of course, you could always go for the biggest normally aspirated 4.9L ever! hehehe... if you shave the heads .050, and use Northstar pistons ( use the stock sleeves, just have them bored .040 ), you'll get in the neghborhood somewhere of 11.5 to 12:1 compression.. of course, pump gas is useless at this compression unless you use a different ECM entirely, one with a knock sensor of course..have a custom built valvetrain, and a very high lift cam... |
