Hey, I just wanted some feed back on this idea. Can the EFI 4.0 SOHC head be fitted to early model 250 X-flo heads. Obviously I would have to modify the original crank for a timing pulley, I'd possibly go belt driven instead of chain. Can it be done, are the head bolts simmilarly possitioned?

No, timing belts are similar to glimmer drive belts and run a sprocket type gear and a belt with teeth. All I need to know is if the head studs and chyamber spacing will be similar

That would have been Krogdahl (sp?) Engineering. I think that they cost about $5000 a go though. |

Yer I read about them in SM aswell, I'm only asking this question because I've got an engine of each, I'm rebuilding the 250 x-flo as the OHC 4.0i put a leg outta bed and I can't be bothered fixing the hole in the block. Being the same capacity i thought

At a guess I would say that Ford left the bore spacing & head stud placing the same. I am basing this on the theory that they could not even be bothered to move the distributor to a decent location when they went OHC so why would they waste money on chang |

The thought never even crossed my mind to compare head gaskets. Cheers. I thought the studs might be diferent because they have to clear the cam instead of rockers but I havent looked so I hope your right.I'm getting another 250 block next week off a mate

I can't put all the OHC engine in beacause it got a gut full of water one day when a road was slightly flooded, and last time I checked water don't compress!
Result; One shattered piston
One bent conrod
And one hell of a hole in the
