4.6 stroked to 5.0

sleeper108 · 07-03-2009

alright, so as i am tearing aaway through all kinds of stroker kits on the internet, i realize i cannto make sense of any of it. so i am looking for some help my friends.

I was wondering what all has to be done to make an engine capable of handling up to ~600 hp

how do i stroke an 4.6 to a 5.0

how much does it cost? (i dont know all the parts that are needed, pretty much, i know that connecting rods, pistons and a crankshaft are inorder, but after that i am lost.

thats for everyone in advance. eventually i would love to start tearing into my engine, and create a beast. i figure now would eb the time to start teaching myself.

you need a 3.75'' forged crank,forged h beam rods and forged pistons.get a kit.

im sorry if this is a stupid question, but i simply do not know.

is it the size of the crank that will determine the displacement?

any particular brand i should look for? i understand livernois is a good company. im assuming they could hook me up?

eagle makes some too im not sure how good they are though

You are going to need a blower to make that kind of power. And there are only a few that will do it without a lot of trouble. The KB, Procharger and Vortech come to mind. Going the blower route will require you to get forged internals for the shortblock. You could get a stroker, but strokers technically weaken the block because of the removed material and the different loads placed o it because of the geometry of the stroker crank. The good news is that making 600rwhp is a piece of cake without stroking the motor so you can have your cake and eat it too.

Why go stroker and add potential problems when you can make 600hp with 4.6L with no trouble at all?

Besides, you are going to be spending a fortune making 600hp anyway, no need to spend money you don’t need too.

good to know, i was under the impression stroking it would make life a little more simple.

i plan on F/I far down the road, since i rarely have much money to play with. But when i do go F/I i am looking at the Powerhouse turbo system.

so scrapping the stroker, just forged internals would be alright? they all ask for bore and information that i have no clue on. which is why i am asking. (i think i was combining stroker and forged in my mind)

Well 600 shouldn't be a big deal with that.

Plenty.

Who asked you for the bore of a 4.6?

If money is an issue Stroking it wont be cheap.I think people are assuming that a stroker kit is some simple bolt on part. There is a ton of labor in stroking your engine.
Also stroking the engine wont make the car a 400hp monster. You will need heads, cams, and other boltons to get to 400hp.

I say it again. A blower will be the easiest way to get big power out of these cars. There are many people that are running lower boost levels on stock internal engines and alot have lasted many years and track runs.

Bore is 3.55 in. Stroke is 3.54 in. in our 4.6 engines.

i may be getting confused yet again, but it says .020 over?

NVM! i was looking at livernois' 4.6 4valve, which said .020 over.

New - Livernois Motorsports - 4.6L 3-Valve Standad Rotating Assembly

that one has the option for .020 over, is there any point in this? or could i just get the 3-Valve Roots/Turbo 9.1:1 Compression Rotating Assembly, and call it just as good?

i never expected it to be cheap. i planned on saving up for the engine internals, and then hopefully in the next couple years, do the turbo. I have some rather short term goals of hitting 325 after i do exhaust and all that (in anticipation for the turbo) but dont really plan on creating a monster for quite some time.

and want to get forged internals before i do boost, since if i have the itch, i can just turn up the boost with no worry of destroying something.

.020 over means that the bore has been increased by .020 inches. If you are going to build an F/I enginge you will wont to keep compression down...just in case it hasn't been put out there for you yet. Personally, I would go with a stroker kit and increase the displacement. Its a minimal increase in cost and you are already going to tear into the engine anyway.

sleeper108 · 07-05-2009

so, going .020 over in anticipation for turbo would be a good thing. correct?

your best bet without a doubt would be to buy a shortblock from say MMR or livernois and then look into F/I later down the road. Actually now that i think about it do forced induction first would be best. You can run a safe tune and make 400rwhp which will be like daylight and dark for what u have now. Then later on buy a shortblock from mmr or livernois and bolt that same blower on and then turn the boost up and make 800 hp if want it.

hmmm that sounds like quite the plan!

sometimes i wish i just had another 20k to play with this thing!! ohwell, seems that will take quite a while.
