I'd say there would be a very good chance. In fact if they stop making the 5.4L blocks then Ford Aus would have no other choice but to use these blocks.

 

It's meant as Ford's answer to the Hemi, so does that mean an "out of the box" power rating of about 260 kw? Will that equate to a GT spec 330 - 350 kw? Sounds about right to me.

 

It could also mean we get stuck with the 5.4's baby brother the 4.6L

 

Maybe, but car sales is partly a numbers game so it would be difficult to compete with a smaller engine than the opposition.

Absolutely no chance in hell! Do you think they would have gone to all the trouble to get the 5.4L into the falcon when the 4.6L would have been alot cheaper and easier? Ford stated the 4.6L didnt have the low down torque characterisitics they were after when choosing the engine for the BA. I remember reading about it in an aticle a few years ago.

 

We are talking about ford auz here. I know it probally wont happen. But just think how heavy a block like that would be. People are complaining about the excess weight of the boss now year alone a larger engine again. I have no problem with the current engine big power will be unleashed with raised rev limitits and bigger cams. But bigger is better as long as it's an alloy block.

 

I doubt it will be an alloy block, and I doubt the block will be any bigger. I think it will be a revised bore, where the bore will be larger. I don't think the physical size or mass of the block would be any different.

 

I dont understand the whole bore vs stroke stuff (i know bore is cyclinder width &s troke is the stroke length), but i thought you couldnt stroke the 5.4 cause theres no room to.

 

No, but Ford have enough room to bore the block out. The 5.0L Cammer block runs 94mm bores compared to 90.2mm bore for the BOSS motors and they use the same block. I think this new Triton block has to have >96mm bores (assuming it has the same 105.8mm stroke) to get any where near 6.2L capacity.

 

Ford Oz didn't want the 4.6 because they believed that Australians wouldn't like the idea of such a "small" V8, it was purely a marketing thing...

the 6.2 would be sexual though....hopily they'll stretch the rev-limit to 6400rpm due to the better bore and stroke ratio....

Dave.

Thats correct. The current stroke length of the BA V8 is at the peak length for peak piston speed. However I believe this is all calculated as a ratio of the bore (width) versus stroke (length).

If you "stroke" an engine you end up with a longer throw of the piston. However the other way to increase the capacity of the engine is to increase the cylinder width (bore). This has no bearing on the size of the block and heads as you are increasing the interior room of the cylinders.

As this will effect the stroke/bore ratio this will allow for a few more rev's to be piled on.

Increasing the bore may effect the size of the block because the bores need a certain amount of space between each other for water galleries and also for strength so that would result in a bigger block and the heads would need larger combustion chambers to match the bigger bore.

 

A bit of head porting wouldn't go a stray. The block will be a modular so you can still use the Mustang alloy heads I would be guessing. I don't know how thick the cylinder walls are in the triton block, to make 6.2 litres you'd need to bore it out quite a bit. I wonder if the 6.2L will be just a bored out 5.4L triton block or if they start from scratch.

 

The triton 6.2 is not a 5.4 block.

 

Is it really going to be a Modular block? I don't see how they can get a larger bore and still use the same heads.

 

anybody got a spare shoe horn to help me get one of these between the rails of the Ute

 

i wouldnt be surprised if when the 5.4 grows into the 6.2, the 4.6 has a growth spurt as well. it looks like it'll grow out to more than 5L as well
