I hope you understand, I´m not very good in english.
I have heard that, when they was making the scorpio Cosworth, that the engine had more power, but I don´t know how much and how they made it.

I have an extra 2,9 cosworth engine, that I maybe could try to make bigger.
It´s because of the law in Denmark, cars over here is very expensive.
Mustang in Denmark 680.000 kr = 130.500 $ (used car) If new it cost 158.350 $
When I make it with another engine I have to pay a lot of money in tax.
But it is legal to make it more power with the original block without turbo. and no tax
Or I can only get 20% more power total 248 HP, and if only 248 it is waist of time.
Then I prefer to make my 2,9L block up to 4,0, if it is possible, and 6 new pisons, 6 rods, crank and 4 camshaft and another settings in chip. What more can I do to get more power without turbu and blower (compressor). And how much power can I get? I got 207HP (only) now.
I have seen used DOHC heads twice on eBay, and one time almost the whole 2.9 engine was there. It is possible, but the cost will not be cheap, and operating it with a SOHC PCM would be best.
Is the 4,0 a 12V sohc?
Is the 2,9 a 24V dohc?
why then sohc pcm (what is pcm)
If possible, is it not easier to use the block from a 2,9 and bore it up to 4,0 than use a 4,0 and the other pistons, rods, crank and cam.(dimensions of pistins, rods, crank and cam) It has to be the same dimension as on the originally 4,0L?
All other on the engine should fit on?
