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

My bad i stand corrected.


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.

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.


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.

Ride: BA Ford Fairlane V8

Location: Lower Hunter Valley
NSW, Australia

The fact that Ford made the excuse that the '51 was too big was a weak limp wristed excuse. There is more clearance for a windsor 351 in a EA-EL engine bay than a 5.4 DOHC V8 in a BA. Sorry for going off track but Ford were just starting to pull their heads out when that EA prototype was built. Still took them a while(read Tickford) to release a decent windsor from a salesroom....

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.

Not true, it goes on weight as well. When i looked at doing my EF, i was told 484cui was the biggest i could go for the weight of the fairmont. I dont know what that is in litres, but a 427 is 7 litres

yea i think weight is also a issue but if ashcook can get a 351 into xf which had a 250 as ateh largest option. i can't see 2 much drama.

now how easy of a job is it? and what do u reckon it would cost?

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.

What is his user name?
