OK, I'll admit it, I'm a mechanical noob! So, here's my question: What makes a 302 a 4.9L or a 5.0L what does that mean?
The 302 cubic inch V8 became the 5.0 liter V8 when the measurement went metric. The 300 cubic inch in-line six cyl became the 4.9 liter when the measurement went metric.
Technically Yes. But it is common practice to refer to the older engines as a 302 and the newer roller cam versions as a 5.0. If somebody tells me they swapped in a 5.0 into an old car I assume its an engine from a mids 80s to Early 90s Mustang or something similar. If they say it has a 302 in it then I think its a standard flat tappet cam older version 302.
Doesn't matter because it would still be a 302 or 5.0 block. I never hear of anybody adding the OVER BORE it took to clean up the cylinder to the cubic inch...untill I joined this forum.
A stock bore and stroke 302/5.0 is actually 301.9 cubic inches. Ultimately... It comes down to bore size (Dia) stroke (Crank throw) and swept volume, to determine displacement...just sayin"
You don't get out much, do you? LOL J/k I see/hear it all the time, especially when it's done on purpose to increase size.
Whenever I hear "Its got a 306 in it" at a car show from some punk kid I want to slap him. Its a 302 engine, yes its been rebuilt and bored to repair it but 302 is what you call it. Ford didnt make a 306, you dont buy parts for a 306. its a flippin 302. Now if it is STROKED then you can have something to brag about and say its a 331, 347 etc. but 4 more cubes to make it a 306 or a 305.498847 whatever is nothing to brag about thinking you got something.
