BMW
Why have a V-8 that doesn't deliver its peak power -- 414 horsepower -- until a dizzying 8300 rpm? "When you drive on the limit, a higher revving engine allows the driver to more finely adjust the torque to the rear wheels," says Richter. "It gives more sensitivity." Peak torque is only 295lb-ft at 3900 rpm, and the delivery is so linear -- 85 percent of that figure is available across a 6500 rpm rev range -- that the engine just doesn't seem to punch as hard as a you think a V-8 should. The sensation is deceptive, however: look down at the speedo and you'll almost invariably be going 10-to-20 mph faster than you think. On almost any given stretch of twisting blacktop this M3 is 911-fast.

RE: Horsepower TV
I'm well aware that a Supercharger/Turbocharger/Any other forms of Forced Induction are capable of giving me more HP and bang for my buck. I'm happy with my 300 RWHP, but just want a little extra. I'd also like a stronger motor that I can potentially rev a little higher 7000 RPM +
I'm not a fan of Forced Induction however, I know it's great but I like being all motor. Plus this project will eventually be something I tackle on my own; minus any machining work. It's very enjoyable and as long as one does their research and takes their time; anything is possibly.
The car is just meant for street use and to be a fun all around car. I don't plan on autocrossing it or frequently drag racing it. I think with a HIGH Compression engine with aggressive cams, and P&P heads along with a ton of other bolt ons that it will achieve 400 RWHP, or close to it. If Horsepower TV can get 375 RWHP. Just think what a little more compression, more aggressive cams (I'm sure they didn't go that aggressive at all) and COP, etc will do.

I havent seen a 302 stroker hit 400 HP yet.
If you want 400 RWHP on that small of an engine you must use FI or dont bother.

RE: Horsepower TV
What some people aren't getting is it you want a strong bottom end and more power out of your Forced induction system; this would be the route you were going anyway. I mean, why spend the money forging your bottom end when you can spend a little more and stroke it while you were at it?
For me this is just going to be my starting point, and instead of dropping on a high power yielding supercharger I'll just be turning off the street and be done with it. Saleen has the right idea with its new heritage series. Though the 3v N/A Heritage is low compression (For those who want to later supercharge it) so that's not what I want. Since I am staying N/A I need as high and safe as I can go on 93 octane which is probably 10.0-11.0 depending on whatever pistons I go with that give me such results.
