XD408

Hey guys

Ive finally started on my new combo the rear suspension is being upgraded with the ladder bar suspension, the diffs also being upgraded with a nodular housing, and alluminum pinion support, but the biggest change is going to be the with the engine. I purchased a Dart block with 9.2 deck height which should arrive soon, with the larger bore size than a standard windsor of which weve ordered and piston change to match it increases cubic capacity to 434 :). This along with the larger custom camshaft as mentioned before provided by CHI and now to be 13.1 compression to run methanol were aiming for close between 650-700hp (previous engine on pump fuel 11.1 comp smaller cubes and tiny camshaft produced 580fwhp) Ill be posting pictures of the build as we go, and a short vid of its start up hopefully by the end of next month, Im eagerly awaiting its completion and had to tell my fellow Ford enthusiasts, should be a 9 sec street car turning loose on the streets of Perth soon

That 700hp figure is just a guess any other guestimates of power figure??

Don't know about Perth, but ladder bars are not legal in NSW. Have you considered a superior 4 link?

Iron or alloy block?

434 from a 9.2 block. What stroke and rod combo?

Sounds like you will lead the field XD408. Hope it all goes well. From my knowledge of XD platforms, you are definately going to need some serious chassis strengthening as well.

As to HP you sound conservative IMO, but better to do that I suppose than have some of the more pedantic FF members at your heals quoting your HP claims at some future point in time.

It street registered at the moment not street legal, im not sure wehter either option is legal on w.a. roads we got a ****ed up system over here, but ive driven it on the road on semi slicks with the cage and pretty serious engine for 2 years and never got stung. When i do it'll just be driven on two day work permits :). I only went ladder bar mainly because we wanted to retain the leaf springs and not have to **** around with moving shit which we have to now anyway but ive got them already so were just gonna use them. Its a cast not alloy dart block, ive already got the 4.00 nodular eagle crank (internally balanced) and eagle H-beam 6.2 rods.

What about a caltrac type set up?

Then you'll need something like 4.156" pistons to achieve 434. Must be one hell of a tuff block.

I think the 9.20 block is the same height as a 302W, while your 408 was built around the 9.70 351W block?

Which intake are you planning on using, because you wont be able to use the old one?

434 is one big small block BOSS.

700HP that's going to need a 1/4 chassis and 4 link rear end as well as bracing to the front rails and a chute most likely for the strip. If it hooks up it will twist the car like a piece of celery with that much HP.

windsor, all aftermarket blocks are windsor based, except those new aussie alloy blocks.
