Not really.... The 5.0L moniker existed to differentiate the 4.9L 300 I6 from the 302. The subsequent stigma that eventually became associated with the badge didn't happen until the 87-93 cars IMHO. That is when the "five point oh" thing came about. Early "5.0L" badged engines, like those in the F-150, Panther cars, Thunderbird....etc were not known as "5.0L" cars. There was no identity associated with the badge until the last-gen Fox cars.
the HEMI moniker's infamy on the other hand was directly related to the fact that the engine had hemispherical heads, and the name, and the engine, instantly became synonymous with performance.
The reincarnation of the name was a logical move because of that yesteryear stigma, even though the modern incarnation does not wear hemispherical chambered heads.
Now, some fun regarding the displacement of the 302:
302ci equates to 4948.893 cm³. If we round up to 4950cc (4.950L) and then again to take this to our regular two-number litre designation, the rounding rule dictates that 5 is rounded UP. Which brings us to 5.0L.
HOWEVER
the 302 is not necessarily a 302.
4.0" bore
3.0" stroke
301.59ci
Converted to cc, we end up with 4942. Which would be rounded DOWN to 4940cc, or 4.940L. Giving us a 4.9L engine.
But if we use the metric numbers:
102mm bore
76.2mm stroke
303.97ci
So if you use Ford's "less than accurate" 302ci designation, it does round-up to 5.0L. If you use the metric engine dimensions.... it is 5.0L. But if you use the imperial bore and stroke numbers of the engine, it is 4.9L by the math.
Sufficiently ridiculous for sure
Absolutely correct and the original poster has no clue. Good job.
