Stroke or do up EB 5 litre - Ford Forums - Mustang Forum, Ford Trucks, Ford Focus and Ford Cars

Hello all, i have searched the windsor tech, and couldnt really find the answers, so i just thought i ask these again.
my mate has a stock 5 speed EB XR8 with 200'000km on the clock.
he's got 4k to throw at it now.
what would be the best way to get the most power out of the 5 litre ?
he is thinking of getting a eagle 347 stroker kit. What work to the block is needed to have the stroker fitted ? any machining needed to the block ?
or is he better off just leaving it as 5 litre and get better heads ?
someone else did mention him getting a F series 351W, will that fit in a EB ?
any recommendations for his budget would be great, thanks.
Luke

Hello Xr8fella I Beleave The Block Requires Machining To Allow The Crank To Spin Freely.also I Seem To Remember Reading Somewhere That Some Of These Cranks Had Reliability Problems So Research Tour Crank Choice,personally I Would Go For A Supercharger.

Yeah the block generally needs machining to fit the stroker kit, to give bore to rod clearance. $4k really isn't going to come close to building a reliable stroker engine, you may get away with a very basic stroker but IMO tell him to keep saving and do it properly in one hit, or if he wants to do something now throw on some decent heads and an intake and then go stroker later. The 351w can fit but takes a lot of work and also a lot of money.

As EX COP said, I would, and just have gone supercharged after researching both options.

ok, thanks for the responses guys.
is supercharger an option for 4k tho ?

I Dont Know Really ,i Would Think That You Would Have To Plumb It Up Yourselves. Edxr8 Is Supercharged He Would Have A Better Idea On Prices. But Like He Suggested You Could Always Do Things Now To Benifit You Later.

I went the other option of stroking first.
TFS heads etc etc 321 rw/hp.
Now Im looking at Blowing it aswell.
I wonder what ill gain this time....... Heres to finding out

i have given him this info, he wants to just keep it as is , and get it running a bit harder. What ya's reckon he should do ? heads, cam, intake manifold, chip ?

To be honest, stroking a motor with E7 heads and a HO manifold would be a major pain. It has allready been proven that the heads are already asthmatic on a 302 - the extra 45 cubes just increses the problem substantially.
For a first step I would look at cam, rollerrockers, bigger MAF, K&N or BMC filter and an AU snorkle. Removing the clutch fan and fitting a Batterns module to control the Ef/El thermo's is also a good mod.
From there - the heads and intake have to go to make any serious power. We got a good price on a TrickFlow kit (complete street heads, rollerrockers, headbolts, stage 1 cam, timing chain, gaskets, pushrods and Street heat intake) for around $4400 landed. These are good for 350Hp 370ft/lb tq with the right gear around it.

Imho I wouldn't spend too much on rotating assembly..Not much point in having rotating assembly twice as strong as block...
Heads, inlet, maf, 1.7 r.rockers and throttle body first...
