I can not find specs for 1956 F100 pickup with the 300 straight 6 motor.
Can somebody help me out?
I Need to adjust the long overdue valve clearance and set the timing.
I gapped the points at .020”.
 
its no wonder you cant as this engine came out in 65.if its original it should be a 223.points are .025 valves .020
 
A 300 six has a three grove crankshaft damper. A 240 looks the same but has one groove. I don't remember the 223, but I do remember they go like stink.
 
The original 223 will have two nuts holding on the valve cover on top of it. Later 6 cyls. will have small bolts around the gasket area of the valve cover.

This engine has eight bolts holding the valve cover but a single groove front pulley.
I find no tag anyplace on the engine.
I am familiar with the falcon engine and the 200. I ain’t one of them
I have owned and rebuilt a couple them.
I bought it as a 300, it has lots of power and is a real gas hog.
I just can’t find any specs even if it isn’t a 300.
 
I think I made a big mistake on the year.
I now believe it’s a ‘65 not ‘56.
When I got the motor it had an alternator, still has, the exhaust manifold was cracked, I took the manifolds from a ‘72 that I was junking out.
The previous owner of the ‘72 said it was a 240. So that would tell us it sure isn’t a 223.
 
Thanks Darrell.
I kinda figured it might have hydraulic lifters.
I set the timing to what seems to run best and start without kicking back on th starter.
 
Ok, I figured it out.
A ‘56 Ford takes a cartridge type oil filter.
Mine takes a spin on so it is not a ‘56 but a 65. It’s been a long time since the seller told me what year this engine is.
Thanks to everybody that helped straighten me out.
I have been running it in a ‘48 Nash Ambassador with an all synchro three speed out of an ecoline and a Jeep 3.08:1 rear end. Same wheel bolt pattern as the Nash.
 
not true with all as a spin on adapter was added to a lot.as mentioned some numbers would help to narrow down
 
Hi Aaron,

I replied to your message with some 240 six tune up specs I found (passenger car).
Should be close enough for truck too.

I thought of that too 54Vick, but this one does not have an oil filter adapter.
The oil filter screws on directly to the block.
I had a 1967 3/4 ton pickup with 300 engine some 40 years ago that I replaced a cracked piston in but I don’t remember any of the tune-up specks. I just remember how it pulled my 23 foot trailer house like it wasn’t even there.
I will go with what Sal posted and thank everybody that took time to post on this thread.
 
215/223/262 have the manifolds on the left (driver's) side while the 240/300 have the manifolds on the right side and distributor on the left (driver's) side.
