Charger Discussion / Re: 74 318 4 speed
Last post by Mike DC - September 15, 2025, 06:59:01 PMI'm not the expert on production data. But IIRC they didn't keep track of stuff that way.
They recorded how many 4spd cars they built, but not how many of them were with which motor. They kept track of how many 318 cars they built, but not how many of them had 4spds. Etc.

Last post by 496polara - September 15, 2025, 08:45:48 AMThankfully non ethanol 93 and 89 are available at multiple stations within 5 miles from me. All three carb'd cars get this and the lawnmower too.
I have an 01 mustang gt that gets driven so infrequently it gets non ethanol too.

Last post by Kern Dog - September 15, 2025, 12:41:16 AMQuote from: 426HemiChick on September 14, 2025, 08:27:37 PMBack in the late 60's we ran our 68 Hemi RR and 69 Dodge 440 Six-Pack on Sunoco 260 pump gas.
Ah, back when MEN were MEN and women were women...The good old days.
Regarding the original topic, it is interesting how one can do everything right and have a car that knocks while in other instances, you can do a lot of things wrong and it runs fine.
When I built my first stroked 440, Hensely Performance guys said it would run fine on pump gas. It didn't.
In California, the best we get at the pump is 91 octane with "up to 10% ethanol".
The 440/493 was at 10.8 to 1. It knocked at anything over 1/2 throttle even with the timing limited to 31 degrees. I tried slowing the advance curve, tried 2 different bigger cams but the only thing that helped was higher octane gas. I was able to get 100, 104 and 110 octane gas in 5 gallon pails at the local NAPA store. It barely knocked on the 104 but the 110 totally eliminated it. I chose to change to thicker head gaskets to lower the compression to 10.17 to 1.
From there, it ran fine on 91. Years later the cam lost a few lobes so I pulled the engine and used this as an excuse to go through it all. I replaced the pistons with a set of ICON dished ones from the 440 Source. I'm now at 9.8 to 1 and can run 89 octane without knocking. I have not tried 87.

I have known several people that have run 100 LL Avgas in their pre no-lead cars.
Back in the late 60's we ran our 68 Hemi RR and 69 Dodge 440 Six-Pack on Sunoco 260 pump gas. Think we were paying about $0.36.9 / gal back then.
It was still available in 1978 but know nothing about it after that.
Have fun.

Electric, Gauges, & Lights / Re: Improving the brightness o...
Last post by Kern Dog - September 14, 2025, 03:30:31 AMI replaced the turn signal switch and gained brake lights but the turn signals up front are weird. I have a left turn signal but not a right. The flashers make the taillights blink but not the front.
The taillights are brighter at all times though. Below, the car on the LEFT has stock taillight housings, the car on the right has the painted housings.
Can you tell a difference?
I was here alone and could not press the brake on both cars to get a picture of the brake lights. I turned the flashers on in both cars, hoping to snap a couple of pictures as they both were brighter from the flasher...
I don't know if I got it right. The car on the right looks a lot brighter though.
