235 chevy engine

A friend of mine bought an old grain truck that had been setting for 20 years rebuilt the carb all new wheelcylnders and numerous other things to get it running. I noticed that the engine has no oil filter anywhere on it and the advance for the distributor actually turns the whole distributor when it has vacuum applied to it. I guess ive worked on alot of different engines over the years but have never seen one with out an oil filter on it anywhere. It is was before my time. Have any of you guys ever seen or worked on this engine.
 
the vacuum advance is correct.
the oil filter was usually mounted on the intake manifold behind carb. it was an add on and had hoses running from block to filter. it was a canister filter similar to the massey 44 filter canister.
 
Dave Iam from the old school the old filter was a option that bolted to intake manifold and was plumbed into the oiling system on the side of block below manifold also the distributor turning on advance with vaccum is correct any other needed just let me know as i have several old chevy service manuals thanks Larry
 
Pretty sure that engine also has babbit rod bearings with dippers on the rod caps for splash lube. Good luck, they're usually SHOT.
 
The 235 had insert brgs the 216 before it was a babbit beater. The oil filter was an option. I grew up with these motors. Big smile joe.
 
It runs perfect at an idle doesnt smoke had good compression. when going down the road it has good power in 1st and 2nd looses it in 3rd and nothing in 4th. I advanced the timing until it started hard then backed it off a little. There is no timing marks on the balancer or the front cover to set it with a light. The only other thing is that it possibly isnt getting enough fuel when going down the road. It is a very simple carbuerator and cant see anything wrong with it. It is not my truck it is a friend who bought it to haul firewood with and got in to a mess with it. Any ideas why it wont run when it gets under a load. The fuel pump seems to be working fine. Maybe make an adjustment to the float in the carbueraor. Any Ideas
 
How much horsepower and RPM's was the 235 rated for when it was new? Dad had a 1966 Chevy 3/4 ton with a 250cid six. That engine had less than 150 HP, maybe 140 or 125. That pickup was never a ball of fire. At the time many grain truck had the bigger 292cid sixes.
 
dave to set timing look at rear of engine there is hole in bell housing about 1 1/2 inches usually with a pointer in on passenger side turn off engine, then by handturn it and there is ball or timing mark on fywheel note this a white out marker or some thing you can see after starting engine run it as slow a possibe set timing with light to aline up with pointer then speed it up and see if it moves if it is alined and moves that is about all you can do like the other gentleman said this engine was not a ball of fire hope you can get tvman
 
all depends what u mean by wont run under load. with a load of grain on them and you wont get them out of first gear on field. like does it cut out , lack power or? have you checked the fuel pump flow? disconnect from carb and crank over engine should have good strong full flow into a jug or such thing. if it just coming out lazely then pump is at fault. lot of these also had the sediment bowl at carb inlet with a filter in them. others had inline filters installed. check that also.
 
You might want to check the valve clearances & look for stuck valves,I had this problem on mine.
I had a couple of bent pushrods.
 

You should be thankfull..you have a Power-house.!!

Our 1 Ton Chevy (1951) only had under 19,000 mi on it, Grain/Cattle bed and Single wheels (Slit-Rim)...Top speed, we never exceeded 50mph...
100 Bu of Soybeans up the East side from the river with all the run you could get from the Stop sign would yield 13 MPH at the top of the hill..Still in High gear..
Dropping a gear only meant you went slower...
Sure was a steady worker at low RPM...!!
If it rained, you had a choice..let the engine work and NOT see, or let up on the throttle and the Wipers would work a little..!!
But, the Heater worked good..IF you were lucky enough to be sitting in the middle..!!
Be HAPPY..you have a Power-House compared to ours..!!

The filter was an option and was piped to two quarter inch taps about an inch apart just above the oil pan in the block. It was a bypass type filter. Newer blocks had half inch taps and were full flow type filters.
 
not very many full flow filters before 1955. chevy v-8's w/full flow didnt come until 57 ford was about the same maybe a year or two earlier. Most had a bypass or partial filter. Some engines were a hold over like the 235 chevy, same engine from about 53 to 62 no need to upgrade just for filter . By the way they worked fine if you changed oil regularly.also I am thinking that the distributor like you described was only on the earlier engines like the splash oiled 216's paul
 
the 230 cid engine in the 1964 chev 1/2 ton's were the powerless ones , but sure easy on fuel. the 250 in my 67 gmc 1/2 ton with 4 speed was a good worker powerwise. the 292 in our 65 gmc 3/4 ton was a work horse and pig on fuel.
i dont have a bad thing to say about any of these old 6 cyl's. very good engines.
 
We have a 49 GMC that my Dad bought new, it has 65,000 miles on it. Has a GMC 228/4 speed, will pull a gravity box behind it to town in high gear and lug like crazy. It has the by-pass oil filter and the moving distributor like the Chev. If your using the 10% alcohol gas, you need to drill out the main jet in the carb 4 or 5 thousands, she will pull better, today's gas makes them run lean.
 
Really amazing how times have changed. We did a lot of work with those old sixes, slow, but a lot of work nonetheless. Now people think if you don't have 300+HP and 800 lb/ft of torque in a pickup truck you can't drive to town empty.
 
Rated around 100 HP the only trouble we had was lack of lubrication to the rocker arms and pushrod ends. They made a external oil line add on that lubed through the rocker cover, but oil is better nowdays
 

You want a 235 or a larger one..?

The 292 cu in has way more Grunt..

A friend (years ago) had a Chevy (GMC?) 261 in his '53 Chevy and got away claiming 216 for several years..(modified the valve cover)..
It had been known to beat a 348..!
Guy liked RPM...carried a big Mallet, so he could get the pieces of Blown flywheels out of the pavement..mostly from 283's and 350's..
