Not sure mate, I know the AU headers will squeeze into E series as that’s what I did selling them off to a mate with an EB, he also put the gt40p heads on too.

Yep it’s the same intake manifold for all
AU V8 (except the fancy tickford ones fitted to the 5.6)

Nothing off the shelf due to the spark plug angle, however I have Hurricane 4 into 1 headers and I had them fitted to GT40p heads, you would need 90 degree spark plug boots from memory to help them from hitting the pipes.

Those headers you have won’t even come close getting into an X series, been there and tried haha.

If you can find the articles relating to Dick Johnson’s Pine Pac mustangs in the 80s they are a good read on how he managed to get 380hp from the asthmatic 302w back then.

Factory AU LTD manifold


Sent from my iPhone using Tapatalk

I’ve seen some really cool builds on the net for the little Windsor, one liked the most was:
Dart block 4.125 bore
Steel 302 size crank
Alloy Cleveland style heads etc
Big roller cam
Comes out at around 330ci

Made just under 800hp on engine dyno. Wasn’t street friendly.

Anyone know the bore and stroke and in a Ford 5.0 V8 supercar? I’m thinking the biggest bore possible around 4.185 and a stroke of 2.8 inch or similar???

They aren’t factory on an LTD low spec, they came with horrible pinch tight shit manifolds.

Cleaning up the exhaust side is where you get good gains on these heads.

You can get four bolt pulleys, I have a set. The issue is that there’s different depth water pumps and balancers, is getting them to line up is a pain. You can get spaces though.

That’s why I run a gilmour belt.

If I could ever build another Windsor it would be pretty much what I described above.

There is a local factory Boss 302 is a street/circuit car has drag raced it a few times,
Have thought a few times of getting my bros spare 5.0lt, basic reco with 230°ish cam, some Aeroflow alloy heads or AFD alloys, air gap or victor jr & maybe some nitrous...
another idea was Aussie Speed Boss 302 hi rise to suit 2V Cleveland heads, & SRP BOSS 302 piston to suit Aussie 2v heads (302C closed chamber) 3.5cc dome,
As for porting I brought a Makita 240V 1/4" die grinder (GD0600) & a long shank burr, heaps nicer then waiting on the compressor to try & keep up with my bluepoint die grinder.

last night i was trolling thru you tube and found a video on this rare boss 302 engine and assorted full factory race parts,very interesting video with so many nos parts in boxes ,like the CROSS BOSS intake,plus 8 autolite  carby trumpet stacks.

Not that special nowadays...... 4 bolt mains, screw in welsh plugs, 7/16" rocker bolts etc. Can all be done in a machine shop, but, obviously without the bragging rights.
 
Would be nice to own one, and sit it in the corner of the shed, and stare at it. 

I know of a made up boss using 2V Cleveland and 302w bottom end in an XY.

Runs a toploader and a 9 inch, made 290hp at the wheels at 5500rpm.

For the money you would spend on setting up Cleveland heads you could put some Trickflow 11r Windsor heads on the 302w for probably less money and have more power.

Just reading about the 302 boss from 1969/70, rated at 290hp at 5200, great advertising by ford to try and pull the wool over the eyes of the muscle car haters and insurance companies back in the day, that motor could spin to 8000.

just looking at boss 302 alloy heads agghhhhh,,,

200 is definitely none too shabby, earlier Windsors I think were in the 150s, 351Ws maybe high 170s, 4V Clevos were up around 260. 2Vs aren't as good as you think, I believe Aussie castings were in the low 180s. US ones around 200. I think our casting methods and bowl work left much to be desired on our 2Vs. I reckon mine being very mildly ported puts them up around the 200 mark (of course not tested).

I can see why GT40Ps were sought after in the day. Sort of like how Vortech heads are to Chev guys... Cheap, factory made upgrades.

From the factory they have 155cc intake and flow a tad under 200cfm at .500 lift through a small 1.85 intake valve.

Which isn’t too bad really for a little factory Windsor considering a stock 2V Cleveland head flows the same.

The issue with the gt40p head is that it is good for about 300hp if you bang in a bigger cam and some compression.

I did look into building up a set but bang for buck it wasn’t worth it and I went alloy.

I have a real liking for the little 302 rollers.

there is soooo much stuff to browse and get carried away on,with these late model smallblocks,seems a good upgrade for the gt40p heads is a trickflow valve spring kit,shims and locks,and some other stuff.

Most bottom end parts are cleaned ,block is ready to paint soon
