Is there some kind of resource be it catalog, manual, or diagram that shows all the hardware, type, size, and quantity on a 300 6 and its location?

If not can we create one?

 

There are differences between the carburetor 300 and the EFI 4.9
How do you want to break it down?

There is a listing of internal parts differences between 240/300/4.9 engines from 1965 to 1996.
Would that be of interest?

 

That would be of great interest.

I was thinking of things that bolt to the block so more of a depth diameter and thread pitch of those holes. But a complete list based on year and application would really be something. Kind of like the parts catalogs are setup I guess.

 

This represents the 1987 to 1996 EFI engine.

Wow! That was more than I was expecting. I can't wait to get home to the computer to study and save all that.

 

Here is a diagram common to the 1965 to 1984 300 engines.
The 1985 and 1986 engine is almost the same except it uses the pedestal mount rocker arms shown in the above EFI engine diagram.

 

Here is the 240/300/4.9 engine information.

Cylinder heads:
240 heads have a 68cc combustion chamber.
300 heads up to 1986 have a 76cc combustion chamber.
1987 and later heads have a 68cc heart shaped combustion chamber. These are the EFI heads

Heads up to 1984 have stud mount rocker arms with slot shaped pushrod holes in the head to act as pushrod guides.
Up to 1977 (unconfirmed) the 3/8" rocker studs used a 3/8 x 24 self locking adjusting nut.
The 1978 to 1984 heads use a shouldered 3/8 positive stop rocker stud with a 5/16" x 24 nut with no adjustment. The nut is torqued to the stud shoulder.

1985 and 1986 carburetor heads and 1987 and later EFI heads have pedestal mount rocker arms with round holes in the head for the pushrods.
1984 and earlier heads use a 4.810” long valve while the 1985 and later carb and EFI heads use a shorter 4.750” valve.
All have 11/32” valve stem diameter, 1.780" intake diameter and 1.559" exhaust diameter
SI valves is the main source for 240/300 valves that are the 4.750" and the 4.810" long stock lengths.

If the head is converted to screw-in rocker studs then the SBC 4.910” long valve can be used for oversize valve installation as well as the SI 4.810" long Ford 300 1.94"/1.60" valves.
The 1985 and later heads will need pushrod guide plates when converting from pedestal to stud mount rocker arms.
Chevy 250 six, Big Block Chevy, Ford 460 and Ford Cleveland 1.650" length rocker arms can be used with the screw-in studs.
Scorpion 1059 are 1.73 ratio pedestal mount roller rockers for the Ford 300 six. They are a direct bolt-on for the 1985 and later heads

Piston and connecting rods:
The 240 rod length is specified at 6.7947” and the 300 rod is 6.2097”. They are generally rounded up to 6.8" and 6.21"
The 1965-1968 240 and 300 rods have a .912” wrist pin diameter. 1969 and later rods have a .975” pin and an oil spit hole in the big end of the rod.
All rods are .992” wide at the big and small end.
Rod journals are 2.123”

240/300 block deck height is 10.00”
240 stroke is 3.18” and 300 stroke is 3.98”
Standard bore is 4.00" for all blocks.
Rotating assemblies will interchange between the 240 and 300 blocks.

A favorite combination is to use the longer 240 rod on the 300 crank.
This allows for a shorter and much lighter piston along with a higher rod length to stroke ratio.
The .912” pin rods allows the use of Ford 302 and 351W V8 pistons.
The .975” pin rods for 352 and 390 Ford FE V8 pistons.

The small 2.100” journal BBC rods have a .992” wide big end can be used with custom pistons.
These rods use the SBC 2.100" bearings.
The 300 crank rod journals are turned down form 2.123" to 2.100" to accommodates the BBC small journal rods.
The 6.385” long small journal BBC rod is available as an “off the shelf” item.

The 240/300 lifter is .875" and is common throughout the Ford six and V8 engine families.

The cam bearing housing bore on the Ford 300 engines manufactured after June 4th, 1985 was changed to make production installation quicker.
Previously all four housing bores measured 2.1440.
The late style block with the casting number E1TE-6015AA, has the following cam bearing housing bore dimensions:
Location Part # Bore Diameter
1 E5TZ-6261A 2.1590
2 E5TZ-6262A 2.1440
3 E5TZ-6262A 2.1440
4 E5TZ-6261A 2.1590

There are two main thrust bearings. A 3.567" OD flange and 3.602" OD bearing flange.

 

Here's a curveball for you. My 82 F100 has a 300 6 block that was cast in the second half of 1995

 

The 1987 to 1996 block had the boss for the fuel pump but the opening for the fuel pump arm was closed. It could be cut open if a pump needed to be installed.
What cylinder head does the engine have?

Is there any other information you would like?

 

If I remember right the casting number showed it to be a 300 head. I would have to go back through posts and pictures to confirm since I'm out of town. I figure the heads are original and they just replaced the block a few years back.

It'll probably take me a couple of days to get through everything you posted. You have over delivered lol if there's anything not covered I'll just ask about those things later, and thank you for all of the information.

 

I looked back through your posts and it appears that the head has the 5/16" threaded rocker studs and the slotted pushrod guides which dates the head between 1978 and 1984.
If the block used the 1996 EFI pistons the compression ratio will be around 8.3

Can you look at the top of the piston through the spark plug hole to see what shape the piston dish is?

 

I can't remember, need to check again. I have a cheap borescope. Last time I looked in there it was hard to make out much. I did ALMOST read the numbers off the face of the Piston but lost it and couldn't find it again. I plan to try again soon. I'm out of state for at least another week, maybe two. Will post what I find.

 

Haven't found my borescope yet, glancing in the plug hole the dish appears to be round, with something like 1/4 x 1/4 inch offset and depth. But it could be d shaped for all I know. Best I can do until I get the borescope out and hooked to the computer again.

 

The offset round dish piston was used from 1977 to 1986.
The compression ratio was around 8.7

 

What is the benefit of a higher compression ratio?
