Wondering if anyone can help ID the engine and transmission in my 61 F100? Its been swapped out with what the previous owner said was a 351W. The only casting numbers I can see on the block by the starter are 60150. The transmission has ford part number RF-E24P-7006-AA on the left side behind the bell housing. Any help is appreciated.

 

Pictures would be helpful. 6015 is a generic engineering number for block.

 

351W will have valve covers like so: /==\. Six bolts holding them on.

How many speeds for the transmission? Could be an AOD.

Check that number, could it be E2AP?

It's hard to get pictures of the numbers. The truck has headers on it which really make it hard to even see any numbers. Especially on the engine block. Posting a picture of the engine and the casting number on the transmission case. Could very well be E2AP instead of E24P. Had to take several pictures of the transmission case numbers to get the whole number. I would like to find the year the engine was made.

 

How many bolts in the transmission pan?

What does the shift quadrant look like--if it has one?

Can't read those easily.

Block casting date is near the starter. This video shows the numbers clear and will give you a better idea of what/where to look.

 

Awesome!! Thanks

 

We were looking at this picture earlier in a different thread and I commented I thought it looked narrow, like a 302, not a 351, which has a taller deck height and wider intake manifold. Here's some examples.





302




351W










To know what year the engine was cast, you'll need to find the casting and date codes cast into the block, behind the starter in one of two locations, depending on if it's 80's or newer or later. Early blocks were on the side of the block, later engines had their identification on a web closer to the bellhousing.

 

Your transmission pictures are too close up to get a visual identification on. Here's a spotters guide. With the side servo covers it makes me think it could be a C4.

 

I see what you mean about the intake being broader. From the diagrams I think the transmission is a C4.

 

Yep. 302, C4.

 

I took the starter off yesterday to see the block casting code. Its C90E-6015-O. I know that decodes to a 1969 block but thats it.

 

Some pictures after I washed the dust off.

 

I noticed in one of your pictures that whoever put that engine in connected the throttle linkage to the transmission kickdown lever on the carb (no idea how they got that to work) and there is no kickdown linkage going to the transmission. The best way to deal with an engine swap like yours is to go all aftermarket with the throttle and kickdown.

 

The C9OE block could have been used for several years. The important part is the date code just above it, which is partially obscured. It looks like it could read 8L29, which would read 1968, November 29th, making it a 69 302. Whatever the first number is, is the last number of the year cast.

 

I had not even noticed that. Its connected to the accelerator pedal so it works. lol
