Jason I have seen a dizzy driven off v belt on a v6 commodore engine that was converted to run on carbs.  it is real old school speedway engineering but it can be done.
 
would I bother doing it to a BA motor - no way.  with cam lift limited to .515" because of the rocker gear you can not possibly take advantage of the extra flow of the cylinder head with only that amount of lift.  duration would have to be increased to the point that I doubt a dual cam engine would really work.
 
I could make a crossy pull jesus off the cross and run 12s all day for the price of making the ignition system work on one of these and then get it all complied. 

So a bit of internet research on the American 5.0 mustang forums shows that with a 331 stroker, afr 185 heads, hyd roller cam around the 580 lift and 240@50 will get you into the 350rwhp territory in the factory block.
 
Another idea is this:

The yanks have tested it and based on a 302, 170cc alloy heads (no further description), 264 cam (again no full description) and 750 carb plus 6.6psi made 490hp.
 
Landed in NZ from Summit is $3600nz, plus taxes being 15%.

Thanks gerg, it will be my project tonight.
 
The new flywheel turned up yesterday, so all going well I will sort that out as well, it is suitable for 10.5 and 11 inch clutches, so I'll throw my 10.5 on for now.

I've only driven a couple of 5.4 boss equipped cars one an xr8 the other a GT. Both left me underwhelmed. No offense to anyone with one of these but they didn't do it for me at all. The Miami motored cars would be the shit I reckon and if you were going to the hassle of such a swap it'd be the only way to go.

Yet truck bottom end with the mustang heads fitted here.

Do you have the fg gt with the Miami?
 
I have researched a bit more and measured the bay, the coyote will drop in very snuggly with the factory shorty headers. Looked like custom headers if long 4 into 1 are desired.

Quick check on summit racing and for $11000 NZ I could have the 420hp na coyote and harness control pack/loom dropped at my door, including tax and freight.

There is a PDF at the bottom of the link with engine dimensions.
No matter what v8 I think once you put good flowing pipes on it it will be tight thanks to the towers. I'm sure we all have very fond memories of trying to get the back drivers side exhaust bolts in on a Cleveland with extractors! Lol!

That's a great test there Sly.

Yeah I have looked and they are pricey for what they are.
 
I have mate who has a few spare, hopefully he has a manual one to suit cleveland.

Yeah same weight as the stock cast Cleveland.
 
Its quite surprising how heavy some of the expensive brand billet ones are.

What's wrong with the good old 'poor man's' 9"  ???  Seen plenty of them in speedway Cortinas and they come up on speedway forums all the time.  Good choice of ratio's and strong as an ox with 30 spline axles in the diesel models.  Gav runs one in his KE35 corolla with 450@ the tyres so if that's not strong enough I don't know what is.
 
We run one in Brenton's Cortina speedway car with 5.8 gears.  I'd go that way before I went to a power robbing - heavy as fek 9"

The Hiace diff I putting in mine has 4.3:1 ratio but im looking at 3.7's. Lsd center in that ratio is $1000 alone. 30 spline axles and disc brakes. Garenteed win

What year is your EL XR8?
 
As some or the last of them came fitted with the AU intake, however you will still have the crap E7 heads, which are a huge restriction on their own.

Yeah it is shit house.
 
Turns out to be too short, got the proper one/length on the way.

Its a bit like a clevo and a big block, lots couldn't tell the difference when sitting in the engine bay.

Small price to pay for our relaxed but safe modification laws haha

I have the crs bracket, 99% the same as the one above and then got this adapter which bolts on.

Yes I have and the purchased a piece from summit, I'll get the part number, worked a treat.

Ok here we go.
 
This photo is of standard springs and blocks not settled or loaded etc
 

 
Next shots are new springs.
 

 

 
For some reason they are small photos???

I have then in, and got to say I'm happy as a dog with two dicks.
 
I ended up with two the same, or both have the part number for-500/140. I then made an enquiry with King springs in Oz, they said it's all ok.
