I’m beginning to see why you have two old trucks and sold all your cars. For the monkey type every day drivers you are right by saying the cams aren’t degreed in. First off Mopar or other manufacturers could care less if it’s right or wrong. Performance cars are different and yours and others statements explain why some cars run and some don’t. I dought if 90% of the warranty shop guys could degree in a cam or even file fit a set of rings. Lol 😂 stick to what you do best

Some of us that have done a lot of this stuff also know to take a quick look at gears dot to dot and check #1 cyl lifters to check for and even overlap of ex closing and intake opening. This does apply to most chevs and mopar v-8's, but certainly not all. I've corrected, as many here have, the 3 way screwups when friends use wrong markings and are 2 1/2 teeth off after their install. Goodys got it covered so it's done, right?

Yep, and I'm happy for him. I'm sure it was plenty frustrating finding the causes. But it would be nice for all that helped, and even those of us that only followed the thread to know specifically what those causes were.

I have been hesitant to say "this" fixed since I have very limited mileage on it. It's been a combination of three things that I can attribute it to.

1)Distributor air gap - Fixing this fixed the sharp jump in rpm drop seen in the video. Replacing the distributor seemed to offer no further improvement.

2)Secondary venturis - Upon rebuilding the carb, I must have swapped sides on the secondary venturis. Apparently they aren't poka-yoked, like I thought.

3) Fuel volume - I still had leaning out issues after sustained high load, I had a pair of higher flow needle & seat assemblies in a donor carb that I transferred over, those seemed to help that.

The last run pulled much better but it was very fat [10:1], so I need to back out the jetting the other way. I may have 5-10 miles on it running "well", we'll see if anything comes back. The truck gets very limited use.

I’m beginning to see why you have two old trucks and sold all your cars. For the monkey type every day drivers you are right by saying the cams aren’t degreed in. First off Mopar or other manufacturers could care less if it’s right or wrong. Performance cars are different and yours and others statements explain why some cars run and some don’t. I dought if 90% of the warranty shop guys could degree in a cam or even file fit a set of rings. Lol 😂 stick to what you do best



Not quite sure how to take your last statement. Is that an insult? Because you really don't know anything about me or my abilities. I sold my car because I'm nearly 62 years old, working 60 hours, 6 days a week. I'm looking to retire soon and just don't have the enthusiasm or drive to race anymore. I built my 4 link, strut front end car with a friend in a carport. I built my own engine and did much of the machine work myself at another friends shop. We cut the rear end housing down and stretched the wheel wells. We did all the tin work and plumbing. Just because I make a living working on imports doesn't mean that's all I know or all I do best. Could my car have been faster? Sure, but so much of it was a total compromise because I used what I had or what I got for cheap. But the car would hook in a car wash.


You seem to have some good running cars and since you are retired (and as I recall it's not from anything automotive related so is that what you do best?) they should, you have plenty of time that I don't. I keep the trucks because I like them. I enjoy driving them and working them and working on them. They will suit me well when I move to the mountains of West Virginia where there isn't any race tracks anyway.


Then there's the other proctologist in this thread taking shots at me. You know the guy that fosters pit bulls and laughed at me when I told him to be sure his insurance is paid up? Yeah well since my GF was attacked the medical bills are damn near $200K, she has lost her job because she can't work so there is no more health insurance or long term disability because the company paid for that. She can't do the yard work she did before so I have to take care of that as well. And to top it all off SS turned down her disability claim so now we have to pay $6K to a lawyer to try and get that accepted. But it gets better, it takes at least 6 months for that process and if it has to go to court that will take at least 2 years.

Seems like so many people here like to make assumptions, jump to conclusions and then look down their noses from their high horses it's just pathetic.

Glad he solved his problem! When I was a young lad, with a 2 year old 69 Roadrunner, I was just starting to learn about cars and engines. Somehow, I can't really remember how, The wire to the points shorted out. It was obvious that it was fried and I went to the parts house and got a new wire. I started it up and it ran just fine, but when it got over three grand, it just laid over like it was out of gas. I screwed with the carb and checked the fuel pump- no joy. After checking out lots of unrelated things, I finally pulled the cap and took a close look at the points. You guessed it, the short had heated the points enough that it took the temper out of the spring(it was blue from the heat). Those points were floating like crazy over 3K. I threw in a spare set and the problem was solved. We have all been there at one time or another, nobody was born a master mechanic. We need to bring back the civility to this forum, we are all here to learn!

I would have a look at the PTK linkage and make sure it is not keeping it from getting a FULL WOT.

I kicked myself for finding my truck would not pull any thing over 3500 rpm once. I tried a bunch of crap to find I goofed the linkage adjustment.

worked by hand under hood as I did not ever blip it fully open to see it. found it with a helper on the pedal while I watched and adjusted it out.

surly not your issue but thought I would mention it as I did not see any comment about throttle/PTK adjustment check for a full throttle.

the one piece rods on the trucks suck for adjusting and I swap them to a nice 3 piece set up.

my 85 runs a stock q-jet-intake/1 piece linkage set up and easy to only get 3/4 of throttle with it if not watching it.

I throw my single van door/ign key on a red lanyard around my neck & if I am bending over something I toss it over around to my back side, well the other day I spent a considerable amt of time looking for it till the office mgr out here pointed it out when she asked me what I was looking for. When she said that I was just kidding her of course I had to agree with her!

That said, the engine still struggles around 4,000rpm. I would say it's not cured, but much better than it was initially.

I'll leave it as is until I can get some other form of carburetor on it, runs like a top otherwise. I've been wanting to get a Holley Sniper kit for it anyway..
