High vs low RPM

Thats Big Block?


Thats Big Block also? Going far longer between rebuilds, saying the engine will last a lot longer (more durable/reliable)?

While SB = lighter/better weight distribution? This can be overcome via other means if the choice is BB though cant it?

What I was trying to say is that you can certainly build a SB to generate tons of low end torque, but you'll make sacrifices. How exactly do you generate torque low? Think about it. Really it's like I said, this discussion isn't really about high vs low rpm. It's about more than that. Take for example the engine in a Honda S2000. Great little engine that makes good power. But down low it's not a rocket. You need to KEEP the motor revving high to make power. Now, if you could generate a flatter tq curve it would be a different story.

But yes, I stand by my point that a flatter and higher tq curve motor that doesn't need to spin as hard and has more meat (like for example a long stroke BBC, a poncho SB) may be a more "driveable" and "reliable" choice for a mainly street car. For a pure race car it's way different.
