What is a steamroller?

Any cam suitable for a low-compression engine, should send up red flags as to racing. And when the advertised is not disclosed, two more red flags should go up.
Yeah, I know the scoop, from 8/1 to 11/1 is only about 6% absolute power difference. But what is the difference in real numbers, and the power cost from stall to peak? That's where compression shines; in the higher average power to get there. That 6% is about 1 full cam size at the peak; but the compression boosts the power all the way down to idle, while the bigger cam steals low-rpm power to get the additional peak power. If you install a 4000 TC then the low-rpm doesn't matter to you. but 6% is still 6% no matter how you look at it.
IMO, a Whiplash cam is a cheap way to make an engine sound like a monster at idle, yet still have some torque at stall, so you save the cost of installing hi-compression components. This is great for the A&W cruiser.... not so much for racing,lol.
If yur gonna stick with a teener, yur gonna need the whole package, no shortcuts. Choose your MPH window, determine your P/W ratio, build the engine to satisfy that,gear and stall it; go have fun, whittling down your ET.
A bigger engine lets you be sloppy for the teener power window.Most of the time sloppy is cheaper.
