engine code info

[Docweld]

Hi, I am new here and have a question. I picked up a 1974 FJ40 last summer and it came with a hole rusted out 1977 for parts. The engine was not in it but I have it. Now my 1974 should have a F code engine and it has a 3 speed tranny, I would think the other engine would be a 2F engine but the stamp on the engine is F-330835. I do not see a "2" in it but it is much different from the engine in the 1974. Can anyone tell me what this engine is so I can look into rebuilding it to install it?
Thanks
Docweld

if they're is no 2, it's probably a '70 or '71 F.
what's the production date of the '74? only a few of early 74s had the 3 speeds.

 

[Docweld]

Jan 1974.
so why is this spare engine so different from the one in the 1974?

 

[brian]

pictures would be a big help also.

 

[Docweld]

ok, let me see if I can figure out how to post some.

 

[Docweld]

pics of both

 

[brian]

top one is an F
bottom is the F.5 for the 74.

 

[Docweld]

witch one is the better one? The one in the running 74 seems to loss oil pressure after it warms up as per the gage. also I want to swop out the 4 speed out of the 77 but it has an extra leaver on the tranny/transfur on it, have you ever seen that? shifter,2/4 wheel shifter and an extra one.

I dont see a four speed transmission...

 

[Docweld]

I have not pulled it out of the 77 parts one. I may be able to take a pic of the extra lever if that would help?

 

[brian]

the trans on the F is a 3spd with the column shift top plate and some linkage still on it.
the transfer was originally vacuum shifted from 2H and 4H.

 

[brian]

if there is no engine in the 77, it would be hard to have the trans still in.


i would check the oil pressure in the F.5 before fully trusting an old pressure sending is telling you the truth.

 

[Docweld]

Well, I feel like an idiot now. right before you said that I figured that out. how could there be a tranny on this engine out of it but a tranny still in it...... Thanks
so the engine in the running 74 is the f.5 and a better engine so I should just fix the oil pressure issue but what about the extra shifter lever in the 77?

picture of lever in question.

tranny in the 77

77 parts tranny with 3 levers

 

[brian]

Don't think that is toyota stuff

 

[Docweld]

I think he said there was a chevy 305 in it but he pulled it to keep the motor

 

[Docweld]

How can I tell a 3 speed from a 4 speed? this is also and extra part I got.

 

[brian]

count the gears.

thats a 3spd
