Do some Googling, You need a Ford crank but it needs to be cut and shut and other mods. I don't think you do it to a 202 though, you need the smaller mains tunnel from memory so you need a 186 block or maybe a 179. Lots of $ though when you could do it far easier and cheaper with a replacement 6cyl like a VN onwards V6 conversion or a Chev 250 or 292ci 6cyl. Even a late Ford engine. What is it going into?

Agreed. The $$$ spent is not worth it. They don't rev that well either.

221 Ford cranks are like hens teeth these days & a lot of machining is required, not to mention the short pistons etc. which may be custom.

If you want to keep the Holden 6-cyl, get a good head & put EFI on it.

If you want some other ideas, have a read here:-
