what the exact differences are between a 1970 u.s 2v block and an australian-made block! (i think the aussie ones were late 70's-early 80's) (i know there are rumours/theories, etc, on the differences but i'm looking for facts). also, is it possible to fit a distributor from an australian cleveland into the afore mentioned u.s cleveland!-and if so, what modifications/s are required! (i know they don't drop straight in) (and before someone asks "why do you want to!", i have good reason to). cheers in advance guys.

Is there a difference!I bought a Mallory Dizzy for my 302c, which also fitted the 351c, and even the 460L (about the only part that works between the SB & BB I think :-).

cheers but i strongly suspect that your '302' had u.s block in that case-in fact u.s distributor manufacturers (msd for example) have a footnote stating that their cleveland distribtors (which also fit 460's etc) "will not fit aust clevelands".cheers

yep ive done that but its not actually as simple as '2v' and '4v' as there are both u.s and aussie 2v's, etc.i figure someone out there will know the exact differences and what would need to be done to get an aussie distributor into a u.s engine. cheers.

Interested to know more - hopefully someone knows.The 302C I had was in an XA Fairmont (original motor), the 351C was actually a stroked 302C (crank & rods), the 460 directly from US.
Well i bought an Accelelectronic distributormade in USA for my XD 302cdidnt say anything about any difference between the 2 & it fitted & worked perfectly . The diference in the blocks was in the casting thickness , all the hot rod boys will tell you the aussie blocks were better formaking hi HP .

hmmm.interesting.ive heard several times that they are different and at least in this area. i just checked the msd site again and in the info for p/n 8350 it states that it isnt suitable for xd and later australian cleveland engines. im not sure if xd onwards are different to other (earlier) aussie blocks-or if there even were any cleveland blocks made in australia previous to xd (i must check out that link etc). any further info most appreciated cheers.

xe was the last australian car fitted with a cleveland november 1982 im reliably informed.im wondering when cleveland started to be cast in australia. the real early cleveland powered australian cars (eg xw gt's) had american produced cleveland fitted i believe.

Why don't you have a good read of the link I put up!

Interestingly enough the Ford Cleveland 302cid V8 was an Australia only engine and none were built in the USA or Canada. All the 302cid Ford V8's in the North American market were indeed only the Windsor version.

its a great link thanks, ive had a quick look and its a lot to take in so i'll look at it properly later tonight. in the meantime i thought i'd solicit info from people while its a good time to do so (being a sunday evening). cheers mate

Actually the 302C was a de stroked 351C, the 302C was not produced in North America at all , it's peculiar to Australia only.

Actually the 302C was a de stroked from 3.5" of the 351C , to 3.0" stroke for the 302C. The 302C was not produced in North America at all , it's peculiar to Australia only. Hence the nick name"Down Under Block."

p.s from what i saw quickly my distributor question wont be answered in that link (although there's tons of other really interesting stuff in it) and im beginning to wonder if there's a difference betwwen the earlier aussie-cast blocks and the later aussie-cast blocks (i.e xd-xe) in that area.

interesting read Jimma. i have 2 clevelands, and i just did a check on the one on my engine stand. From the engine number, it is a 1981 motor, from brisbane, and was fitted to a Fairlane Marquis. According to that article, it should be a 'pillow' block but it isn't. And there are two different dizzy set-ups, just not sure when the change over was but i guessing it was in the same era, XD and XE models, when they switched to electonic ignition.
i have measured the shaft of my dizzy below the drive gear and it measures 13.1 mm. if anyone has an earlier motor could you measure yours and post, i am curious now.

The Cleveland 302 was an australian only engine made 1972 to1982 it was made to compliment the 351 as a smaller capacity from the geelong plant. It was a viable alternative to importing the 302 Windsor from the US as they already had the tooling for the cleveland block.
It was called the 302 Cleveland as apposed to the 302 geelong, the theory being the ford engineers called it what it was, it looked like a C so it got called a C not a G.
they did this by reducing the stroke of the geelong 351 block and increasing the Conrod length. the aussie made Clevelands also had a smaller combustion chamber to meet emission standards that were on the table for discussion at the time(a little way off yet).
the last aussie produced 351 block was 1982 and your vehicle ID number would look something like this.JG32AR33633K
The stock of engines lasted till 1985 and used in the bronco and ambulance.
In theory you could take the 302C from aussie and put the short rods and 351 crank back in, change the carbie and have a genuine 351 cleveland.

After this generation of 351's the next were based on the 400 truck block.
this is where the significant issues arise with interchangeability of parts as the 400 truck block is different to the 351

just had a look at that link Jmma, picked up on one incorrect post. JG ID is from Broadmeadows, Sydney. But it did mention the two different shaft sizes, 12.5 and 13.1 mm.
