Pinto engine numbers

A friend of mine has got hold of a Pinto engine (I'm assuming in return for some random work as he's a bit of a wheeler-dealer. He wants to try and identify what size engine it is year and possibly a rough value, I don't know if it's possible from the numbers stamped on the engine, but I said I'd try for him.

The numbers there are:

EY19684

21030

164 (might be 16 4 - text message is a bit ambiguous!)

84HM6015B

Thanks in advance

The 16-4 indicates it's a 1600cc. A 2 litre would be 20-x such as the well known 205 block.

Value is precisely nil, or whatever the local scrappy will give him for 100kg of cast iron.

That's brilliant, thanks for your help

And manufactured in Oct 1984.

As mentioned, worth scrap value only

We can probably be a bit more specific which might help other people in the future.

EY19684 is the engine number and the two letters indicate the manufacturing date of the block. EY translates to October 1984 as has already been stated.

84HM6015B is the block part number and the 84 indicates it was a component designed in 1984, although not necessarily made in 1984 obviously but certainly then or later until the next redesign.

When the Pinto engine was first introduced in the 70s it was made in 1.3, 1.6 and 2.0 capacities, all with different bore sizes and the two smaller models shared the same 66.0mm crankshaft. The 2.0 had a 76.95mm crank stroke. In 1984 the range was changed to 1.6, 1.8 and 2.0 models all having the same 76.95mm stroke crank and different bore sizes to alter the capacity. This necessitated a new block for the 1.6 as the bore size dropped from 87.7mm to 81.3mm to accomodate the longer stroke crank at the same 1600cc capacity.

This new engine, the 1.6 Emax was fitted to Sierras from 1984 to 1989 and given the block part number with a 1984 design date we can be fairly certain this is what your engine is as the bigger bore shorter stroke 1.6 would have an earlier design date for its block.

So it will have a crank which could be of use to tuners of 2.0 engines but those are ten a penny anyway and the rest of the engine is useless as no one in their right mind would fit a 1.6 rather than a 2.0 to anything given they are the same weight and the 1.6 is much less powerful.

BTW the Wikepedia entry on the Pinto engine is largely nonsense as the author has confused himself with the 77.62mm stroke crank from the Ford Kent pushrod engine. Maybe one day I'll rewrite it.
