440 is a"RB" or big block and the distributor sets in the front and a 360 is a small block and the distributor sets in the back.That is the easiest and quickest way to tell.

A tougher question is how you determine the difference between a 440 and a 383.

a 440 has a raised stamp pad in front of the block(to the right of the distributor, basically under where the air compressor would go. a 383 does not have that pad in front top. that's the easiest way to tell by far

Excuse the poor photo quality, but you get the idea. An HP block will have HP stamped on this pad.

Be mindful of the fact that 413 and 426 wedge engines have the same pad as the 440. Don't assume just because it has the pad it is a 440. Not so. The 'B' engines (383 & 400) also have an ID pad. It is located in front of the head at an angle. The nice thing is that the cubic inch of the motor is stamped on these pads. So, it is easy to tell exactly what motor you have by a glance. These pads will tell you the date of the engine and whether it is a high performance 'HP' motor or not. The date code will be represented by a letter though. For instance, a 1969 440 Magnum engine would be stamped E 440 HP. A 1968 440 Magnum would be stamped D 440 HP, etc.

B = 1966
C = 1967
D = 1968
E = 1969
F = 1970
and so on....

413 engines are fairly common motorhome and other utility engines, Bugsy. Good motor.

Well someone was hotroding this thing because
they cut a hole in the firewall to fit the motor in
and made a new one. There was also a ford 9 inch
rearend just setting in the back all cleaned up looking
like new and ready to be put in the truck. The front
seat was also replaced with a black leather electric
bench seat that after I took all the tarps off of it still
looks new. I dont know what it came out of though
but it doesnt have any holes. I will go over to the
storage and try to put some of your good information
to work and see if I can find out what it is Thanks guys

Not to hijack the thread or anything, but if you plan to get that thing on the road again, I hope you equip it with the loudest set of semi air horns you can get your hands on. For some reason, I can just see that scaring the crap out of people.
