Would you happen to know what extension is required for the Amazon pan?

Just my 2 cents worth, but It sounds like you might have a really bad vacuum leak. Could a backfire have blown off a cap? I’m running a late low compression 440 with the Whiplash cam and mine carries right on 10 pounds of vacuum at idle. I run a QuickFuel 780 with a 5.0 power valve.

I’ll give it a shot tomorrow, thank you more than you know!

As much as I dread removing the wiring harnesses I. Think you are right. I did inspect and clean the under dash harness about rive or six years ago when I had the instrument cluster restored. Unfortunately with my head injury I can’t remember much of what I did. It sucks! I have done so many...

Thanks once again. The engine has a good ground to the firewall. The switch goes directly from the battery to the coil.

So the impossible just happened. I started the car this morning and is was running bad again. When I got to the gas station I turned the key to the off position and the engine shut off without turning off the bypass switch! The negative side of the coil is still connected to the factory wiring...

Update: I found that I was only getting 10.4 volts to the ballast resistor and 5.6 to the coil and 3.5 out of the coil. I did a little research and found that a MSD Blaster II coil handle 12 volts as long as you’re not using points. I am still skeptical of this, however I ran a wire from the...

Thank you for your reply! I believe I have tried that in the past but I’ll give it another shot. Right now I’m having an issue with even getting power out of the bulkhead. It must be the main power supply wire, normally the fuseable link, at the bulkhead. Just very difficult for me to get in...

Thank you so much for your reply! First the engine is fresh, I knocked out every bit of flashing I could find on both the block and heads. I pressure washed the entire block and heads until all the water jackets ran clean. The radiator is new and cools just like the aluminum one I replaced. I...

No video right now other than at idle and I don’t think that the site will let me upload video. One thing I forgot to mention is that the tach will jump around. The instrument cluster was restored about five years ago by Redline and upgraded to modern ignition systems. These are the shorty plugs...

The misfire is across all cylinders, it has been there with various different cylinder heads, it does it most of the time, at higher rpm’s under wide open throttle it seems to get better, but with Flowmaster 40’s it can be hard to tell. Timing has been set all across the board but is now at 34...

Thanks Gus, but I did, this thing is a nightmare.

First off, I have a head injury and can forget some major stuff and have difficulty communicating. I also have to do this multiple times to get it right. However, I have owned the car since 1980 and know it very well. The engine has a bad misfire and overheats. I have eliminated all of the...

Awesome, thank you very much!

I imagine that the procedure is the same for a 73 Roadrunner?. Mine is my first car, I got it when I was 16 in 1980. It is very nice and I'm really worried I'm gonna screw it up! I have to replace the ignition switch wiring harness and I really don't know the procedure. If anyone has any...
