Sydney speed supplies sells 347 stroker kits for 1350.Does anyone know if these kits suit fuel injected windsors?????

cant see what else it would suit. 347 is pretty much the standard 5.0l stroker kit

Id also consider a 331 stroker kit for the windsor, less problems with pistons & rings.

If I took my AU1 5.0 out to 331, would I need new intake/ECU etc, or would the flash tune be able to tune it so it runs well as a 331, with no other intake mods (note, I already have 1.72 RRs, and 4-1 extractors, but no head work).

It would run fine mate, with all the factory stuff, though, a retune and a cam swap will make it better.
But for all the work, you might aswell plan it well and do other stuff to it while its apart, unless your happy to just increase the cubes and nothing else.

I think mine's heading for a rebuild soon anyway, so if I can get a kit for $1500, plus cam and tune for about $2k, then find someone to fit it for nix, it's probably a cheaper way to go than reconditioning the existing motor with stock parts, or even getting a good used unit from FTG or trading post or whatever.

In a way I guess I am just chasing more torque than anything, and have heard that the 331s are torque monsters (but then so are 347s).

most stroker kits are 28oz imbalance, where the 5.0's are 50'z....
so you'll need a new harmonic balancer and machined flexplate.........factor at least 1000 for balancing the stroker, machine work on the block for clearancing / 030 overbore.
then everything else you need - like cam, valvesprings,roller rockers, maf,injectors,main girdle, timing chain set. etc
the $1300 stroker kits start to become not very cheap.
people think that...hmm...stroker kit is 1300, shouldnt cost much more than 200 - 300 bucks and its fitted........its really not the case

Could be suited to a carby engine thats why i asked, im unsure of the differences between carby and injected stroker kits if any at all. you dont need to go too full on with hipo parts if your not chasing more than 400hp. So does anyone know if they suit carby or injected?????????

It will suit any induction system that you put on it the stroker kit is basically only the bottom end so you can put whateva heads, manifold, carby or injection system to suit a 302 windsor. But because you put this in the AU section would i be right in saying its going into an AU and it will be injected.

A carby in an AU? i wonder how the EPA would like that lol.

he was asking weather it suits an old windsor or late as well......
so im tipping he wants to know so he can use it in his injected motor.
yes it'll work in a late windsor...

what brand crank/rods/slugs are in the kit?

the things i said to do in my earlier post should be the same for just a cubic capacity increase or for a hipo motor...........you really need to do it for the longevity of your motor

Why stop at 347? From memory you can take it out to 388 ci.

LUXO_8 · 26-11-2006, 05:09 PM

nop....not a 302 windsor......347 is the max...

angryboy · 26-11-2006, 09:28 PM

I saw the ad in the new street machine, rpm usa cast steel crank, rpm usa h beam forged 3d rods,flat top hypereutectic pistons,race series thin groove rings,main, cam and big end bearings.full felpro gasket kit. I would love to build a 347 for my au. apart from machining i can do everything else my self so i reckon that i could save a bit on labour, wots this i hear about problems with piston clearances with valves, did i hear right beacuse my memory is really bad[ i have CRAFT]

For all you blokes thinking about stroking your 5.0 litre, may I suggest a book for you to have a read of. How to build big inch small block fords by George Reid, about $40.00, at your local automotive bookshop. Should give you all the info you require. Hope this helps you all.
