As requested. Any idea what engine it is from looking at it?


cvphoto33789.jpg


The oil filter came off easily, it is a bit larger than the normal oil filter I am used to. Hope picture is good enough. It is hard to get a good shot of it.
 
what year is the C50,looks like a small block, 350 maybe, the oil filter is probably one for the 366 they will fit on a small block chevy
 
Valve cover and exhaust manifold says small block chevy.
Most likely a 350 which might be the original or one swapped in from who knows what.

Oil filter will not identify anything Chevy used the same filter base on 6 cylinders, small blocks and big blocks.
Diameters are the same but range from 4.5" to almost 8" long.
 
327 manifolds.dad bought 2 c 50 in 67 and air cleaner,ehxaust manifolds look same.but could been changed 350 manifolds you can see spark plugs 283 and 327 you couldnt see sparkplugs
Plus a truck engine had a bigger filter a canister filter in 67 about 4.5" across x 8 " long
 
Hard to say from that picture.

The double bypass hose on top of the pump is unusual, maybe from a larger truck instead of a car or light truck.

The ram horn exhausts were probably original to the truck.

The alternator on the left is stock to the truck.

Rubber oil cap and PCV say late 60's to '86.

If original orange paint, it's pre '78.

I'm guessing a 307 or 350.
 
Most of them had a 350 . was it a van truck originally ? lot of them sold around here when the company sold out they were green I think ez haul . 1967 to 1972
 
Thats a 72. Less than 30K on the odometer. Tom says that is the original miles, the seats are like new so inclined to believe him.
 
Agree with rwb that it could be a 327. As you may know, Dave,small block Chev engines like yours are for the most part identical externally...from a 265 to a 400 they Do look much alike with some small differences depending on the year of manufacture. The should be a smooth machined surface on the front of the block with some stamped numbers. This number/letter combination will give you the engine code which from then can be determined the engine designation, which will tell you it's displacement, carburation, compression ratio and application.....given the age of the truck, the engine could have been replaced at one time, and without the code, it's anybody's guess to its origin. Good hunting!

Isn't there a decal on either the side of the air cleaner or the top of the radiator with the engine size and tune up specs.?
 
Could be a 283 if it came from an older vehicle. Most had the old canister oil filer. The 350 engines had a spin on.
 
The 366 and 427 engines could have a 4 barrel holy carb. Also look in the glove box for a build sheet with a lot of letters and numbers in combination of three?s. These are the regular production options (pro). Look for rpo?s in the L?s. There is a list on line if I can find again or call a dealer. Hope this may help. Tim
 
these are the engine options for the 1972 C60 . Several engines were available: 250 Six rated at 100 hp, 292 Six at 130 hp, 350 V8 at 160 hp, 366 V8 at 200 hp and 427 V8 at 230 hp. Since 1977, the four cylinder Detroit Diesel 4-53 was available.
 
Being a 1972 with the original engine my vote is its a 350. I do believe the options were 292 six or a 350 or a 366 for the C50 truck in 72. My job during that period was working at the local power company doing the pms on their trucks. Most of the C50s we had were the 292 six and the C 60s we had were 366s. Our 366s had a wider valve covers than what your truck has.
 
Chevy made several motors in 1972 but they only put 5 of them in trucks.

250 and 292 were inline 6 cylinders.
402 was the big block. Same thing as the older 396.

Then there were two small block V8's The 307 and the 350.
The only way to know for sure if it is a 350 or 307 is to get the casting number or engine vin number.
I posted pictures of where these numbers are in your last post about this motor.

I can't believe the bla bla bla in this thread. It's NOT a diesel, it's not an "in-line six", and it's NOT a "big block".

As I wrote before, it's a GEN 1 small bock Chevy, could be a 283, a 307 or a 350 (etc.) and which SBC it is matters not one whit unless you are ordering internal engine parts, the waterpump and all basic external accessories interchange.

And the raised t-stat housing and bypass hoses are perfectly consistent with a Chevy "medium" truck with a sbc engine in that era.

It would be interesting if the O.P. had paid any attention to the replies to his previous post and looked for and posted the engine block casting number at the LH rear of the block, and the info from the engine number stamped area at the RH front area of the block.

Ditto!!
It's amazing how these threads go off the rails.

Geez Bob, relax before you do yourself an injury! I heard you before! Thing is, I'm not currently physically able to get back in there and look for the number. The engine is very dirty also so it would take a little time to clean and locate that number. This is not a Mustang, I cannot just lean over the side and take a peak. It's shoulder high and I'm no kid anymore. Cut me a little slack, will ya?
 
Bless you! That is all the info I need and I will make a note of it.

For those who are unaware, Tom is the original owner of this truck and sold it to me a few years back. In fact, it is affectionately known around here as "Tom O'Connor's truck".

You are right, Tom. It was actually pretty easy to get the water pump and the oil filter was on Amazon. After tomorrow I should have it back on the road and doing what it always does in August...haul sand and gravel for the concrete I am pouring in the shed or just plain gravel for the lanes. Appreciate you weighing in, hope all is well with you and yours!

Sorry to have troubled you.

The information you need to put this to rest is on the engine, available to you, and not to any one else viewing this thread.

Likely, at some point you will break down and have a take a look at it and your curiosity will be laid to rest.

In the meantime, by all means, keep up
the posts asking everyone else to GUESS, and you may rest assured I won't trouble you any further.
