Re: EA block in Ef falcoon
You'll need to tap into the EA block as it has no provisions for a knock sensor. Also, putting an EF head onto an EA block will slightly lower compression as the EA pistons are dished and make up for it with a lump in the combustion chamber on the head, while the EF does not have this. Not sure if it would be noticable, just some food for thought. You'll prolly run into problems with putting an older engine in though, not sure what's the go legally were your from..
Other than that, everything bolts on perfectly, I've personally converted the whole front pulley setup and BBM manifold from an EF onto an EA block..
