Nick rebuilt the 440 Six Barrel for this beautiful 1970 ‘Cuda, but once he got it back in the car, a noise has started coming from the engine. Today, Nick will try and track down the issue so he can deliver another dream car.

Awesome job Nick
sounds like a sloppy big end on cylinder 3
All that power, in a small car, amazing
Nick is the rocker shaft a harder material than the rocker itself? I’m curious if the rocker is designed to wear before the shaft?
Is that a factory spec. cam ? In my mind that answers some questions the way she kicks down and the out board carbs open .
im runnin adustable push rods on mine
ek2 tored orange really catches the sun
"Got a noise in the engine"
It's a Plymouth, what did you expect?
Unsettling noise? Sounds horrible!
i heard it and i thought ohh no another flat cam you definitely got blessed there nick
Yeah it sounds like a valvetrain issue to me but it's really hard to hear over a video gotta get the wooden broom stick out and listen inside the engine to where it's coming from
Got er running great Nick. Good job as always!!
The 440 six pack is tuned to perfection I’ve never seen a 440 six pack with a automatic transmission that leaves hard as it should. Awesome Nick.
took a while to quiet down after the first start up why was that?
If that's a true 440-6 engine that valve train's special for that motor. A regular 440 rocker arm won't last. The cam, lifters, all of it was different than the regular 440. Even the fuel pump. Doubt it, look it up in a period parts book.
AWESOME COAT HANGER !!
it will make a mamie huncher grin.
Happy memorial day glad that everything is going smooth. I don't know if anyone has noticed or mentioned this to you. The microphones you guys are using are very sensitive and pickup a lot of unnecessary noise. Can you add more noise protection on the microphones to help make them a little less sensitive to the environmental noise around them. I only mention this to help no disrespect intended in anyway.
When I was a kid we used to always build 440s and 383s. Usually a junkyard motor we bought for a hundred bucks. They really benefit from a windage tray. Especially if you're spinning donuts and figure eights. The oil gets frothy and you spin bearings. So don't spin too many donuts in a row. It's easy to over tach too, and you float lifters and bend pushrods which is hard on rockers, springs and keepers. You learn to respect machinery if you have to fix it. Treat it with respect.
Well that was planned antiseptic at its finest.
Nick is a Badass. Period.
Has a bog when the 6 packs opens up. Engine shakes to much at idle. Something else is wrong like a lifter eating a can lobe. Time will tell. I have never seen a tick go away with the way the stock rocker arm looked. Nothing looked wrong with the stock rocker arm than the other one he put on. Of course we did not see were the pushrod sat in the rocker. I have seen when the pushrod breaks the rocker arm at were the pushrod goes into the rocker arm. No way you gona miss that unless you are blind.
Mopar tin rockers,, try them on the shaft and see how oval the hole is. Then check the tips for being flat. And the pushrod cup for wear. Then throw half of them intothe scrap pile!!
Normally I dont like chrome bumper cars with the bars painted, that one though looks trick. The only Mopar I would buy, Cuda or Challenger of that generation. Small block car though to make it handle ok
Typical Mopar though with 2 sides to a front tyre
I was sure that was going to be a worn cam lobe. I don't understand. The old rocker looked the same as the one you put in. I've taken rockers out of running but high mileage engines that had the hole for the shaft in them elongated oval about 3/8 of an inch and they weren't making noise. Presumably the lifter pumped up enough to take up the slack as it wore.
What was wrong with the old rocker??
PS, I've even seen small block rocker installed on a big block head… not all of them, just one. I think I even saw "left" and "right" rockers in the wrong places. And still no noise.
Shimming works OK. But: Is it really necessary with hydraulic lifters? Also, why would anyone deck a block or mill heads to raise compression? It causes a cascade of problems while compression can be set to whatever you want for engines like these because there are plenty off off the shelf pistons and custom pistons are cheaper than compensation for the mismatches that result from milling heads and blocks.
I don't think I would mill a block even to make it square. The machine shop guy that says it isn't square is just as likely to be wrong and cut it and them make crooked as he is to correct it.
factory knock wait till it builds oil pressure
1970 , same year of the Cuda and Challenger I was working part time at a Shell Station on Rte. 22 in N.J.. We used to get Chargers , Challengers and a Cuda in for a fill up. I miss my Newport , had to sell it last year due to health problems.
Why you checking the timing…that ain't it.
Nick is just a fine wine. I just like to way he just methodically diagnosis a problem with patience and uses the many years of knowledge he ha attained over the years to tackle a problem. He just lives and breathes cars. Just one of the great engine builders . Thank you Nick for sharing your knowledge with us .
Also great job to the entire crew at Nicks Shop.
I have had the cam bearing that feeds oil to the top end turn a little bit and block the oil to the lifters and they will tick from experience it happened to me but I found it and fixed it lesson learned!
Nick we always want perfection instantly… we are human and sometimes takes a little more effort to reach perfection.
Retired Driveabilty Mechanic. If you had killed each cylinder. You would have found out when taking off number 4 cylinder spark plug wire. The ticking would have gone away because u unloaded the cylinder.
This guy can't see/hear/feel an obvious cylinder misfire, either on the dyno or in a car he's even driving. It seems his builds run on luck.
