http://www.randrperformance.com/dynoindex.htm Using Ron is great and provided Mark and I with a video down link so we could watch his dyno run live complete with audio.
My apologies to Mark as he is not dead (LateGreatU2) and it should have been LateBrakeU2. ![]()

Wow Rick,
That is impressive. Just wondering, since everybody knows that the distributor is the most important piece of the pie in building power, and since I haven't billed you yet for the rebuild, can I bill you more for this one than the last one I did for you? (JK...........Congrats!) |

Chris,
The services and knowledge you have helped me over the years is priceless so make it count! ![]() However, just a side note but we had to replace the points due to severe point bounce at anything over 5400 RPM. After the change it was great but what can you expect from an OEM set of points. ![]()

Interesting Dyno results. I recently had my 427 425 hp enjine on the Dyno by a local shop ,been around for a dogs age or more. I Used a stock dist and stock enjine ran the the motor on the Dyno.Then I installed in the orig dist Petronix electronic module.The Hp and torque diff was amazing with only instlling the petronix. If I find the dyno specs of both appplications I will post them. PJ |

I always used the Delco D112P HD points. Point bounce never seemed to be a problem with them. I picked up a couple of sets a few years ago from a local shop.

It's kind of funny because so long ago the magazines wrote 50 HP with a header switch on an LS-6. That in it's self is night and day in a motor. Rick if you get a chance, can you look at the dyno sheets that have the header vs manifolds and report back where they make their peak horsepower? I would assume the headers make its horsepower peak 200-300 RPM higher with the headers. On manifolds, we had peak HP at 6000RPM.
If you carry the compression, retarding the camshaft from the stock 6 degrees advance to 1-2 advance really makes the top end work. A guy named Weymouth has said he has seen it on a dyno and he is a Pontiac guy. Jim
