Wondering if anyone has it and how worth it it really is and how much expected hp gain. I
Plan on putting a whipple on aswell just wondering about this for now. Have long tubeS,throttle body, cams, intake, tuner , gears pretty much all bolt ons if that matters. Just wondering if anyone had any input on matter

If you're going to build the lower end which is what a stroker kit entails and not supercharge you're wasting your money. You'll still fall short of the cheapest SC kit and it will cost at least twice as much. Now if you're going to put a forged bottom end in aka stroker kit and SC then the sky is the limit or your wallet is. My buddy is putting 680hp to the ground of his 3v 4.6 on 93 pump gas reliably and consistently.

Def plan on doing both,def got a limit on the wallet lol but I wanna do it right, so your saying supercharge it first to get the most power then add the stroker kit after

I am saying you have two choices. Spend $3500/$4000 get 450rwhp, live and drive happily ever after. Go for 600rwhp+ spend $20,000+ and work on the car constantly have over heating and breakage and drive the car very little. Your choice.

Well the choice is apparent there. But you make it sound as your buddy has 600+rwhp with a reliable car and no problems. I'm def going the blower route just needed some input as far as adding the stroker kit or not. Bottom end could use some work but not at the extra 10k

My buddies 700rwhp car cost $100,000 not $20k.

****! I might have got a viper

Love my stand as much as the next guy, putting every dime I can in her but 100k is a lot. Actually it prob get a gt500 and mod it. But to
Each his own. Ill be happy when I get my supercharger on. Any recommendations for good street slicks?

If your going to stroke it, the best bet is to get the biggest bore with the shortest stroke - however you get to 5.0 or greater displacement a bigger bore is going to make more power since it allows the heads to flow better but that may entail going with cylinder liners which gets pricey.

The other and cheaper direction is to marginally increase bore size while greatly increasing the stroke which yields little in the way of improving airflow.

Its a shame Ford didn't include the oil circuit for the 3v VVT system on all its MOD blocks and more parts commonality, the current 5.8 block in the GT500 would make for a sweet build in the older GTs, IIRC its the largest bore (by a whisker) V8 Ford makes along with some serious stroke to get there and with almost 75 cubes (I think its 355 CID and not 351) that'd make for a worthwhile increase in size.

Ultimately with a positive displacement SC the size of the supercharger determines the amount of air it can pump and therefore the HP. doesn't matter much if the engine if 4.6 or 5.4. The M122 makes the same power on the 4.6 as on the 5.4 with slightly less boost because the CR is higher on the 4.6. But ultimate numbers are meaningless because of the money involved. 450rwhp for $4000 not much can beat that money wise and no point in spending more for a few more HP.

Why spend 20k+?

Ive seen a video of a 4.6 ( 2v,3v,4v ) gets boost demo, THE 4.64v was a create oem factory engine, with some internal upgrades , done on a engine dyno .with twin to4e-57mm turbos, achieved 20psi of boost they were reaching the limit , either the cold side or the hot side and on E85 fuel run a pull 990hp..
