Keep in mind one of the important keys to building 283s is to keep the air moving as much as possible at LOW rpm for street use. Anything you add to a 283 to improve breathing at higher rpm is gonna take away from the low end. Getting 283s to move a heavy vehicle around like our trucks & do it in snappy fashion is a balancing act. From experience I can tell you when you put an aluminum intake & that Holley carb on there you're gonna lose some low end. That's why my recipe is a proven one, that stock intake & 4 jet Rochester will really surprise you! (Just aint gonna look as sexy!) Of course a set of double humps & the 151 L79 327 cam will get you another 800-900 rpm easy you sure will miss the low end you lost!
Building the 283 aint xactly like sticking an intake & cam in a 350.
But you're gonna have a lot of fun doing this & really enjoy driving a crisp running 283!
Can't wait to watch your build thread! Have fun!
