<p>The 3.54 will work with an xflo if you're not interested in acceleration/performance, it wont improve fuel economy since its the Duttons awful aerodynamics that affect FC most. Remember the 3.54 was only available in pinto engined escorts for a good reason. If its only pulling around 3500 rev.min in fourth at 70mph then you'll likely be in third a lot at speeds below 60mph Though it pains me to say it if you want cruising speeds with low engine speed then fit a Rover V8, at lease it'll sound…</p>

<p>Just looked it up again. It is about 220 km/hr @ 6000RPM in 5th gear, you're right. That is over the top.</p>
<p>Just did a comparison of 4 speed and 5 speed with 3.54 and 205/60/13. Shifting up is set to 6000RPM in the tables. Speed is given in km/hr.</p>
<p>What about reducing engine speed with the 5th gear compared to the 4th gear? Somewhat about 500 RPM on 100 km/hr. Is this remarkable on the crossflow?…</p>

I've got a 2.88lsd jaguar powrlok out of an XJ12 in mind. 0-60 in no idea but the V8 pulls 3rd from walking pace to 90mph. I've hit 116 in fifth at about 4 -4.5 and the engine revs to 7k. 1st and 2nd gear are hilarious and 1st just sits the rear near the floor before the wheels spin. I had a 3.54 in it before and it was too low for the power and torque of the engine. When driving on back roads you can just use 3rd and 4th gear and it bombs along nicely.

<p>Patrick, I think the 180km/h was in 4th gear. 5th would be more like 220km/hr. It would get to its top speed in 4th and 4th would be the best gear for motorway driving. 5th might be okay at 100km/h on a level road but it would be struggling below about 70km/h and, with the top speed in 5th being less than 150km/h (4000rpm), then it will never feel like it has got into its power band.</p>

<p>I was only thinking about the engine sound. It would feel like you wanted to change up all the time that you were cruising and, with plenty of response available, it might feel a bit 'on the edge'. My Melos had a 4 speed with a 3.89 and it seemed very low geared at 50mph (with a 2litre Pinto). It'd be fine on a track but tiresome on the motorway.</p>
