Ain't that the truth all around! Last 10% takes 90% of the time.Nice, these little updates/fixes make a rig so much more enjoyable.
Getting the rig from 90% to 100% takes the most time
That's never a fun ending to a cruise!!Two steps forward 3 steps back
Had time to tackle the brake switch yesterday, welded a new stop plate for the button to the pedal to i could use an existing tab mount i had and then welded that to the pedal mount. All turned out pretty sweet, rock solid, and the switch engagement and feel are sooooo much better. Actually works like a brake switch should.
Took is for a cruise with the wife and kid, on the way down i kept hearing this mechanical rotational ugliness. But it went away at idle/low rpm. Almost sounded like top end knocking but not metallically enough if that makes sense. Got the lake and the rig is running warm, which is odd as the ambient temp is 20-30 degrees lower than when i did all the fan testing.
Made it 3/4 back and its screaming at us, wife just keeps giving me that look of "you broke it again", I'm beside myself as its been running great, glance at the temp gauge and its 250 before i get a chance to pull off the road, the truck starts pulling RPM, like brake drag pulling, and poof! Coolant everywhere.
99% sure my water pump decided to permanently attach itself to the housing somehow they're both aluminum and the clearances are tight. The truck starts fine and moves, the pulley is turning on the outside but temps just climb immediately.
Fortunately I'm a Mopar hoarder and have a spare passenger outlet housing and water pump sitting on the shelf, do some investigating tonight and see if that's the culprit.
Well i am indeed a certified glue eater.
Found some time to get the pump housing off, i wanted to just pull the pump but with the fans that wasn't going to happen, have to pull the alternator and hydro pump to get the housing off.
Turned out i have (3) water pumps and housings, two passenger outlet housings and one drivers and 3 different pumps. The pump that was in it was stated as a high flow but ill be honest, it looks like the factor impeller style. The pump i previously has on it is anodized blue and has a totally different impeller design, so i opted for that one.
Reused the gaskets and slammed it all back together, filled it up, and it starts streaming from behind the passenger outlet. Gasket was not good i guess I knew better.....
Ripped it all back off, healthy amounts of RTV applied, and decided id let it sit overnight to set. Hopefully fill it up tonight and the rotational ticking goes away.... the water pump spun freely which was not what i was hoping, but there no chance it was circulating water by the water temp rise i got at idle once i dragged it home.
I checked with the builder of the destined powerplant for this thing and the short block is together so were closing in on dyno time, but I'm about over the big block in this thing. I just can't seem to keep them alive. I think its a combination of the less than stellar oiling of BBMs and that they run hot. This block still is kicking 45-50psi at idle though.....
If this block dies this will be the 3rd 440 combo the truck has killed.....
Still ain't going to LS it
Make the ECU stop you.Agreed with what was said above.
Hellcat or keep the big block but in all reality if you have the proper parameters set in some modern ecu for the big block it should be happy if you stop when the big red flashing lights are shining at you through the little ecu screen
Don't be an idiot.
Install a good inline electric water pump. (Edit: by good I don't mean a direct mount Meziere)
Install a good ECU with modern fueling and ignition. (edit2: by good I mean at the very least something that has sequential capabilities)
Edit: AND GET THAT SHIT TUNED PROPERLY !
Keep the Big Block.
If you want to be lame get a Hellcat / TRX dropout.
(If you want 8hp support that interfaces with a Holley ECU, I know the guy to talk to)
That's not how tuning works.I haven't even driven it enough to tune it, one Fordyce trip to WH1 and back and some jaunts around the property,
You'll be fine, the blower doesn't give 2 fucks.I looked at the hellcat drop out really really hard before commissioning the new big block, it ended up coming down to the fact i don't think id keep the supercharger alive in the conditions im in.
It's just moneyI couldn't get my hands on a 8hp95 for a decent price.

I'm not going to beat you up for it, but you "didn't care" about this engine, and you're dealing with problems that are unfortunately expected to happen in your situation.
Putting money in a good tuning session (at the very least) will avoid aggravation and time spent on the side of the trail/road. It's worth it. Even with a $500 engine.
Don't you give me hope on the blower surviving. That was the cornerstone of my fragile argument to keep it n/a
Fine fine, ill find a local tuner. I don't disagree with any of your points, they're all valid and true. and it'll be a good vetting process for when the intended powerplant shows up.
That's great news !Onto better news the water pump was 100% the culprit of the overheating. The one i swapped in is flowing way more at idle, the fans actually cycle and it takes significantly longer to get from the 165 thermostat opening to the 185 degree fan trigger. depending on the ambient temperature it didn't actually push over 180 mark.
Good outlook on things.
And if your tuner is more familiar with another system than the one I've been talking about here (Holley), and said system isn't a giant POS (like FiTech or Aces), then go with his suggested solution. It helps having a good tuner in your pocket.
Hydraulic rockers?I'm getting an awful ticking/rattling under load that sounds topend. Not present at idle at all, not present revving at idle, only present underload accelerating at 2500rpms+
Hydraulic rockers?
How often do you check valve lash ?flat tappet, no lifters to collapse.
I feel like a bent pushrod would be constant tapping, and broken/cracked flex plate should be making noise at idle in park/neutral and go away under load.
She runs good, like burnouts in 3rd gear good. Its definitely heat related, as it gets louder the longer i drive it. The specific scenario its deafening in is cruising uphill in 4/5th at 40-50% throttle.
How often do you check valve lash ?
Do that and change the oil / cut the filter open.
Dude.did you just ask if i checked the valve lash in a 500 dollar facebook marketplace long block?
Dude.
You can't "not give a fuck about the $500 fbmp block" and at the same time wonder why it doesn't run right.
Go check the valve lash as well, it plays into tuning.
And by once over, we mean checking pushrod straightness and lashing the valves.I agree it needs a once over of the valvetrain and intend to do so, pretty sure the valve covers is ever so slightly leaking on the #8 tube as well so it would be nice to regasket it as well.
And by once over, we mean checking pushrod straightness and lashing the valves.
Maybe $12 valve cover gaskets if we want to be fancy.
Not throwing the comp cam kitchen sink at it.
Easy way to see if that tight rocker is the rocker or the shaft is to swap another rocker in its place and see if it’s tight too. You could also see if the tight rocker is still tight in another spot on the shaft.
Travis..
flywheel to crank bolts?
this is what it sounds like when they are all finger tight...
The plugs looked really good to be predetonation and didnt sound like that to meNot pinging, like predetonation?
Since it is under load, that’s what I’m thinking.
Make sure there isn’t a zip tie around the drive shaft.
Could be a head gasket, but the coolant isnt showing signs of compression in it and the oil didnt look to have a bunch of carbon. But it could. If thats the case the old block is going to show me that problem before i tear it downAt this point your pretty close to doing head gaskets anyhow. Maybe small tear that is getting combustion gases into oil passage?
The problem starting under load almost sounds like a cam lobe going bad but if you already checked that I dunno. Weak valve spring maybe? gets warm and starts losing valve control.
Sorry if you already covered this but do you have a A\F Gauge in truck to know what the FI system is doing for lean\rich under that 2500 load condition?
