It comes from Holley with an intake. I buy the kit complete without electronics. The intake is essentially a Dart single plane. It looks very, very similar
The kit comes with the intake, fuel rails, injectors, crossover tubes, throttle body, IAC, intake air temp sensor, TPS, MAP sensor, and a coolant temp sensor. The only other things needed are the electronics......ecm and harness. For that, I use a Mefi 4 (or whatever existing ecm a customer has) and a custom harness. The complete setup (minus the ecm and harness) is around $2600. And it is worth EVERY penny.
I had built a 555 ci engine a while back. The customer really wanted the 500 efi intake. It was a really healthy engine(aluminum heads, almost 10:1, etc) that should have made some decent power. I tried and tried to break 600 hp. After an entire day on the dyno, it finally made 604 hp, but it was a piece of crap. The intake had a ton of work done to it.(extrude hone, larger throttle body, etc) I changed the intake on the dyno with the Holley unit and the first pull it made 85 more hp. After some tuning, it made a total of 97 more hp than the 500 intake.
Let me know if you have any more questions. Thanks.
