With that crack she is cactus bro...You need to re block it.No saving that.Make grout your friend and when assembling be very particular with the tightening sequence and use a lube and sealant on that front stud.

awesome bro...

Yeah your right Jase my slapper ute engine all them years ago went from a engine that struggled to rev to a clean revving better running car instantly.There's a thread on xfalcon people should read before taking any advice off that mentioned bloke.

So for my last side track of Marks thread...When are we gunna see some of these engine you helped your mates with bro.I'd be interested in seeing em and how you work as we all can learn off each other still.Keep all your secrets but a basic run down with some pics will re-enthuse some of us.

There it is...even Q admitted it,Wes has dealt with it for ever and Ants can vouch for it with his yard.I was like this in the start and to a degree still want everything as cheap as I can get it but there is no getting around buying solid stuff when you want to step up with the really fast boys.Over $1000 for 6 pistons can make you question if your on the right track when you look at Windsor or Chevy units @ $600 for 8 but the outlay is a necessary evil of going fast with a NAT ASP 6 banger.No one ever said going fast was cheap or easy no matter what engine it was...unless it was stolen I guess? Cast pistons and hyd cams on stock rockers in stock bottom ends just don't cut it.A x-flow needs a investment if they want em to go really fast and Marks products are all worth the money IMO.I do have different expectations and goals than others do so I can accept my views will be different to many also but at some time common sense needs to come into play and people need to realize the need of outlay for results.

Good on ya bud...bet the old bloke would be proud of the effort.The bonus is you get a killer looking XE.

Ummm yeah I wan't to know this bit too...?

Atleast I return ph calls Yes I know being different costs money but why run 10's and be boring when I can run 11's and be cool? I'm not expecting too much from mine just want to smack a few V8's and snails along the way...LOL About to order induction parts this week too...perhaps which will leave me with a spare Aussiespeed 4barrel manifold funny enough.But I will save it for my spare petrol engine LOL Still stands that people expect to pay twenty cents for performance parts when it's for a x-flow but a V8 or turbo they will pay thru there nose and ass? I don't get it bro?

And there lies the single biggest issue with 99% of X-flow owners.Most want $10,000 performance for $10.It just doesn't work that way.I know there basically a old tractor luggin snot box of a thing but performance parts cost money and alot are custom made or a "found" item from another brand or make that just happens to work. I have a custom girdle custom pan,custom stud kit,custom guide plates custom pipes and the list goe's on and on.If it was a SS they would not think twice about dropping $4000 on a set of wheels and another $4000 on a stereo but god dam if they will spend $400 on a manifold? We need to get people out of that way of thinking and accept if we want to go fast we have spend money on needed parts even if it is just a old tractor engine.

Well I have yet to hear anyone complain about a TFI dizzy plus MSD ignition on a xflow.Starts easier,better fuel burn for more power,better economy if tuned to suit,smoother driveabilty and all for under $300. What else would give you that return for that sort of money?

Two blade screwdrivers resting on the dizzy body to lever it off.If your concerned sit a rubber sleeve or cloth over the plastic but it should come off easy enough.before you fit the new one wipe some anti seize/high temp grease on the shaft.Not much just enough to act as a lube...

Hey mark long time no see...Welcome to Ozfalcon. Some good info there bro..

Like I thought...

Ah ok Alec would have done it for sure.

It did have a oil change after start up run in too didnt it?

It comes down to how much you want it to last and how much you want to spend bud.PM is expensive but it lasts waaaay longer. Look up PM lubricants and make your own mind up bruz.

If its a fresh engine lighter weight is needed cuz.I use straight PM 50 which sounds thick but is actually rated at 20-50.PM doesnt break down like others and has a loooong service life.

factory webber takes around 3-4 psi from memory

Yeah that dude on xflacon did it bud...macdaddy or something his name was and he was from ACT.

I could do 1 but have found 2 very competent and keen fabricators to do the job for me instead.Still the basic idea is there for 1 throat/tb per inlet port.Taking that thinking it's easy to sort many combo's that could fit that bill.The chosen fabricator has ALOT of V8 supercar experience so has had to work within alot of restraints which gears one for problem solving via different means out side the normal.Braddy had 3 XF webbers or strombergs??? on a custom manifold that appeared to work on a stockish engine.Not hard to improve on it... That only leaves the exhaust as your weak link and as mine is getting custom merge collectors and a twin 2.5 exhaust I feel that is covered now aswell.Again not everyone's idea of what should or will work but after talking to the right exhaust shop and head porter/fabricator it seems it is going in the right way.Issue here is mine will be very very far from a daily but if reworked via smaller camshaft (even hyd),less compression and petrol and a rethink of the exhaust to quieten it down I bet it would run very good numbers and be happy as a daily aswell albeit a tad thirsty as you would still spank other streeters on the way to work for fun...LOL If we remove the "it can only be this way" thoughts from peoples minds we can achieve much more all while seeing the issues raised as simple engineering/mechanical problems like we solve in other areas of our lives on a daily basis.We just have to aim for higher efficiency with every single aspect of what we do in modified engines or stick with what some claim is the only way and watch the rest go ahead. A boosted engine is much softer on engine components other than pistons and valves springs then a NAT ASP engine is due to the constant pressure on the rotating assembly acting as a cushion if you will.Where as a NAT ASP is continuously loaded and un-loaded on every stroke which is why we see certain conrods last in boosted combo's that can't in a NAT ASP deal.NAT ASP is HARD on a engine thats near the limit yet boosted engines just swallow more and more.They always have a safety window ready to go like a head gasket where as on a NAT ASP combo it will be a conrod out the block or such.Tuning is the key to reliable boosted combo's,even NAT ASP really. The factory BBM manifold off a E series seems to be the go for boosted x-flows but even the stock unit can make REAL numbers judging by that green one that came from down south that young fella did.Boost will flow anywhere but vacuum needs help to flow well and be efficient...

Speedway boys use/like the EA manifolds for that reason bro...Even Holden 6cyl manifolds have different port sizes shapes to try to create more even flow into the head.We basically have a very poo manifold to deal with and the OHC engines really sorted that with there EFI set-up but as for us with carbies you have some trouble.As good as the A0016 Aussispeed 4 barrel is it's just the best of whats available really.It will make awesome HP and is cheap for what it is but it cannot be tuned liked a individual throat/TB per port can. I know "some" people think otherwise but after all this time and still praising the single 4 barrel on a x-flow amazes me.Marks manifold is very good and maybe too good on 1-6 and I know Jase had good success moving the carby on his Cain sytle manifold to help fix the issue but thats beyond what most are willing to or want to do with there's. I can show people mine when it's done that is VERY left of field and VERY custom but it could be done in soo many different and cheaper ways it's not funny.It really makes me wonder why it hasn't been done before or maybe we just havn't seen it or looked hard enough or didn't pay attention? Webbys Webbers make the point loud and proud and it's easy to see why when we open our eyes...

It's all in the head and reversion and extra flow on 1-6 ports due to vacuum.It's unburnt fuel caused by the POS manifold hanging off a xflow head trying to feed 6cyls.Which is why a xflow head flows like poo cos you go and fit a POS manifold to it.If it had a straight throttle body or Webbers well no issues but anything less than that or boost will suffer.Common sense tells you that...1 carb with 2-4 barrels feeding 6cyls with different length runners and different flow rates? Please come on? OK that said if used for wide open constant RPM it would be fine but up and down everyday driving IS NEVER going to be your friend. Again I think you have my number if you want to talk about it bro please ring and I will try to help as best I can...I know Jase had good results moving the carb but I don't know your limits or intentions either but will try to help if I can. Rob

Nope uneven cyl fill is all.You can try moving the carb or go webbers or EFI or other means. I know which way Im going.

Ill call you tonight bro

I have a issue where I need to shorten my BW diff about 50mm each side.Now a mate has 2 small bearing XY axles he will give me if needed but I'll only take em if they fit my needs.So basically do the backing plates and all that stuff fit and can I keep my current disc brake set-up as is? I ll go ahead and shorten the diff to suit the new XY axles instead if there gunna fit in there no mods as it would save me having to get my current axles cut and resplined to suit?
