318 in the tens

Nope..BY the math, it takes 450-470hp at the crank to accelerate 3000lbs (a guess on my part) to a speed of 120 mph in the 1/4. (estimated mph. with gearing, a lower powered car can run slower mph, but get to the end quicker) How you make hp is not the issue. It takes that much. The airflow needed to make that hp number is very roughly 235cfm. Running a 340/360 port that's not a problem (taking out the emotion of spending what it costs...lol). Running the smaller 318 port, that could very easy be a problem. As I've said..Not impossible I dont think, but highly improbable. I have been surprised by much smaller making more N/A...But they make it by rpm. an 10K rpm Nissan a friend owns is one. Dynoed at 295hp to the tires. 2.4L with J spec head, no boost. No bottle. If that were a 318 size (5.2L) it would be producing (conservatively) just over 700hp. The secret is the heads and chamber, combined with rpm. 4 valve heads that flow just shy of 200cfm and as close to "perfect" chamber/piston design, and have it make "x" amount of power per each firing stroke, and make as many firing strokes as possible in a short period of time. (Rotations Per Minute)
Thats a far cry from 140cfm, poor quench, poor chamber, large bore (comparatively), and lack or rpm tho.
