Is there any one out there available to give us the low down on running these motors in Superstocks..I would be really interested to read about them.....cheers mike jansen Z

I did a fair bit of research on these motors when I was thinking of doing a superstock.

Torque wise they are a hell of a weapon - even standard they can pull better than a school boy, delivery is pretty linear too so its pretty well suited for a superstocks get up and go requirements.

Ttheres a bolt on manifold from aussie speed that will fit a quad barrel holley, heres the link = www.aussiespeedshop.com/product/ford-barra-dohc-4-barrel-manifold/

Carb wise, Holley is always easiest - 650cfm will be almost too much - but with the high rpm these things put out in standard form {somewhere between 6000rpm and 7500rpm is were a standard engines rev limit should be, head lifts at 8000rpm} it may suit better than others, 390cfm is the lowest you want to go purely because as time goes by you'll want to increase what the engine can do and it will eventually be limited by the carb.

Ignitions is a pregnant dog. No dizzy means either MSD or Electromotive would be the way to go, I would favour Electromotive though as it fires a hotter spark and gives a better burn - a slight increase is power there.

All bolts up to an AU falcon bellhousing and your all set to go.

Ignore the people that say "you gotta have over 400hp or you'll just run into trouble", turns out thats a load of round things. if your setup is right you will find that they struggle to catch up to you purely because they cant put the power down - turns out theres such a thing as too much hp and its a surprisingly low number!

You are right. I tried this out a couple years ago with a stock standard motor straight from a road car in a little flat chassis. had good power. 390cfm double pumper holley, electromotive ignition and just wanted to see what it went like. Was good until at about the 9th meeting when it pulled 8200rpm and lifted the head. There was also one built in rotorua that had engine work done and ran a link computer that went very well also, think it got parted out and the motor is in a road race car now. I have thought about trying this again in a newer chassis. Certainly a cheaper way to go.

Hey

So just wondering if you had a stockcar running a ea onwards engine. Would a BA engine bolt straight upto the firewall? Or is a new fire wall needed?

Thanks

its the same bolt pattern - shouldnt have to change firewall in anyway - should even be able to use an a or e series girdle too if you used one with your last engine.

Its a drag and drop switch from any e/a series to B and F series engines.

[shane878r]

they wont bolt into any falcon powered stockcar, you need more room at the front as the head is long over front, and you will also have to notch the top of the fire wall to allow where the head over hangs the bolts, if your firewall is nice and low you wont have this issue, clive pritchards ba made around 410hp at the wheels, had heaps of tourque, and was under half the cost of a nissan or toyota v8 with similar power, ring terry o conner in rotorua if your after info on them he knows everything about them

So could you run 1 of these motors carbed in a limited saloon,havnt got rule book hence the question...

Unfortunately no - its half a litre too big to fit the rules. can run one in a super though - would go good if you turbo or supercharged it.

An Au would be fine though - its not got the twin cams though.

[rangi]

Isnt zach lawerance 22b running 1 of these in his superstock?

[mobilechicane]

intertesting, what needs to be done to stop the top blowing off at high revs. got a real nice motor here with an honest 107km...so smooth shame the tip tronic box has gone haywire,,with a replacement car coming soon no point spending any money on the falcon...those BAs started life with an AU bottom end, will be some round could take a dizzy dont know what it means for the twin cams though...grunty motor at revs,,,bugga just wont pop into 4th...but ya get to see how she loves to rev in third lol

[Deleted]

At a guess I would say o ring the head and block - put in some tougher head bolts. that should sort it out.

in essence though - you shouldnt need it to start out with, the ford six is a helluva lot tougher than it gets credit for and replacements are pretty cheap and easy to find. set a top end rev limit at 7500rpm and your gonna be fine, once you start doing some head work then yeah ok - maybe then you should look into it but not straight outta the box.

[mobilechicane]

so what is this O ring bizzo about?

[Deleted]

well basically o-ringing the block is simply having a thin copper wire placed around the bore and glued in position before putting on the head gasket and head.

In theory it supposed to press into the head gasket and make a better seal and improve horsepower handling - doesnt work for every engine though and I doubt you'll see alot of engines around nz that have had it done.

If you simply replace the head gasket with one from a xr6 turbo head and put in some seriously tough head bolts torqued down properly, then you should have no problems anyway.

[mobilechicane]

yeah was reading bout it last night, pretty simple really for a machinist, go studs instead of head bolts and upgraded gasket do you want new cam shaft specs too, anyway once the head is taken care of, what do you rekon the neck issue is?lol

[Deleted]

always want new cams, put vernier gears on them - alot lighter than the system the standard cams come with.

after that your looking at bearings, rods, pistons and piston rings. usual upgrades over time there.

apparently the stock crank can handle a whopping 600hp with no problems, its the rest that start to give out.

[The Observer]

So has anyone noticed a BA Falcon from HB had a 2nd in the feature at PN on legends night, and recently had a 2nd at the HB superstock champs in a top feild?

And you can pick up a stocker for 600?

Has this motor in 22b had the big superstock dollars spent on it, or is it a legit alternative at a reasonable price to the big dollar v8sbout there?

Just seems to get better and better. Hopefully we see some in car footage soon

[Deleted]

thats the Demanser superstock isnt it? thought that was a worked nissan engine...

Although we're still down on power compared to the big dollar V8's, the 6 has proven in the last couple meetings that on the right track conditions we can run with those cars.
Its definitely not a big dollar motor either! We built it ourselves in our shed at home after alot of research!

Nope, Home built chassis new 2 seasons ago!

way to go dude - looks like your proving what Ive always said about the big six!
