The date code should be where it's shown circled below. The code on this block is F 18 1:
F = June
19 = 19th day of the month
1 = year ending in 1.
You can tell this is a 1961 block because of the road draft tube hole (red arrow), there was no '51 Chevy V8, and the '71 didn't have the road draft hole.
Also it's not unheard of for the date code to be missing altogether. But usually there are enough clues to tell the exact date or darned close to it. In your case, different casting numbers were used during the run of 283 SBC engines, so between the casting number, the suffix code, the aforementioned side mounted motor mount bosses (or the lack of them), rope rear main seal used from 1955-'58, etc., can all help to determine the date it was made.

I have not messed with many of the early blocks. I may be wrong about the casting clock location. Its been on every chevy i have ever worked on but got to say i never ripped into an 57 engine.

|Jeepracer427||Ok thank you didn't know that. Guess someone put that intake on there at one time|
|11-19-2012 12:35 PM|
GF 1955 265 m/t, 3 spd, a/c - -
GF 1957 283 turglide FI car
GF 1965 283 Powerglide 195 2 full size
OK...If it is a 57 block it wont have the bosses for the side mounts.

|Jeepracer427||GF but there are 2 versions of the 283. the 2bbl one and the fi one. mine has a 4bbl intake that appears factory|

|poncho62||Is the suffix code there?...Its on the machined pad in front of the passenger side head.|

|Jeepracer427||I know this thread is old but I am having trouble finding my engine casting number. I've looked all over the driver side rear by the casting numbers but I can't find the year casting. It's a 283 but I'm not sure which one|

My first '67 I had back in the late-80's had a 194 6cyl, which I converted using a 283 from a 65 malibu. I knew I had to dump the cannister-type oil filter and get an adapter for a screw on filter. And since front-sump nova pans/oil-pump pickup parts weren't easily attainable, the only choice I had was a deep-sump early nova "notched" pan from Milodon...but the "ram" (power assist) and hoses had to be removed.
From what I understand, the recessed oil filter was made to clear the clutch cross-shaft/linkage as well. Never saw an original set-up personally, but attained a couple of 283-nova blocks over the years. They both came from automatic-novas, but had the pivot-ball holes for clutch linkage.
On another note, my last '67 nova was converted to 4sp. by the previous owner, using chevelle parts (and a typical SBC with a normal oil filter location). Actually worked good, with one exception...the clutch fork would hit the floor pan when pushing down on the clutch. He made a notch in the floor (just to the left of the gas pedal). Geometry must have been good...that was the softest pedal-pressure I've ever felt using a three-finger clutch. No herky-jerky feel in the pedal. The orignal early-nova bell housings had the clutch fork clocked-down to clear the floor pan.

Maybe it is a combo of both power steering slave clearance and clutch linkage clearance that the filter pad is recessed?? Anybody out there know for sure??
|05-28-2010 04:18 AM|
P.S. Early Nova blocks had a recessed oil filter to clear the power-assist. You could use a non-Nova block, with a shorter spin-on oil filter. But blocks with the old cannister filter can't be used...unless you use an adapter to convert to spin-on filters.

I also was looking for the chevy engine codes in order to get my problem fixed in my chevy which was bugging me for quite some time now.. found it lately. lets see if the chevy gives any further issues.

yah the early nova engines were like that so the oil filter could clear those chevy II chassies haha
unique blocks for those cars yeah
i totally forgot all about those til you said something haha
on a side note recently we had an old guy pull up in our shop drive with a really sharp mostly stock 64 or so chevy II nova and it had a warmed over 355 in it and it was pure bright white with all the stock trim and chrome pieces on it, and red vinyl interior that was mint condition spotless everywhere.,
the whole neighborhood was all over it checking it out
he wanted us to do a repair on one of the hood hinges.
he only gave like 1500 or some crazy sheep liek that for it and was one of those tightwads who manmages to find a steal by some crazy miracle but on purpose.
heard he sold it and now has a different old muscle car i forgot what now and got it for next to nothing as well

|cobalt327||Fast68, what was the deal with the oil filter boss being raised on Nova's? I seem to remember something along those lines...|
|04-03-2009 02:36 PM|
0717 is july 17th
need casting date off the block to determine year
is is on top ledge somewhere same as how the block casting raised numbers code is
last number is the the last digit of the year it was cast in
for example A129 will be jan 12 '59 '69 or '79 or '89, see
and i know that it is a 70-up block because it has a TKT three digit suffix stamping code
anything '69 older was only two digit such as the other person in this thead's FC code
