Do ford use the same engine blocks for different size engines?

I know some car manufacturers use the same engine blocks for a 1L all the way up to 2L but obviously with different size bore holes for the pistons.

Does anybody know if ford use the same engine blocks on there new fiesta, MK7 59 plates, from 1l up to a certain size.

I look at my block which is a 1.4 and it looks rather big for a 1.4 engine.

reason i ask is i'm thinking of putting some more power behind my car, and just want to know how much block i have, and how strong it is.

Not the same casting, but some are 'built' on a previous design. The small block Ford V-8 started as a 260 cubic inch engine, was then changed to a 289, then a 302 & finally a 351. All are basically the same design, with small changes. And, everybody has gone to a 'thin wall casting' process, to save weight & get better mileage. Back in the day, there was enough wall thickness to bore out a block for more cubic inches, but that is now 'old' technology.

The 1400 Zetec is not by any means a big block. A similar casting is used for the 1250 and 1600 engine, but deck heights are different, and the amount of space in the crankcase may differ relative to the stroke of the engine. Boring something out is not the only way to provide more power. These days, conversely, you will gain power by leaving the block alone. Try a pair of cams, Larger injectors, a remapped ECU, larger throttle body, free flow exhaust system, and a different oiled panel type air filter. Take a look at some of the sites like Demon Tweeks or Burton Power for hints as to where to make the best gains as a combination of mods, doing little bits at a time, but carefully matched mods, so they complement each other. It's no good allowing it to get loads of air in and out, if the engine can't process it all at once.

Yes. One example is that the ford 460 and 429 are the same block, just a different crank (mainly).

The 1.4-litre petrol engine in the Fiesta (also used in Focus and Fusion) is a variant of the Sigma engine family (see http://en.wikipedia.org/...gma_engine" class='ext_link'>http://en.wikipedia.org/...gma_engine ) and so is very similar to the 1.25 also used in Fiesta, the 1.6 in the Fiesta, Focus, Fusion (Euro-market Fiesta-based Fusion, not the US-market Mondeo-sized Fusion), C-Max, Grand C-Max and Fusion, and the 1.7-litre in the Puma.

The 1.4-litre diesel in the Fiesta is a variant of the PSA-Ford "Tiger" engine, and is related to the 1.5 and 1.6 diesels in many Ford, Mazda, Peugeot and Citroën models, and in the second-generation of BMW's MINI. (see http://en.wikipedia.org/...ne#DLD-414 )

Ford Sigma engine is made with displacement from 1.25L to 1.7L
