The factory balancer doesn't look like its slipped in comparison to your new balancer. Look at the keyway on both balancers and the timing mark of 0 degrees on both balancers. They are the same. How are you timing your engine?

I borrowed a friends timing light and that what I'm using to time the motor sorry for the late response.

Okay fellas I know it's late but here's some videos for y'all to try and assist me if possible.

First one will be at 8 degrees advance not sure if you can hear it audible through video but sounds a little like its stumbling. I am doing like a power brake since I'm not driving it.

2nd video is at excatly 0 degrees timing and doing again a power brake and it doesn't seem like it skips a beat.

3rd video is to show y'all exactly how much throttle I'm putting into it.

Is there anyway y'all can help and give me advice on whether it needs to be timed differently and I'm also adding in a picture of what the #1 plug looks like just for help as well.

I do owe a big thanks for 67 c10 guy for coming over and helping me work on the truck and get everything set up good as new.


Here's pictures of the install from today enjoy guys

I'm not sure what procedure you are using to time your truck...
1. Warm the truck up to operating temp.

2. Pull your vacuum advance hose from the carb and plug the port on the carb.

3. Utilizing a timing light, see what you have the timing set at. (If you set the timing with the vacuum advance hooked up to the carb you are running your timing super retarded.)

4. Loosen the distributor clamp. Advance the timing 12 to 14 degrees initial. (I ran mine at 14 degrees advanced initial, so once you hook up your vacuum advance canister you will have about 26-30 degrees of advance/ ignition lead at idle.)

5. Tighten down the distributor clamp, recheck your timing and reconnect your vacuum advance canister.

You can also recurve your HEI distributor, which will wake up your truck. I used the lightest springs in the kit and my advance was all in by 2000 RPM. Its personal preference for you as well as if your engine will tolerate it. Some people like these kits, some don't. I guess I just want to see you get your truck running so you can start to make some real progress. Your plugs indicate you are running rich. You could safely jet down your carb, but that's a whole other story.... Good luck, hope this helps tremendously!!!

Thanks Jabes!

I always before I messed with timing got the truck to operating temp before I did anything.

On revurving my HEI I think I might wait on that, just for the simple fact I really would like to get the truck running as "flawless" as can be and then I'll tinker with other parts as well.

We left the cord on that carb port but had it plugged so does that matter? Also should I/we have plugged the vacuum advance canister? Or is that fine to stay unplugged?

I just watched the videos you posted and I can't really hear anything wrong with it on either video. I do notice your idle rpm sounds higher on the 0 degree video. If you're thinking the engine sounds like it's not running right because of the different engine speeds, try adjusting your idle speed to about 800-1000 RPM in park or neutral at any timing setup. Tap the throttle a couple times to make sure it seats and recheck timing and idle RPM. When you put the truck in gear, it should be idling around 600-800 RPM (higher if it doesn't like to run that low, but usually just under 1000 RPM).

If your idle RPM is different with the different timing setups, you won't really be able to tell which runs better. If Idle is too low, the engine will sound like it wants to die.

Hopefully I'm not missing something in the videos your trying to get us to hear.

[77ChevySharkBite]

I'm not sure if you watched but the 3rd video is just to tell me pushing down the gas and it's at 8 degrees advance, maybe I'll have to retake some videos and get closer to the exhaust and carb, but is it just me or does it sound like it has a sputter?

[knomadd]

I watched all three videos. I can hear the lope of the cam, but I don't notice a sputter or stumble. Maybe I just can't hear it in the video. I'm at work so I can't turn it up really loud.

[77ChevySharkBite]

Yeah it's all good no worries Duane, my only issue still what seems odd to be is that at 0 timing it turns over fine but now I will admit that on 8 degrees advance it's not as bad still takes about half a crank to start but not horrible like it once was so maybe I should kick it to about 6 degrees advance?

[knomadd]

Without being there and seeing exactly what's going on myself, I can't give you an honest opinion on what you "should" do. All I can say is set it where you think it runs best. If you notice small issues when its running/driving/starting/shutting off, then you may tweak it some more until you get it just right. If timing isn't fixing the issues, then it might be something more.

[77ChevySharkBite]

Thanks Duane!! I understand you can only do so much I guess this is where I get to understand my motor really really good!

[UPNADM]

Have you replaced or checked the slack in your timing chain?

[77ChevySharkBite]

I replaced the timing set completely, but I think I might have found my flaw today.

When I put the motor at 8 degrees advance I've never really touched the idle to bring it up, so what I'm going to do is bring that idle up to probably around 1-1,500k and see how the motor likes it there and then take the truck for a spin and test it see what it likes.

[Sodell]

did you set your rpm's when you set the timing?

[77ChevySharkBite]

I did when I set it at 0 but when it was advanced 8° I didn't touch it which I should have

[chevybuilder18]

Best timing will give you the best mileage, and performance.. hopefully you get this matter fixed.

Yep, it's a back and forth. Timing-RPM's ect...

[77ChevySharkBite]

Sorry for no updates lately guys.

Wedding planning, family dinners, shopping for wedding stuff, rain and cold weather

A lot of excuses but real life, no the little small update is the truck is running great I got it warmed up on Thursday or Friday, and really messed with the timing set it at 8* advance and it runs like a dream, I think the carb is a tad rich cause when I take off it kind of sputters but the heavier I lay into it it wont, so I think it's just the initial so going to mess with that next.

Other than that not much going on weather here in Texas is getting very random now and hard to dedicate to work outside in 40* weather, going to try and get the truck back in it's home this week/weekend that way I can tinker with it some and not freeze my butt off.

Next project to do on the truck I don't know yet, thinking really work towards trying to get it on the road and be able to drive it a little to be able to enjoy it, probably going to start doing some maintenance items on it too tidy things up.

[knomadd]

glad it's running better for you. Hope the rest it pretty simple. Did you change your plugs, wires, cap and rotor when you did that long list of parts swapping on your engine? It might help if you haven't yet. Not that it will take care of everything, but it can't hurt.

[77ChevySharkBite]

Well I had put new plugs when I put the headers on, probably wouldn't hurt to put a new set. As far as the rotor/cap and wires I haven't changed those but I do want to change them, as that would complete a full tune-up and get it running even better.

I'm trying to be very careful with the motor right now cause we ran the head numbers and I don't recall them at the moment but short story short the heads on my truck are known for cracking so going to have to kind of take it easy on the truck from here on out until I can scoop up some new heads. Maybe next years birthday present to myself?

[77ChevySharkBite]

Well I hope everyone had a good and Happy Thanksgiving, nothing much really happened went to my first ever autorama and all I can say is wow. I wish I had taken a picture of it but there was a twin turboed old school t-bird that won the lone star cup for autorama, and it was a beauty but here's some pictures I snapped this past weekend might see doubles and if you do I apologize. This was one of the baddest shows I've ever been to and I could of taken pictures of every single car cause there was mild to wild but I took pictures of the ones that stood out most to me.

Bare with me have to redo the links.

[Remon.]

Pretty shiny Nice pics, thanks for sharing.

[77ChevySharkBite]

No problem man, there were a lot of good looking cars and trucks. They also had a mini swap meet but not very organized.

[77ChevySharkBite]

Alright guys so I'm back on the drawing boards again for rims, as y'all know I went to the autorama this past weekend well I saw a lot of these rims and I like how it was a mix of old school style but still had a semi new school to it. There called American Racing VN470 Salt Flats, I'm putting a link so y'all can see them. I want your guys opinions they are a fully custom rim so once there being made there's no turning back.

Man nice pics of some beautiful rides! I like the Salt Flat rims. Here is a picture I found...I think on this website (I really can't remember where I found it)
