I run a Quickfuel 600 vac sec on my XF ute with similar specs,

if you're getting a mechanic to do the diff bushes, replacing the blade arm bushes at the same time will be easiest, as you have to undo them to lower the diff cradle,

throttle body will be fine

@BTS666 Yeah I put some N50R14's(around same size as 295/50) on my XE sedan, only had around 3mm clearance to the lower control arm & rubbed while moving,

If changed to Lower control arm to a tubular or RHS like then would have more clearance, but would fit a 275 quite easily stock,

Seen BP Swan Hill has removed its LPG tank, not sure on Kerang Shell, they had their tank retested & new valves fitted the other month, but hadn't had it filled few weeks back. but still have 2 in town, & available in most towns around,

I've recently brought a '76 F100 w/duel fuel, but looks to not run on petrol in 15+ years, need to get its 200lt tank retested, while I can still get LPG locally I'll keep it on the effie,

My brothers XE Wagon has had the seat rails redrilled to mount the seat further back,

As I posted on Facebook but will post here as well incase anyone else wants to see wiring diagram,

XE style is MAG pickup, you'll also need to cut the RED looped wire that comes out the box for 6 cyl firing

means power will start declining around 5800, some tapper down, others fall off faster, so possibly peak HP around 5600ish

Valve float is more dependant on valve train & valve springs, my 302C when I first built it made power cleanly to 6000-6200 but after a while the valve springs went softer & if you didn't shift at 5500 lost like 20hp+ by 5700

Yes use the breather hole to fill with oil on the Aussiespeed rocker cover, I have one on my XF ute, 

Pro-Gram makes Front, Center & rear main caps for cleveland, windsor (5.0, 302 & 351) & BBF,

I had a TFI chrome 9x2" filter on my XF for a bit before I fitted new engine as filter stud stripped out of the carby.

at a guess date 8/89 for EA, a EA S-pak I brought had snowflakes.

its a Hall Effect TFi distributor, I know with MSD its common to remove the module & then 12V+ve(ignition), signal wire to MSD, Earth/12V-ve,

& MSD Hall effect uses points pickup wire (White)

I have 1 7/8'' to 3 1/2'' 4into1 Proflow headers & have decent clearance to starter motor, but did add a heat fabric type heat shield just incase.

I have B&M pan & aeroflow braided flexable dipstick on my C4 (pan fill/C10), I added a male to male fitting into the pan, then a female to female 90° fitting, then B&M dipstick adapter, then aeroflow dipstick. Standard pan & dipstick 'just' cleared my extractors, but also know @clevocortina copied my setup for his XD as he had clearance issues,

from memory E1 was same as XD/XE 56-58cc

It was the Accel pump diaphram, just leaked fuel everywhere,

Filter stud had came lose a few times was a bad fit, I was like where did it go... must of fallen on the ground. bit later, knock knock knock. was alright with a new stud,

Piston had part of the stud stuck in it after I removed the head, (RHS of broken section), block looked good & is standard bore so should clean up alright.

I used to have a 6210 650DP, was on a XE V8 parts ute, worked alright but acc pump died, it also killed the parts utes 302c when the air filter stud came lose & went into Cyl 8 breaking the piston. later put a kit in it & fitted to my black ute but started leaking from the plug above the rear needle on the bowl that had been patched before, so brought a new HP street 650DP.

I remember reading something on here about Thunderbird V6 roller rockers once same as cleveland(& big block ford) but 12 in the kit instead of 16, might of been Scorpion 5/16" bolt on...

Crane kit is CR52745-12, I tried this kit on my xflow but had a few guide plates that didn't line up well. Ended up going Yella Terra/Street Terra kit bolted up easy as.

BA XR6T & V8 had T5Z from memory, but have fine spline input shaft (maybe 26 spline) from memory

EFi fuel pressure is more like 40-60 psi N/A, Eg XE EFi 36psi, AU is 275kpa/40psi AU XR is 300kpa/43psi, will need EFi rated hoses & clamps, 5/16" fuel line is a bit on the small size, 3/8" would be better, 5/16" could be used as returnline, not sure on fitting EFi pump to carby tank

2. double check if GT40 or GT40P heads as GT40P had the different plug angle, GT40s might work with normal XDEF windsor extractors, did see a XE wagon with factory 5.0 headers

5. I'd use E series tailshaft stronger tailshaft to diff flange mount,

7. I'd say Terminator X, But to pass engineering may need factory ECU for emissions standards, or may have to pass a IM240 emissions test (heard is like $1200 pass or fail) best talk with engineer on that.

9. EF/EL AU/BA BF/FG Falcon Thermo fans fit XDEF radiator with a bit of trimming on mounts & for top hose, or there are ebay alloy radiators with thermo fans, I have AU fans on my V8 3 core.

Cometic MLS head gasket they are 3.78" bore 0.040"' thick, https://www.spoolimports.com/cometic-ford-250-xflow-inline-6-cylinder-multi-layer-steel-headgasket

Watching The Skid Factory (youtube) I've seen them use heat gun to winkle up the winkle paint,

*after a bit of looking back through your thread, as a temp exhaust, cut through the expanded part on the collector & rotate to the left (guessing 4-7mm) then reweld, should work

Those extractors also look to tapper down to fit in that small "collector" that looks to just be a flared bit of pipe from when they were made,

if so, I'd cut them back where they are still round (maybe extend the secondary's a bit & put a pair of mandrel bends from where you cut) then put a twin 1 ?/?" in to 2" out collector, also with the extractors does the 4th cyl pipe go into the side of the 1st cyl, or is the collector just hidden by 2&3 (hard to tell from photos).

As to pipe size Vs engine as a EG. VE SV6 3.6lt has 2 1/4" twin from factory, 1800cc per bank, so 2" will be fine for a 1660cc.

also to 2" single on 4.1, from memory BF E-gas utes have 2 3/4" exhaust, & EA onwards were always 2 1/4".

Bros ZH 302c, 350 Holley, 3.0 9", got 15.3lt/100km with slipping almost dead C4 auto (with no 2nd gear),

Dissy gear depends on what core is used Comp -8 cams are cast core which can use composite & maybe steel (I need to research them a bit) as where -9 is steel billet that needs bronze which wear over time, or Comp & Crow sell melonized/melonite gears which can be used on different cores cast flat tappet, hyd roller & 1050 soild roller & don't wear out.

@gerg mine is next up 21603, 214/214 510/510 110, Umm fuel economy is hard to say as ute runs 4.11 diff. but did once have 17.8lt/100km, normally like 23lt/100km, also with 4.11's & 2800 stall bottom end torque isn't an issue. . but did notice big pick up in low end when changed from AFD hi rise back to dual plane. As to larger cam & bottom end my XF ute has 237@50 cam & bottom end is just like a stock crossflow till revs raise into cams power range & off it goes, still stock convertor & did drive with 2.92 diff for a while.

I'll be looking at hyd roller for my XE S-pak utes 302c, tho it might just stretch to 393.

I'll PM you a bunch of links, I've got links to older catalog listings.

Yeah have read up to .550" & .560" from various forums over the years, GTHO/BOSS 351 style can go .580", Ford USA actually made a drag cam around 245/256 560/570 back in the day

.490"-.500" lift is for stock springs,
