Shafts-Stacks-Butterflies- Stops- Fuel Rails- Bored for injectors- with Vacuum system mounted and TPS Switch mounted
You furnish the rest ,
The 348-409 engines were the beginning of true high performance engines for Chevrolet. At its' peak, the 409 made the magical one horsepower per cubic inch, and was not only very popular with racers, it was feared by the competition.
Now the 409 is back and it’s as hot as ever, especially when equipped with a Hilborn. A Hilborn injector from Alkydigger will breath new life into your 409, whether running stock or aftermarket aluminum heads, producing awesome torque and power along with race inspired engine acceleration. But if drivability is your direction, then we have you covered on that too. Our injector manifolds have smooth low end power, calming even the largest of camshafts. See for yourself why some of the fastest racers and the savviest of street rodders prefer a Hilborn Injector or EFI kit.
Why is a Hilborn better?
Since a Hilborn Injector is part of the IR (individual runner) family it does not suffer from the disruptive cylinder to cylinder pulses associated with a common plenum intake. These pulses promote fuel separation from the air carrier, the slowing of air movement in the manifold, and the inability to realize engine potential due to poor burn characteristics in the combustion chamber. The IR design of the Hilborn isolates these pulses allowing the engine to make more bottom end torque, have increased throttle response and most importantly allow the engine to accelerate faster. Most applications will also see a significant increase in top end power. These same attributes also allow smoother low speed drivability.
Besides, nothing looks better than eight stacks sitting on top of your engine. Have the best of both worlds with a Hilborn!
