well it depends

i think cause your increasing the capacity, you'll still need to go thorugh some s**t to get it lic

But LPG is the way to go, for emisons, other wise a EFI set up would be needed to comply

Best to speak to a workshop/engineer that can do mod plates, they will be able to tell you the legalities to doing it.

Here is a link to more links regarding this.

There is a fella on FFAU who lives up Cairns/Innisvale?? way who legally converted his EA to run a clevo on straight LPG. Backed up with a T5 as well.

i think from memory you have to remove all remnants of the original fuel system (tank, lines etc etc)

i think it is doable though

Im pretty sure that you can fit an older engine into a newer car but the engine has to comply to the emission standards of the date of manufacture of the car.

The other worry would be the capacity increase is quite large. In nsw i think only 10% is aloud, so based on the largest engine available for the ef, you fall short. the maximum would be 5.5L (but hay your in qld so it may be dif) + there is a bit more weight to support even compared to the Windsor (afaik) so it may need a bit of chassis work.

Definitely speak to an engineer before going any further than just thinking about it.

Oh and ford made a EA 351-GT (clevo powered). But it never made it into production.

I believe that the 351 GT EA prototype was in actual fact Windsor powered with a motor from a F150. From memory the clevo was too wide for the bay for it to be a production possibility.

It was windsor powered, the 351 W having a higher deck height made it a very very very tight fit in the engine bay, and probably not legal at the end of the day.....

Easier to just rebuild & turbocharge your XR6 engine, even with the turbo gear it shouldn't weigh as much or more than the 351 clevo, and should go harder to boot!

Cheers

Oh, i thought it was a clevo and thats why the deck height was too big for production.

My bad i stand corrected.

Yeah but the biggest problem you can not fix is it will still sound s**t, like trying to make a silk purse out of a sow's ear.

The 351W has a different block to the 302W, deck height stands taller, heads are further apart & manifold from 302W won't fit.

The clevo block on the other hand, the bottom end can be changed from 302 to 351, and even stroked to 383.

I dunno about that, i've heard a couple of mild turbo 4l's and they didn't sound too horrible, but i've also heard some really hot turbo 4l's & they did sound good, but i don't think it was better than the sound of a thumping 8! I grew up around hot 302 & 351 clevo powered falcon's my parents owned, and hot v8 holdens my older brothers owned, a HG 308 prem & a genuine HQ SS 253 4spd. I've got a 253, stock internal in my HZ pano, with stock manifolds, just a nice 2.5" system with a hot dog & 1 sports muffler, and for a stocker man it sounds great. I can't wait to get extractors on it!

My EB is just a 4lt 6, but i've got extractors, 2.5" system from cat all the way back, 1 sports muffler & 1 res. It sounds good for a legal ford six. It sounded better without the res but it was way too loud to be legal. Damn fun police!

Cheers

Yeah i knew the 302w and the 351w are different blocks.
And the 302 clevo and 351 clevo where the same, they have the same bore size but different strokes.

I just thought the ea gt had a clevo, i was mistaken.
