Is that a casting number or a stamped number because ford casting numbers usually start with a C for 60's D for 70's E for 80's and F for 90's.

The number you give with the 6015-A in it is a part, or engineering number. It should read either C8OE, or D8OE. Check it carefully, and if you see the C then it's a '68 or later number, if it's a D then it's a '78 or later number. Those numbers I take it are cast numbers. The other number you gave, 7F5 is a date code, also cast(?). That number would be either 7='67 F=June 5=day of month. Or it could be '77 June 5. Thats the parts casting date. BTW, what part was that 6015 number on? I'm lost on what part that is exactly. If it's got '68 part numbers then you are probably looking at either a 302 or 351. The best thing to do is try to check the cast numbers on the block by the starter. That'll help narrow down the block. Also, if it has a stock intake manifold, what is the firing order. There is no way on the engine to tell what car it came from, only the year, and sometimes assembly plant. Long post, sorry, but hopefully you'll find some of this info helpful.

If it's a 302 the firing order will be 1-5-4-2-6-3-7-8 counter clock wise and if it's a 351w or 400 the firing order will be 1-3-7-2-6-5-4-8 also counter clock wise.

after taking off the starter again and scrubbing away some built up dirt the first letter was not a "o" but a "c" i looked in some ford books and it says it is one of the first 302 blocks. but many of these engines produced at this time were still 289 ci. so i still dont know what i have??

does the firing order differ from the 289 to the 302?

thanks for the help. RC

The following information is from the Ford Y-Block Site (www.ford-y-block.com/fordpartnumbers.htm) and others including: (68.48.48.131/~djhamma/partnumb.htm#Ford), (www.wantabe.com/hdrace/dfrdpt.htm), and (www.geocities.com/MotorCity/Downs/5505/castings.htm). Some of the information in the various web pages conflicts but I think the following is the correct interpretation.

Engineering (on the part) part number C80E-6015-A

C - Decade code - C = 1960 decade was the first decade for this part
8 - Year code - 8 = 1968 was the first year for this part
O - Application code - O = Intermediate sedan - Fairlane, Torino
E - Part category code - E = Engine part
6015 - Part identifier - 6015 = Engine block
A - Sequential design revision - A = First release

Date Code 7F5W

7 - Year code - 7 = 1977 or 1987 or 1997
F - Month code - F = June
5W - Should be a two-digit number to indicate the day of month. E.g., 05 - fifth day of month, 22 - 22nd day of month, etc. Have also seen references that indicate the single digit 5 is the fifth day and the W is the shift. One reference indicates the W might be for Windsor, as in 351 Windsor.

Does someone have some definitive physical differences between the 289, 302, and 351? Things like "the dipstick on the 351 is on the left and it's on the right on the 302 and 289".

[updated:LAST EDITED ON 03-Jun-02 AT 11:27 PM (EST)]That date code would be most likely a '67 casting date since the block is a '60's number. ID'ing the differences would be kind of tough since the 351 is merely a stroked 302. The main thing is that the 351 is about 1/2" wider than the 289-302, due to the stroke being longer, Ford raised the deck on the 351. This would mean a new block, a block that should carry a C9 number since it's a new casting for the '69 model year. Other than that they look nearly identical. I have a 351W in my '70 Mustang, a 289 in my bro's '66 Mustang, and a '68 302 that I'm getting ready to drop in my '46, and they all look the same. The 'O' does mean Fairlane, Torino line, however, that letter is on most all engine parts that came in passenger Fords at that time. The firing order of the 289 and 302 is the same, the 351 was different to relieve stress placed on the crank. It sounds like the engine in question is most likely a 302, it could be a 289, but not as likely. Most all parts will interchange between 289 and 302. If you really need to know, then pull a valve cover and on the head, between the valve springs, look for a 289 or 302, and you'll also see if it says 2V or 4V, for the number of barrels on the original carb.

Thanks for the help guys. your answers do clear things up for me.

the only thing that still is unclear to me is the "7f5w" date code stamped on the front of the block. i cleaned the it off real good and it is definately "7f5w" i understand the 7f5 but the w makes no sense. my dad said the w usually related to windsor also but i guess not in this case. maybe someone just screwed up?

thanks again guys. i would be banging my head on the concrete if not for this web site. RC

The block was cast in the 60's but was assembled in the 70's, the W is the employee who assembled that motor in the event that if something was faulty with that motor they would know who assembled it. The 289 and 302 are the same motor they have the same bore and stroke, all they did was extend the cylinder walls downward a little on the 302. The only differance were the heads the early ones had small CC chambers then in 72 they went big.

uh, if they have the same bore and the same stroke then the ci would be the same yes?
the stroke on the 302 has to be a little longer by about .020ish doesnt it? RC

No, when I rebuilt my 72 302 I bought 10.5 to 1 TRW pistons and they had the same casting numbers as the 289. Some people may think the 460 has a bigger bore than the 429, wrong they both have the same bore but different stroke, you can take that to the bank.

The only thing i'm not sure of is,if the size of the journals are the same on the 289 as they are on the 302 because on the 289's and early 302's they had 28 oz. balancers and in the 70's they went to 50 oz.

The 302 block does have longer cylinders, but that was done to accomodate the longer stroke of the 302. If the bore and stroke was the same then the CID would also be the same. The bore of both the 289 and 302 is 4.00". The stroke of the 289 is 2.870, while the 302 had a stroke of 3.00. So, to get 302 CID Ford just stroked the 289 and lengthened the cylinder.

What is the firing order for a 429/460 about 72'?
