what does the leters mean on an engine. im totally confused about it. i know the 302 is a 5.0 leter, but what does that mean? why do they now use leters instead of cubic inches?
thanks for helping me out guys

302 is the cubic inches of 5.0 it sounded like u explained it to yourself, if you are talking about like a 351M or a 351C heres some quick definiations
C= Cleveland
M= Modified
W= Windsor (small block)
all three of the engines have 351 cubic inches, which is some where around 6.??? i dont feel like doing the math. but i think thats what you were getting too.

i've had a number of people ask me what the leters mean. i know that the 351 are around 6, because my dodge 360 is a 6.1 leter. i was just wondering what that leter thing means. what does it have to do with engine size.
i think im just confusing myself and everyone more

lol, alright lets try again lol so you are asking why they make a 351W 351C and 351M, well there is a nice long essay about them somewhere on this site, but not sure where, the long and short is 351W is a small block. 351C and M are big blocks. the M replaced the C. getting any clearer?

The letters have nothing to do with the size of the engine. Whether or not M stands for Modified is debatable.
A 351 CID engine is 5.7 liters, the 400 is 6.6 liters. Liters and cubic inches are simply different designations for expressing the total amount of volume that the cylinders contain. Cubic inches is imperial measurement and liters is the metric equivalent. Motorcycle engines have been designated by the metric system for years, 500cc, 750cc, etc. A cc or cubic centimeter is another method of expressing displacement metrically. A 1000cc motorcycle engine is a 1 liter engine. A 5.0 liter car engine is a 5000cc engine.

You can't really break the Ford engines into the same catagory as Ch*vy engines. The 302 and 351W are commonly called small blocks but Ford had several different styles of engine in production all at the same time. The FE and 385 series are definitely large engines but the 352 FE is only 352 CID. The 351C, 351M and 400 are all in the 335 series. It is it's own engine series and isn't really a big block or a small block. The 351C has the same bellhousing bolt pattern and bore spacing as a 351W. The 351M and 400 have virtually the same deck height and bellhousing bolt pattern as the 429/460 engines but the same bore spacing as a 351C and 351W.
Easiest way to do it is call them Windsors, FEs, 385s and Clevelands or 335s.

There is currently a write-up on the C,M,W differences in Fordmuscle.com. They will allow you to read about one page and then you have to suscribe. Still, the one page sheds some light.
There are 61.025 cubic inches in a liter (for practical purposes just say 61 ci/liter), but don't try to back calculate from a liter designation such as the 5.0 as it is rounded off (and the wrong way!). The actual cubic inches of the 5.0 calculates to just under 4.95 liters and so rightfully all those 5.0 Mustangs should be 4.9s. However, let's leave it alone as then it would get mixed up with our wonderful 4.9L truck six (I think the straight six is about 4.919 L and the 302 is about 4.947 liter, but using 61 instead of 61.025 may edge it up above 4.5). Also, my understanding is that Ford had one 352 cubic inch engine that actually was 351, but to keep it separate from the other 351 called it 352--I think that was a FE engine.
Now, if the 351 is precisely 351 cubic inches, then it is 5.754 liters or rounded to 5.8 which is what I think Ford does.
BTW: A Dodge 360 V8 (assuming exactly 360 cid) calculates to 5.9 liters, not 6.1.

Nah, this is overkill:
300 CI/61.025 = 4.916018 (cubic inches to litres)
4.916018/4.55 = 1.08 GALLONS!
302/61.025=4.9487914 ~ /4.55=1.08764....
So we're driving one gallon trucks, then...

Great Idea Greywolf, but my conversions table gives me a different figure:
Liters * 3.7853 = gallons
or
cubic inches * 0.0043 = gallons
Now that is even better because my 300 incher becomes a 1.3 gallon or a 5.2 quart !!!!! Hey yeah! 5.2 is better than 4.9.
