Well maybe in 1960 but today as important as displacement is there is no replacement for technology. If I had a dollar for every time I have stomped a big block (even before the blower) I would be a rich man. Technology does a lot to make litte motors do some amazing things, sure with the same give technology and power adder will make more power but I would not expect ford to release a 514 with DOHC, twin turbos and variable valve timing any time soon. There is a lot to do with what makes power on a give engine and its a lot more then just boost and cubic inches.

Well Are we talking production cars? or built cars? cmon dude, 600 ci chevy with tons of n20 can go high 6's in a backhalved car, lets say without nitrous, the motor is still freaking huge, and will beat your turboed 6 cylinder, 302 or whatever, why? because its big!
I went to a track event 'clash of the titans' last year, bb chevy nos against turboed smallblock fords, outlaw and some pro 5.0 cars dan millen, mike murrillo ect... chevy took that event: turbo stang went 7.1.... chevy nova 6.9 at some insane mph, yes both poweradded motors, but all topend isnt what wins races, lowend torque will not hurt you in this sport

That is from a 183 cu in inline six backhalved car.

Technology is just as important as size.

Low end torque doesn't really matter on a racecar when you launch with the revs at peak power and never use the low end. Bigger motors do make more horsepower by virtue of being larger as well, though.

I've been trying to avoid this argument, but felt it's time to chime in.

1.) HP is always a function of torque at a given RPM. HP=RPM/5250 X torque.
2.) Low end torque is an advantagage with relatively high gear ratios and heavy weight. Note: both Supras and Mustangs are heavy, 3000 lbs. +.
3.) HP/TQ curves are easily compensated for with correct gear ratios (rear axle and tranny).
4.)The car with the better Hp/weight ratio, and with good gearing and good driviing, and good traction will ALWAYS PREVAIL.
