I have a 98Gt stock at the flywheel they have 225hp.

Now, I hopefully am getting PI heads soon, and after I get those before they get installed I am going to get Crower Stage 2 N/A cams, and aftermarket intake. I already have Flowmaster Cat backs, UD Pullies, and Cold Air intake. Is it crazy to expect somewhere in the neighborhood of 350 crank hp after I do all of this? I hear the PI swap gives you like almost 60hp because it ups the compression too. The cams on a PI engine give you in the neighborhood of 45hp (MM&FF), and what does everything else give me.

So 350hp or no?

The PI heads will raise your compression a tad because they arent dished. You can probably assume 3-5hp more than a 99+. However, that doesnt hold true if you have a high mileage/tired engine anyways. Secondly, depending on those cams, you might need to swap in dished pistons to accommodate the increase in lift/duration. Seeing 45hp through cams with pullies, muffler and an intake is a bit high. If you add the heads, those cams and dish the pistons, id guess your car would put down 260-270 rwhp at best

350hp at the crank is a tall order for a N/A 4.6, 300hp at the crank is close to where you will be

These guys got 50hp out of those cams and I don't know how they did it. I'd like to be at atleast 325 crank hp. Dang.

it's a magazine, they get paid to inflate numbers so the product sells more. if you were FI you can easily pick up 50 rwhp from cams

Mods in my sig net the HP/TQ in my sig. You might see some gains over mine with more aggressive mods but 110 HP is a long way.

They also got 20HP from the Plasma Booster.

If we all installed everything MM&FF tested over the years, we would all have 450hp race cars.
