Is there diffrence between a pinto 205 block and a cosworth 205 if so what and how do you spot it?

 

The 'Cosworth 205' was merely selected for there tighter bore tolerances, if you look by the dizzy you will see four number, representing the tolerance for the cylinders, Cosworth asked for only grade 2 and possibly 3 from memory to be delivered to them.

So you should see 2222 for example.

Once rebored this figure is irrelevant.

In addition they will have YB then a number above the water pump on the front on the block.

That aside it's the same block.

So a pinto block can take same power as a yb block?

 

Yes, they are exactly the same, just handpicked for the sole reason above.
