I have this cam kit in a 400 smogger motor. 8/1 CR. I agree with all replies above, need to know more and what your goal is.
This is what I have: stock 1977 400 with 8/1 CR, performer intake, Edelbrock 800cfm carb, Stealth heads, Thumper cam kit, 1 5/8 long tube headers, Progression ignition...
I would like to finish this topic off and help someone with my experience. My ignition coil went bad and had a weak spark. Since 2015 I have changed 3 ignition boxes and two coils in this car and I had enough. I installed a Progression ignition system and got rid of the Chrysler ignition all...
To put an ending to this install and to help anyone else going forward, my issue was two fold. I went back through the set up and I was a couple degrees off, both in my crank rotation being set at 10* and not quite lined up on the black 10* marks on the distributor. Fixed all that and timing is...
I will need to go through the wiring. The car started out with the lean burn, switched to Mopar electric ignition before I bought it 28 years ago. I am switching to a Progression ignition unit that requires 12+ volts at all times. I ended up running a dedicated wire to the battery with a switch...
I went back and looked at the FSM for my car and the brown wire that is switched goes to the EGR timer not the ballast resister. The other brown wire out of the starter relay is the ballast resister bypass for starting.
This car starts and runs, but every switched 12v wire is showing ~11 volts...
The car is a 1977 Cordoba with 400. I am trying to find a switched wire that has full 12 volts. In checking the car every wire that is switched only has ~11 volts. I have went to the starter relay and I have 12.6 volts on the red wire but when I go to the brown wire that goes to the ballast...
I could not get the car to idle at 10*, had to crank it up to 1600rpm. I started at 20* and worked up to 35* at idle. Timing light was the same as app's reading until I went to 32* the app went to 31* and the timing light was 31*. I went to 34* and then 35* in the app and timing in app was 31*...
I got my Progression unit in and started. I must say that is has changed the way my car idles and reacts to throttle blips. I have not driven it yet as I have some other things that need sorted. One thing I ran across in trying to up the idle timing is it won't go farther than 31*. When I set...
I am looking at getting the Progression unit and wanting to know if the code you get is tied to you or the distributor? Can the code be transferred to a new owner, if you sell the car or motor?
Funknut - Any updates on how its working.
Just an update. It was not my timing light that quit, it was my ignition system. I went to start the motor up the next day to continue tuning the carb, it was missing and backfiring out the exhaust. Motor would not idle only run badly if given throttle, then it would not run at all. Pulled #1...
I agree with the cam not turning out like I wanted. A cam change will be done regardless what motor I do, as I am going to a roller cam.
I did work on the car yesterday and messed with the timing until my timing light quit working. I put the idle mixture back to the Eddy starting point of 2 1/2...
Again, thank you for the articles. The cam choice was because I was looking at the Hughes Whiplash cam which was suppose to help a low C/R engine. At the time, Hughes cam was out of stock and the Thumper cam had almost the same specs ( more lift on the whiplash). So that is why I went with it...
To answer some of the questions. I bought this carb new, and has been cleaned and rebuilt due to car sitting a few years. The jets are stock and metering rod are 2 steps richer, this was done when I was idling and driving on the transfer slot in the carb. I changed the metering springs per...
Timing is set at 26* (little higher than I thought it was set at.). The 2 1/2 turns on the idle set screws was what Edelbrock states is the factory (get you started) setting. I was shocked at reading 7/8 turns. I was asking if it was normal, so I will be turning the screws out.
493 MIke - How...
Have a Eddy AVS 800cfm carb on my stock smogger 77 400. The bottom end is stock with stealth heads, comp thumper cam, performer intake, headers, and AVS carb. I have been fighting this carb's idle on this set up for the 8 years since. It idles if I use the transition slot, but wants to die in...
Where is the best place to get a rebuilt brake booster. My car is a 77 Chrysler Cordoba and the factory service manual states I have the Bendix single diaphragm booster. Local auto parts store, online store, or ??? I get the hiss when pressing the pedal and my brake light comes on. TIA
