So I lost a piston on my current motor and have some idea for the new powerplant. Looking for some input.
I currently..well was..running a built 2v vortech motor, pullied for 12lbs boost. I am tired of the mess that the vortech makes with belt slip and overall I just haven't had much luck with it.
I don't drag race, more of an track day guy, I like my shift points around 5500-6000rpms. I am open to an occasional on3 run here and there if a sensible opportunity presents itself.
The whole car is built and can handle damn near anything I throw at it.
5 speed, 3.2 dumping rear end gears.
So with that, this is what I have in mind:

Ford boss 50, 3.7 big bore block
Forged stroker rotating assembly, 23cc dished pistons for around 9:1 compression.
Keep and refresh my built stage 2 ported PI heads.
Run my current stage 2 Bullet blower cams.
Full exhaust.
Top it of with a kennel bell 2.6 running 14 lbs boost. This will give me room grow if I want.
I also have meth injection that I run.
I'm looking for street able 550-600 at the wheels and really want the seat of the pants fun without have to rev to the moon.
I want this to be the last time I pull this motor so reliability is key.
So any thoughts are welcome.
Overkill?
Thanks ahead of time.

why not just replace the piston and work on the belt slip ? Stroker and big bore isn't going to give you any more power as your limited by the heads.

600rwhp is going to require more than 14lbs of boost on cali fuel. Best bet would be E-85 and 17lbs or 22lbs on the 91 which isn't advisable.

Umph...I kinda really hate the vortech. Kenne bell 2.1 on a refreshed motor? I don't want to go 4v, cause money money money.
Maybe 450 at the wheels?

Compression check 7 cylinders
125 with thottle closed. Seems low

why not just fix that one cylinder? Seems like it would be most cost effective get you back on the road the fastest and being that all else is fine you shouldn't have any reliability issues.

I'll check it when the engine is out.
What's your thoughts on the kennel bell.
I been fighting with this vortech for years. I'm just sick of it.
Thank you for the follow up

I always lean towards whipple and procharger.

Thank you Michael.

Even though I run a Kenne Bell 2.1 I only suggest thier blowers as a whole to people who have 2V cars and need to deal with emissions. This because it's the only smog legal PD blower available for the 2V.

If emissions isn't a concern go Tork Tech and don't look back. Judging by your eyeballing of the 2.6 I assume you're not worried about emissions testing.

Why tork tech instead of Kenne bell? First off going Tork Tech will give you far more blower options and potential. Want to upgrade down the line? No problem just buy a bigger blower. With Kenne Bell you'll have to buy an entire kit because they don't want people to simply upgrade.

Lastly I could go on and on about the quality or lack there of in the Kenne Bell 2v kits. Yes Tork Tech has problems too but don't be fooled into thinking Kenne Bell is better. That 2.6 manifold is just a modified 2.1 manifold as well, it's nothing special and the casting itself is by no means close to OEM. It also has an issue on the passenger side gasket surface that Kenne Bell hasn't fixed.

Go Tork Tech.

if your going to swap to blower then swap out the heads for a set of trickflows. Thats an easy +200rwhp bolt on for a blower car.

Be sure you get the tfs-44 heads and not the tfs-R heads which require a big bore.
