Ok, I am still confused as to why I need to record the throttle position. It's arbitrary at best and these rochesters aren't exacting enough for very much precision. Explain in detail why throttle position (per test) matters. I wish I had a protractor type control, but the very best I can do is measure how far out of the socket the cable is with a tape measure. Is this still a good idea to you?
You NEVER EVER gap an HEI to .035. Its way too little gap and is totally not recommended. It would be like gapping a stock ignition to .025. It makes no sense whatsoever. If I don't understand it the way you do, explain?
THIS PARTICULAR HEI is totally different than anything else out there because of its 'small body' nature. The stock distributor cap, rotor and wires are used and there is very little room in that cap for the extra high voltage electrical impulses to fire without causing a crossfire condition. I know all this because its been fully explained to me by the guru. He says there is no worries of any of that with this system if it's set up correctly.
So what I CAN do is get a different set of plugs with larger gap characteristics and try them at .060 for starters. I am a little leary of getting too carried away with gap since that fire has to go somewhere, and if it doesn't jump the gap it can go back down the plug wires and do damage to something.
Can you recommend a spark plug that is the right threads and correct for wider gaps?
The codgers I am talking about are adamant that any engine from that era (1941 to 1962) runs better with .016 and .040 respectively. They say forget about the book, just do it and watch the difference it makes. This is a good time to see if they know something I don't. That part is just out of curiosity.
How did you compute the 46.7 rpm for every 1 mph? That would be interesting to put in the article.
