So you have a 3800-5000 stall convertor, the engine won't lock the convertor until it hits that number so why do you have the timing come all in at 2000? Weak springs and a radical idle will cause the timing to bounce around.
4sp? your probably never going to drop that clutch under 3000RPM

It takes 2 conditions to make an engine detonate too much HEAT and PRESSURE if either one of these conditions is not present then it wont detonate.
The lower the fuel octane, higher the combustion chamber temps the more susceptible to detonation.
I believe you said this was a 69 engine?
Do you...
I'm with AR67, Take off the Air Cleaner, look in the carb, watch the booster for dripping fuel. At idle there should be no fuel dripping from the booster.
Check the float levels, make sure your Idle Air Bleeds are not plugged (the outer ones)
Pull the plugs and look for the anomaly it show as...

This "Best in Industry" product has been available since Feb. 2012 and every one of the nearly 7,000 units sold are still operating flawlessly Worldwide. It's easy to give you a 5 Year warranty, we don't have any failures!
Thanks...
Ok, So Revco Ignition? that has Google and I both baffled, what is it? Where did it come from? Is it mag trigger or Hall effect? Is it a self contained ready to Run or does it connect to a box?
Where did they set the initial timing? Where's the total timing? What RPM is it all coming in at...
All 100% Chinese components we've set up and upgraded hundreds of them, the ECU retards the timing 8* (some more) starting at 3200 and by 5200 they fall off to unacceptable output levels. Ballast resisters burn up, most have Aluminum contact caps, poor fitting wiring harness, wrong springs and...
"Climbing the HEMI Mountain"
Well written tech article using our FBO-J685 limiter plate.
We had no input on this article and paid no one to write or print it.
Please Re-Read the article, it was written by the Engineer who was involved in the design and development for GM.
This is NOT an argument for ported or constant it is a clear and exact article on how the different vacuum sources work, their specific applications and how they affect your timing...
Start with a Volt Meter
+ side of coil cranking 10-12V
+ side of coil in run position 5-7V If your using the ballast resistor.
I have never used starting fluid on any gas engine and never would.
Few Tips.....
*You can use your timing light and clip it on each wire and crank the engine it will...
I found this article on ChevelleStuff.Net I don't know the author so I can't give valid credit.
I have tried to explain this theory to 1000's of callers over the years and most get it. However, there's still a constant stream of posts all over the web that still want to argue about how the...
