I like RPM.Brutal off the line Torque of a big  engine usually over powers the tires and starts breaking things.I have ran mid 11's many times with ported iron 305 heads on top of flat top 350's with cast crank and cast pistons.I have put the hurt on many BBC 454's. No, mid 11's is not super quick today but 91 octane and not a huge tire and no power adders and nothing breaks .. that is peace of mind.I would bet they made 440 HP or around that at the crank.The above 427 I got all the parts for will easily make 570 HP. That would be plenty to keep a grin on your face and tire rubber on the fenders.I do not have really heavy vehicles  so the 454 or  496 and  larger to me are not needed.Now if you weigh 4000+ lbs  the added low end torque of larger cube BBC would help the launch out.I was researching blocks last week and thinking of a 4.5" bore or larger and 3.76" stroke. 8000rpm 500" BBC.I have friends with 850HP  540" BBC's and Nitrous on top of that and they run 8's in the 1/4. Without leaning on it too hard.I do not need to go there.I wonder what that super gas chevelle with 396" would do with 300HP of NOS stuffed into it.Of course the rules back in the 1970 era allowed those cars to be very light.I like a light car  it is easier on the drive train.</blockquote>
