as such

Summit racing also list one: http://www.summitracing.com/parts/acc-110129/overview/make/chevrolet This is listed as a 32 oz kit and they have a cheaper one that is listed as a 23 oz kit whatever that means? Maybe it means spring tensions or something like that.
I wonder if they are the same. Anyone care to recommend one over the other?

Never heard of double springing points.
The specs are for spring pressure. If you're planning to run your motor to the redline a lot, then get the H-D points. They will follow the distributor cam lobes better and help prevent misfiring and spark scatter (when the timing jumps around due to point bounce) at high RPM. The extra spring tension will wear the rubbing block on the points quicker so you have to adjust them more often. Regular street driving, the standard points will be fine.

Re: Double spring,
James, we used to do this back in the day. It cut down points floating at high RPM. When electronic systems came online, I stopped. The extra spring tension wore things out quick, and was pretty rough on the distributor shaft.
Yes, There is something in the corvette literature about this, as Vince suggested. Special points that were developed just prior to the transistorized ignition or something like that...maybe points that were used with the Gen 1 transistorized ignition. Remember, that was the one that didn't use the inductor coil... Still used points as a switch, but had the external control module. I thought they were just single spring with a heavier spring rating, though.
But it has been awhile

32 oz spring, have to carry a dwell meter and allen wrench around with you. I used to d all that stuff, then discovered the Mallory points revved higher and didn't wear down the rubbing block.

the accel unit shown in the link said it was a 48oz. unit with reinforced arm and blocks,
this would appear to be the hot ticket if points type set-up is required/needed.
there are better lube options now to prolong the block life also..

James.
The Accel 8104 point sets have 32oz springs and are good up to and over 8000rpm. I assume that is way more than you need.
When I was still using points, "you really should think about a Pertronix swap," I would look for the Accel sets on ebay and buy them for 10-12 dollars a set. summit and them sell them for $35.00 I think.
I still have several new sets laying around here. the only downside is you need to reset your dwell about every 3-4 weeks because the phenolic wear piece wears quickly because of the highr spring pressure.
But, they are quality ignition parts, and better than the crap they sell over the counter now days.

Thanks for all the advice guys. I see there are 23, 32, and 48 oz springs. Mallory has a 32 that is suppose to be good up to 5000rpm and a 48 with a special rubbing block that is suppose to be good up to 8000 rpms. I don't want to have shaft problems. Thinking I should go with the Mallory and the 32 oz spring.

Install a Pertronix module,bolts right up where the condenser mounts on the distributor , use a black stock appearing Pertronix 40 volt coil and ran a 12 volt wire from the fuse block ignition terminal to the coil to make it work and ran it parallel to the ballest wire , not eliminating ballest wire completely if I wanted to go back to the points ,which I will never probly do. Ive used this Pertrnoix unit for 12 years with no issues , easy and simple to install and no maintance like points.
Well, gents, here is your laugh for the day, or maybe for the week.
Way back when, I remember reading an article somewhere that gave the hot tip of wedging some foam rubber on the points to assist the spring and get extra rpm capability.
Yours truly took the bait, hook, line and sinker and did it. Didn't notice any improvement at all, and was too novice to know that the rebound capability of the foam was nowhere near that of the spring on the points.
