I have a Ford F150 with a 302 engine and need to know what that translates into liters.Thank you in advance. ---

302×2.54^3 = 4948.89cc I think they call the 300 (4916cc) the 4.9L I6 and the 302 the 5.0L V8. But 302CI would really a 4.9L as well, but they call it 5.0L, unless it’s actually 302.1CI then it does actually round to 5.0L. ---

If you have the old Windsor pushrod 302, then it comes out to 4.942 liters. Ford rounded up to advertise it as a 5 liter engine. If you have a newer F-150 with the coyote V8, then it’s 4.951 liters, which does round up to 5 liters. If you have a 2018 or newer F-150 with the 3rd gen coyote then you have a 5.035 liter engine as the Coyote’s bore increase slightly for 2018, increasing it’s displacement to 307 cubic engines, still rounds to 5 liters though. ---

Ford rounded up to advertise it as a 5 liter engine I have no idea whitch one I have now I was trying to check with Jasper engines to get an idea on prices as the one I have now is burning too much oil all I know for sure it has very high milage. ---

Enter “convert 302 cubic inches to liters” in Google. ---

Easy math… cubic inches (302ci) divided by 60.9 = Liters Liters times 60.9 gives you CI… As already said, Manufactures round up/down to make look better… It’s not rocket science, don’t overthink it… 302 / 60.9 = 5.0L 5.0L x 60.9 = 302 CI ---

That has the Windsor 302. ---

I’ve seen older hot rodders use a few different numbers… Either one will get you close enough… Remember that a Chevy 305 & 307 are both 5.0L, but the Chevy 302 was a 4.9L… The Ford 300 I6 is a 4.9L… So you have to have some common knowledge also… ---

Yes, games played with stated vs. actual displacement. But the conversion factor is what I mentioned above. ---

I’ve never heard “Windsor” attached to the 302. I’ve heard it for the 351, i.e Windsor 351, b/c there’s also a Cleveland 351 , different design, same displacement, but different stroke & bore. Are all 302’s Windsors, or are there Cleveland 302’s as well? ---

Read all about it: [Ford small block engine - Wikipedia](https://en.wikipedia.org/wiki/Ford_small_block_engine) Windsor displacements: - 221 cu in (3.6 L) - 255 cu in (4.2 L) - 260 cu in (4.3 L) - 289 cu in (4.7 L) - 302 cu in (4.9 L) - 351 cu in (5.8 L) Cleveland displacements: 302 in3 (4.9 L) 351 in3 (5.8 L) 400 in3 (6.6 L) ---

My quick research suggests 302’s were made at the Cleveland plant at first, and nowhere else (at least in the USA area). So they were just called 302’s. Eventually the 302 production was moved to Windsor, and that’s the only plant that made it. Presumably the 302’s made at the earlier Cleveland plant are more or less identical to the 302’s made at a the later Windsor plant. Just to keep things interesting, there’s also a “302 Boss”, which I believe has the standard 302 block but is equipped with Cleveland heads (presumably from the 351 Cleveland). And there’s a “302 Cleveland”, but that was made at a Ford Australia plant, only sold in Australia. Not sure why it had the Cleveland moniker. ---

You’re incorrect. The Cleveland and Windsor blocks were different. ---

From the 1978 model year, the 302 became more commonly known as the 5.0 Liter, although its metric displacement is 4,942 cc (4.9 L; 301.6 cu in). Ford may have used the “5.0” moniker to distinguish the 302 from their [300 cu in (4.9 L) inline six, which was known as the 4.9. Also from [Ford small block engine - Wikipedia](https://en.wikipedia.org/wiki/Ford_small_block_engine#:~:text=From%20the%201978%20model%20year,was%20known%20as%20the%204.9). ---

What’s different about the 302 blocks, comparing the first ones made a Cleveland vs the later made at Windsor? [Next page](https://community.cartalk.com/t/for-the-math-experts-on-this-f0rum/193875.md?page=2)
