Interesting discovery inside 318

I just noticed the ridge line on top the cylinders, a quick hone job, and fresh rings will go along way to prevent an oil burner.

It's very very small. It's more discoloration in the photos than anything.

We're pretty much just looking at using this engine for a couple years to get it running and driving. Than building a stock magnum 360 with a mild hydraulic roller.

We don't want to sink to much into the 318 for that reason.
 
I hear what you are saying, going to build a cheap 318 just to get my next project car running.
Yes it will most likely have a bunch of parts I have laying around to get it moving.

My buddy tossed a rod on his 400 sbc dirt late model years ago...two weeks left in the season. Scored the cylinder. Fixed it by boring the hole time fit a Ford piston he picked from his junk pile... Bored the small end of the rod to fit the junk piston, picked the rings from a trash can then went out and won the feature two weeks later!

I've torn down Ford flatheads that had 3 steel pistons and 5 aluminum ones....

Exactly! Here's the deal... after watching cars being thrashed in the pits at the dragstrip in the dirt, NOTHING being torqued, nobody running air cleaners... I started to wonder if all this stress we put on ourselves trying to make everything clean and perfect even matters!
 
Uncle & cousin used to buy military surplus trucks and said mismatched was the rule there tear an engine down and find different bores and bearing sizes in it, only fix the minimum it needed.

We've given thought to throwing in a small summit cam and lifters with the limp factory valve springs just for the lope. Lol

Ha, pretty close to what I did with the motor I posted the pic of.
When we brought this car home it had a wiped lobe on what looked like a fairly fresh top end, and a severely plugged up carburetor. (not to mention the pump check ball out of it's seat and sitting in a pit where it was doing zero good)
The block never came out of the car, but it got a 1968 340 grind cam, new lifters, new roller set, oil pump and all new lower end bearings and seals, as well as knocking all the freeze plugs out, rinsing the block out and replacing the plugs with brass.
Oh, and a new muffler for the single exhaust.:D
Oh again, along with a full cooling and heating system flush.

(Snowball) :D

It runs and drives great now, for a 2 barrel 318.

I remember long ago when I worked at a dealership my brother was a mechanic also. A customer bought a new duster with a 318 engine and it came in with a misfire on # 7 cylinder he replaced the spark plug and it was fine for a couple thousand miles and came back with a misfire so he did a compression and cylinder leak test and found it was low and going past the piston. So he tore the engine down and found to his surprise no rings on the piston

That's special LOL... but how it would not use a quart of oil very 10-20 miles is beyond me. Maybe no top or 2nd ring?
 
I dont know but it was a new car may be tight enough clearance but it dident smoke and had no rings at all on the piston I seen it when he pulled it out of the engine. The car did not run rough until the plug would no longer fire then it came in with a misfire the second time when my brother tore the head and pan off to get the piston out. It had a little over 4 thousand miles on it
 
Interesting. I accidentally overlapped the ends of an oil ring expander on a new engine with fresh bores and new pistons once so that the oil scrapers had no tension on them.... burned a quart of oil in just 20 miles even with the top rings set properly.....but those were forged pistons with .004" piston-to-bore clearance. You just never know.....

Why not just buy a running 5.9 and drop her in as is or even do a ring and bearing job on that ?

That the same as the 300hp create engine and add a cam and you got the 380hp create or inbetween depending on cam.

We're looking at doing that down the road. We got this engine for $50. Lol. If for $350-$400 we can freshen it up I see it as a good cheap investment

But for $300-400 you can buy the engine you want running and drop it in as is.

Add a the cheap knock off airgap regrind the cam, headers and duels. And done. 360 + hp.

My 5.9 in my jeep has 250 km on it, I wouldn't think twice dropping it into something and hammer it away for the next 1/2 dozen summers and it it goes rebuild or find another $300 5.9

All of the cam bearings look beautiful except the 2nd one from the rear. What is that next to the parting line?

Make it smooth and leave it. The cam bearings have RELATIVELY low load. If the cam turns don't sweat it.

If you were going to run springs with 300 pounds on the seat and 800 over the nose I'd worry about it. For what you are doing, ignore it.
 
I remember a story in Hot Rod or Car Craft back in the mid 60s where the tore down a 273 that was original from the factory and found 10.5:1 pistons with the valve reliefs in the right bank and 8.8:1 flattops in the left bank straight from Ma Mopar...
