I will give the ATF a try. I can't figure out why, but the kid wants to see the smoke. The Knocking started all at once which is why the mechanic thought maybe carbon. I did have to take the intake manifold off when I purchased the truck to clean out the carbon, so I am hoping this will solve it. Thanks for the help. I will do it Saturday and let you know how it works out.

We were thinking about a JY engine, but I don't know if I would recognize one that is worth redoing. Noah, my son, also keeps telling me we need a 440!
you should give the boy what he wants so he wont get rice fever.
is it lifter tapping or lifters rattling??
sound like something banging around in a cyl?
idle smooth or run ruff?
is it cold there right now? how thick is the oil cold start up?
what kinda oil pressure?
knocking comes from down low not up top. IMO
a cheap JY engine is a good start for the first time. just tear it down and inspect everything then put it back together.
I have pulled a lot of used engines apart then do a valve job, re-ring/bearings for the bottom end,oil pump,core plugs,gaskets.
change the cam and home port the heads then add bolt ons.
done it many times under 600 bux and have had more fun with less.
want smoke??? follow the directions on the can of seafoam.
ATF added in with the gas,will lube the upper cyl,cut down on sparknock,smokes a little.
but it will also get a build up of ash/carbon on the cyl head combustion chamber. it will also build up on the plugs.
best to use water to decarbon it,use a spary bottle on mist and spary the heck out of it at idle only rev it if it stumbles. that will steam clean the cyls.
to much of any solid liquid will hydro lock it so go slow adding it in.
I like seafoam or the BG upper cyl lube or mopar upper cyl lube/cleaner.

If you want a sweet junkyard engine, go to the yard, look for a maroon or dark blue or silver Fifth Avenue with the half-vinyl padded roof, '86-89. Find one with a really nice interior. Pull the engine and take it home. Leave the intake manifold and two-barrel at the yard.
Degrease engine, take it apart. Number everything because you're going to reuse most of what you find. Here's what you should find: 0. Roller 318 block with next to zero wear in the cylinders. 1. 302 heads. 2. Flattop pistons with no signs of excessive wear. 3. 645 connecting rods, they started out as a 340/360 forging and are quite strong. 4. Cast crank in perfect shape. 5. Hydraulic roller cam
Send the cam to Bullet for their 259/316 grind on both lobes, that's Patrick's favorite grind for this job, should set you back less than $150.
Disassemble heads, keep everything in order.
Read Steve Dulcich's article on porting the 302s. Forget putting in bigger valves, just work on the ports. Don't do a valve job until after!!!!
Reassemble engine with good parts, I am using Crane 833 springs, Patrick has a couple of other favorites, the Comp 901s being mentioned a lot. You should probably cut the valve guides down at the same time, stock stem seals are 0.625, valve stem size is 3/8, so you need a 0.625" cutter on a 3/8" pilot. I got the cutter from the 'bay for $50. I did mine with my Milwaukee drill. Now you have retainer-to-seal clearance.
Put it all together and stick the intake of your choice on top. Mine is a 1976 or so 360 cast iron spreadbore intake and I'm going to use a Quadrajet because Scratchin told me to, also because I want MPG! Add a distributor with a decent curve in it, a set of headers or good manifolds and you're looking at an honest 250 hp, maybe more, that will be able to drive past a gas station.

Your kid may want a 440 but a nice 318 will allow him to actually afford to drive the vehicle.

The Seafoam is designed to do what you need. It will provide the smoke you son wants to see but will work much better that the ATF.
I am truckless..

might try removeing all 8 spark plugs and roll each piston to the top with valves close and sux it out with a shop vac.
might blow it out the plug hole with compressed air thru the hole as well.
You don't wanna use a shop vac to suck anything out, you'll just suck all that dust/dirt around the plugs right into your cylinders, law of physics there! Compressed air is the way to go!
