351C year

Hello, I´ve got 3 questions:
1-Why does every Cleveland part online is available between 1970 and 1974?

2-Was there a cleveland before 1970?

3-If there is a Cleveland before 1970, why would these parts not fit it?

Thanks,

Abel.

1st cleveland was available in '70. first 400 in '71. If there was a '69 cleveland the '70 part would fit it.

The cleveland was introduced as a replacement for the 351W but that didn't work out so well.

Australia used the cleveland design for over a decade longer than us yanks...developed a better block, awesome 2v closed chamber heads and the 302 cleveland.

The Aussie block is no different than ours and despite all the internet romour, no one can prove the blocks have higher nickle content. The very rare Aussie "XE"/"NASCAR" blocks are very hard to find and some of those suffered from bad core shift as those were cast from the same factory castings as the regular blocks. In fact, some of the these core shifted blocks were used in regular production cars which helped fuel a bunch of urban myths. I have several Aussie blocks and have bored those blocks and there is no visual difference to the US blocks except for the casting codes.

Yep, I know those guys and they have claimed that since they started selling on e-Bay a few years back. But, they can't back up that claim. I have a couple of Aussie blocks that I would cut up to prove there is no real difference......of course the blocks are worn out as I wouldn't cut a decent Clevo block.

what exactly would cutting up the block prove? I'm sure they would look,feel, smell and taste the same regarless of the nickle count right?

You would have to have a metallurgist account for the makeup. It sucks if ausford parts are bogusing the market...will have to call them and see what they say. folks can basically say whatever they want i guess.

I'm glad you brought that up as i took them for their word on that .... but wasn't runnin to get my wallet either...gotta save that for the tv evangelist thats healing my neck this weekend ;-)

From my limited understanding of metallurgy, you would need a sample of the cast iron to melt so you could determine nickle, moly, iron, silica count. So, I'd give up a crap block to determine that. Why I claim there is no difference is because I have had some bored and the blocks didn't bore any differently. It didn't take any longer to bore the Aussie blocks which, blocks with high nickle content tend to bore more slowly. And, these didn't affect the boring and hone equipment any differently than a standard Clevo block. I've worked with a machinist that has 40+ years of experience in boring Ford blocks, especially Clevos and FEs, and aftermarket race blocks and he felt the same way, the cast iron was no different that the US iron. Could these have a higher more nickle, YES. However, is it significantly higher? I doubt it. I'd like to see some Ford documentation that puts this to rest but I doubt you will ever find any Ford proof.

a guy had samples from 2 blocks tested, 1 block with the x's and y's in the valley, the supposedly "high nickel block" and a regular no x and y block. the x and y block had LESS nickel than the no x and y block.

Yep, old wives tale put to rest. Those were both US blocks so it would still be ggod to see what an Aussie block is cast from. I'd would imagine the mix is a little different because of many factors.....local laws, availibility of raw materials, method of casting, etc.,....

yeah, but to restate what was mentioned before, if any block did actually have significantly higher nickel content, anybody that had bored one would know it immediately and this info would surely come out by now? a "high nickel" block would also closely resemble stainless steel.

don't forget that the Aussies did change the size of the dizzy shaft support hole when they went electronic ignition. if i'm correct the electronic block hole is smaller and can be machined to the correct size for all US dizzies?

Yep, the hole can be bore to the early size. You will see these blocks refered to as "black blocks" and were found in the XD-XE Falcons that were built from 1979-1983.
