okso could i just get an old 351 block and bottom end and fit my parts to it??

YES except for sump as it has different mains.. You wouldn't run a std sump once you see these anyway!!

The 5.0 lower inlet manifold won't fit.. Due to higher deck..Heads are further apart..
Check thread above where XR9UTE has done 351 conversion..

Some clearance with extractors ?? But I doubt that would be a serious issue..

Have a look at this...
http://www.perthfalcons.com.au/index.php?showtopic=1866
It's the engine from my ute in the article above. So we're talking very mild yet my '08 Super Pursuit couldn't keep up with it. Send a pm to shannon(eb2flyz) and ask him what he thinks...1st and 2nd gear are a waste of time in this car.

Sorry above link wouldnt work??

is it worth the trouble converting to the older bigger block engine or should i just get a 302 windsor mexican block or even an older 70's block??
Im going twin turbo and dont want to be hovering the 500hp limit knowing it could go bang any second.

The link works when I click on it.
As I said already the 5.0 front dress goes straight on.
I'd get a Dart, World, or Ford racing block if using turbos.

off but on topic, what is the physical difference in the blocks between 1 piece and 2 piece rear main seal?
as in what stops you fitting a 1 piece rms to an older block or an aftermarket block that says it suits 2 piece?

also you've got to be a member on perthfalcons to view that thread, probably why it didn't work eboost.

IMO you have two realistic options if you are pushing 500HP or more and you want it to last

1- Buy an aftermarket 8.2" block, an aftermarket crank, rods and forged pistons

2- Buy a 351W, forged pistons, a new lower intake, a suitable sump & distributor, and probably new front springs & a small hood scoop.

The former will be easier but more expensive (but could also include stroking since you're buying a new crank, rods and pistons anyway), the latter will be more difficult (more engineering required) but cheaper if you sell your old engine.

distributors are different? how?. To me the 351w option seems easiest, just bit worried bout if ittl fit between guards?

I have two efi engines but only willing to part with my spare, ive listed it in the for sale forums, or to swap for 531w.

5.0 distributor shaft OD is .467", 351W is 0.531". This is the OD where it locates in the block and acts like a bush to stop the shaft wobbling. The oil pump driveshaft hex is a different size. Length is also probably (I don't have one to confirm this) different as the deck height is 8.2" v's 9.5".

No actually late 5.0 shafts have the same 0.531" diamater. It was only early 289/302's(point type and duraspark carby engines) that had the .467 shaft. And it's actually the diameter where the gear is mounted not the pilot hole portion that's below the gear.
5.0's have a 1/4" drive shaft and 5.8's have a 5/16"
The hole in the block for the distributor itself is also slightly larger in a 5.8.

eboost, the fact that you are worrying about whether it will fit means you haven't been listening.

Pete, grab a 5.0 distributor and measure it.... Like I said, the 5.0 has the small diameter shaft where it locates into the block just below the gear. The 351W has the large diameter shaft.

Yes, the shaft where the 5.0 gear mounts is the same diameter as 351W and 302/351C @ 0.531", but this is irrelevant from a distributor compatibility perspective.
