Hi all
Now here is a serious question that will certainly create some debate.

Headscratching with the Mav. I really need to stop reading up on things.
As part of the rebuild of the Mav I have got myself a low km AU Series 2 175kw motor form a Fairlane. It will be running the full AU ECU and coil packs etc which will be tuned by a Quarterhorse..
I also have myself an Eaton M90 blower thanks to SWC and have seen what they have done with them in the states on the Explorers.

I am handy with the welder and the spanners so making manifolds and screwing motors together isn't a major hassle for me.

I am after a nice torquey motor for towing my camp trailer easily , but also for it to sound tough and go well enough to keep the drive to and from interesting with Sydneys P platers.

Basically what do people reckon will be the best bang for the buck. Build a 347 bottom end or fit up the Eaton?

I have spoken to my engineer and he has no issues passing the charger providing I can get it quiet enough and pass and emissions test. I am confident both can be done.
The truck is already engineered for the 5.0 that is currently fitted.
This is where I am scratching my head.

Remember Im talking bottom end only here as heads and cam would be done on the motor if a charger was fitted once it passed its emissions and enginnering regardless. I see it as the same cost both ways.

Being realistic by the time I fab up the manifold for the M90 and get it setup with a water to air intercooler , quiet exhaust with a 400 cell cat to pass emissions and have it engineered on a stock motor I cant see any change out of $3500 roughly. I understand that technically the M90 isn't big enough for a 5.0 but for my purpose it should work ok.

Then there is these 347 bottom end kits available.

I have a contact for machining and balancing and can screw it together myself. Once I get the kit , do the machine work , buy oil pump , studs , girdle etc I will be up around the same money as fitting the blower BUT would have a fresh bottom end and no requirement to do any further engineering. I also have the option available of buying an already built 347 bottom end from BG engines for $4k with a 12 month warranty.
One thing that is not negotiable is the fact it must be engineered. I wont do it any other way.

Because Im getting married next year , unfortunately doing both the blower and a stroker isn't an option. Its one or the other........................

For what Im after whats the collective thoughts of what I will get better results with for the dollar?
Cheers

Depends how you mount the blower? Is it a short snout Eaton you have?

id go blower.

Id go bottom end. Can always find the funds later for a pump. If you end up not being able to charge it at least you still have a stout 347 to haul the truck.

Pete it would be a valley mount.
The charger is one of the M90 from the 3.8 Mustang so the snout isn't super short but isn't massive either.

M112

lucky you got height, once you clear injectors/rails the blower sits up pretty high.

That's what would end up on it eventually if I go the blown route. At this point in time it is not an available option but.

Ok Matt, that's going to be a fair bit of work to mount only to have a 90ci blower.
If you going to do the work I'd at least have a M112 from an '03 Cobra(not the Lightning one).
So, knowing these things, I say go the stroker.

Stroker with forgies, then you can boost it down the track if you so desire.

Wait for my motor to be built, take it for a spin the the TE and then make a decision based on have I picked up enough torque for you to warrant going down that track yourself.

Its only 5 weeks away now!!

I also owe you a spin of the fordrunner after its done. Maybe that might sway you in another direction.

The blower will still happen.
I just need to get my head back in a happier place once this injury and possible redundancy is sorted out and get back into it.
Hopefully it will be all sorted soon.
