To prove your blindness
It was me who made that comment not pro240c as for me being down under the reason why I think windsors are lighter?

The windsor was the first design to break away from the first Y type v8. Ford was the first company to mass produce the v8.
Even the first of them weighed less than a chevy small block.

60s Windsor 289/302 - 460lbs
1960-70s Chev small block - 575lbs
this is cast iron everything no alloy inlets.

Even the Boss 302 won the 1970 Yank SCCA in a oversized heavily made mustang designed by wait for it! an ex-Gm design engineer. And not that Im a 1970 mustang fan (they arent my taste), they are the heaviest of Mustangs made.
As for Gm you gotta hand it to them for making so many people blind with their marketting.

In Australia Jap v8s are not allowed to compete with the ford vs holden field.

If the Jap v8s were allowed to compete here then sales would go down completely.
Im sure the same applies in the U.S.

Sorry Dodge but Im not such a hemi, ford or chev fan however I do like cars from all these companies.
As for the corolla K series, It was an original Toyota design still used in Japanese cars such as the LiteAce or Town Ace the last here on our shores had the 90mm stroke version of the 5k called the 7k with a capacity of 1900cc. The A series design dates back further with the Pom original maker and improved in Jp hands.
The K series is still used in Forklifts and so is the R series. The problem is Toyota has made more engines than any other company and keeps coming up with new ones often unlike Chev.
This is where Chev has intelligence where they have more aftermarket parts available than any other maker. The next company on that list scarily is the old VW flat four.
