Frankenmotors

[dwilliams]

There have been several proposals to put a pair of Lotus DOHC four cylinder heads on the Rover V8. The bore spacing is almost the same. A couple of people bought heads and announced they were beginning the conversion, but as far as I know they never finished.

Too easy conversion is to put Zetec block under CVH head (2-litre CVH).Makes fun Escort.. Friend had one turbo example;made 330 hp little over 1 bar boost.Of course I had ported the head

Anyone here finish any of these things?

The crank and rods from a Duratec 2.3 fit in a 2.5 block so you can make a 2.4 with 500 more RPM over a 2.5. The whole lot is very similar in dimensions to the other engines so you can replace the 1.8 or 2ltr in a Miata with any of them easy enough.

My old friend Wes burned a piston in his dirt car a couple weeks before the end of the season.

He got out his boring bar, found a Ford piston in the scrap heap, bored the block on the floor in his disheveled shop, drilled out the piston and found a bushing to fit the Chevy pin screwed it back together and won the feature the next week.

He said that Chevy motor ain't smart enough to know it has a Ford piston in it.

That's easy enough; I used a lot of Chrysler rods and Chevy pistons to make 351W strokers. Tip: it's a lot less work if you start with Chrysler 3.9 V6 rods instead of small block V8 rods... I also used Slant Six rods and 400 Chevy pistons in some FE strokers, 2.3 Pinto rods and Chevy pistons in 302 strokers with cut-down 351C cranks, etc.

A lot of the things we used to spend long hours on the crank grinder and milling machine to make, you can buy cheap enough online now. And I, for one, don't miss the "good old days"...

That's not much of a conversion, since not only did the Zetec and CVH share the same block, Ford did make 2 liter CVH engines.

Awful things. They are very rare since they had a habit of dropping the #4 exhaust seat after it got hot. Or maybe just at random. Rare to see them with over 200k miles, they usually dropped a seat long before.

Local junkyards were selling Zetec swap kits (engine/accessories/computer) for half the price of a 2.0 SPI, if they could even find one.
