I bypassed the heater core and no longer any smoke. Trucks running and driving pretty good. Need to find a muffler and a tailpipe section for the exhaust. Excited to take it to some car shows this summer even though it's the farthest thing from a show piece. Not many people have fully built their own motor and especially built a wooden flatbed for a truck lol. I bought it from a old man who only drives these trucks and he loves what I've done with it.

Been attempting to diagnose a slight ticking sound somewhere. I believe it's a exhaust leak where I'm missing a bolt. It seems to go away when it revs and is noticeable during idle.. I was just double checking the pushrods and lifters.. it runs fantastic. No cutting out or anything. Anyone see anything odd here or am I good to go? There's a ton of oil. You can hear the slight tick out of the back of the exhaust too..

I think I am just worrying too much about it. It runs and drives damn good with no cutting out.. so if it's going to fail it's going to fail at this point. I'd rather an exhaust leak than a lifter though, lol.. I don't hear anything super worrying it's just noticeable at idle. I guess I can't expect it to be silent.

I haven't been around enough FE engines with the valve covers off while running, but I would be concerned about lack of oil. When you rev'd the engine, I think you should see oil spraying out the pushrod quite a bit more. SBC for example, if you rev'd the engine like that while adjusting the rockers you'll end up with oil on the hood, exhaust manifold, inner fender, etc. Even without revving it still makes quite the mess. I know that is a different engine all together with adjustable rockers rather than the non-adjustable shaft rockers on the FE engines. Perhaps someone with experience on the FE engines can chime in.
Here's a short clip I found of a 428 Ford and it appears he has a lot more oil flowing, but maybe it's just due to the different perspective from the side rather than the top.
The wire that blocks the clear view of what I think is #5 intake rocker, might be playing tricks on my eyes, but that one didn't seem to be rocking as much. Hard to say though with the wire being there.
Are all the pushrods spinning? Might need to wipe some oil off and use a paint marker so it is easier to tell when it's running.

I may just seal it back up and not worry about it if it doesn't cause issues. I think i overthink stuff
it'll idle at 40 psi of oil pressure, i know that doesn't mean its coming up to the rockers, but still.

Sounded similar to me too, there will always be a little bit of noise in the valvetrain.

Yeah. The FE has one special bolt on each side that goes into the oil hole on each head (forgot which numbers) but it allows oil to come up to the rockers and that's how they are oiled. I tripled checked that they were in the right spot and I went thru my rockers. (Feel free to correct me if anything I said was non sense, lol.)

Encountered my first real issue. Started the truck up one morning and it ran good. It slowly started to miss and now barely runs. I thought that was weird, I have had to mess with the points multiple times as they close up. I have good spark
So, i thought it was flooding out. I completely closed both mixture screws on my carb and I was under the impression it shouldn't run at all, but fuel still drips in and it runs the same, is that normal?
(popped the valve covers off, everything still normal in there)

If you can seat your mixture screws and it doesn't stall or at least try to stall, I suspect vacuum leak. Have you re-torqued intake bolts and snugged up the carb base bolts now that you've driven it and heat cycled it a few times?
If you can see fuel dripping from the venturis in the carb, you might have a float and/or needle seat issue. What are you running for a carb?

i haven't retorqued any bolts. Ill do that. And i just dont think i had my points set correctly / i had to replace them. My distributor is a little rough, actually, the condenser is unable to be removed. Bolt isnt stripped ive gotten the biggest flathead i can and it won't budge. I'll have to keep trouble shooting. I haven't had time to diagnose, been working on my Bumpside.
