Well Art thank you lucky stars...LOL...I could have put the wife in a Hunday!! <hell I cant even spell it....lol

 

thanks much for all the info everybody. looks like I have a 390 bored 60 over. (60 on the piston tops, 3.78 stroke) pistons look like new and the valves also are smooth with soft plyable seals but there was oil in the number 5 piston and valve cavity? pulled he piston and rings weren't cracked or stuck and no wear in the cylinder walls. remaning oil (oil was drained before I got it) looked like blown head gasket maybe? light brown. and drops of moisture in the lifters though the head gaskets looked o.k. I was troubled to find no valley pan under the intake. I thought the milky oil could have been form the previous owner trying to steam clean the engine but don't know about the oil in the lifters

 

according to the book i have in front of me, you have a 428cj block. part numbers and bore match up. the book also says to check inside the bolck behind the center freeze plug. 428 is cast inside.

 

"390 bore" 4.05 bore plus .060 equals 4.11 bore.... 428 bore is 4.13

 

although that is true, the casting numbers dont lie. and when dealing with .02" difference, its best left to the perfessional to measure.

 

He also wrote that the pistons show a 60 on them, which would indicate that they were 390 pistons + .060
I have seen casting numbers that do lie. Not to say that it is not a 428 block,,, It could be, but casting numbers are not always correct.

 

I have to agree with Lloyd here... a .060 ontop of the pistons..and a 3.780" stroke ..Its highly unlikely its a 428 block...unless it been de-bored and de-stroked.... Its a .060 over 390... Simple as that.... In my short period of on and off drag racing in 35 years ..i have yet to see someone take and de-bore a block..De-stroke yes..For higher RPM's.. but not bass-ackwards.. JMO...

with fe engines anything is possible. young kids were building these motors in the late 70s and early 80s doing all sorts of weird combinations because the parts were cheap and plentiful. its possilbe that 390 .060over pistons and crank could have been put in a 428block. i know of this goofy stuff because a friend of mine has a 360 truck motor with 428cj heads on it that his dad and my dad built in the 80s because they had the stuff just laying around.

 

The CJ head will fit but you have to notch the cylinder wall for valve clearance and that messes with air flow. Few would go grinding on the cylinder walls to make this work. Rather a waste of a good set of heads an top of that.

 

Casting numbers cannot be cross referenced to Ford part numbers.

Anyone that states a C7ME block is a 428 CJ doesn't know what they are talking about.

ALL 1965 and later 360/390/410 and 428 blocks were CAST as 352's.

Only when the blocks were finished could they be something else.

I've typed this a 1000 times here on FTE: Casting numbers on these blocks don't mean diddly-squat.

D2TE heads were used in 1972/74.

 

So ND would that mean that any block made after 65 will accept the 428s 4.13" Bore??? How bout the 4.16" overbore recommended for the 4.25" stroker crank to make a 462Cid???

 

Not necessarily...as I said...ONLY when the blocks were finished could they be something else.

You want a stock 462?

Go find yourself a 1966/67 Lincoln and pull that boat anchor of an engine out of it.

 

lol naa I'll pass but theres an aftermarket stroker kit for the FE that utilizes the 4.250" scat stroker cranks and a .030 overbored 428 or 4.160" Bore block to produce a 462 Stroker and if the end displacement and obre is all in he finishing I just kinda though you could take any one of the 352-260-390-410 blocks and bore them to 4.160"

 

Only a few of the high performance blocks can be bored past .060". I had an early 390 HP, 375 horse motor that I took out to 4.13 to make a 406 out off. But my 428 CJ I never took past .030" overbore.

 

I had one 428 CJ block that went to .060 and was thick enough to live there. Yes it was sonic mapped. I've had others that wouldn't take more than .030 due to coreshift.

To take Bills "352" comment a bit further. FE blocks were cast with 4 basic type of cyl wall cores and water jackets. First your 352-390s were one version. 2nd 406-428's were another that were thicker than the 390. Next was the thicker 427 of which some late 406's got the same cores. Last was the reinforced or Cloverleaf 427 wall cores. Note there have been some 406 blocks found with these cores as well. Those of you who know Dave Shoe from FE.com know well of his drill bit test. This is a simple field test that gaps the cyl wall cores with different size drill bits. To help tell blocks apart where the casting numbers or lack of fell short. Now like everything there are variations of use and timeframes between many of these. And I'm sure there are somethings that were tried in some of the race programs that don't apply. But when you lump them together as a group that's about what you get. This will apply to both FE and FT blocks. Short of a sonic map it's a very simple way to field check blocks. Granted there are a few select casting numbers that will tell you exactly what your looking at. But for the most part you need to dig into the block to see what you really have. As each one can be completely different from another.
