Jack21, I've used several of the Holley systems with the latest being the digital. The old systems were a bear to tune and they never covered the rpm range well. The new system worked well on the dyno after we created a new fuel map. The ones they supply are very generic and need major mods. I spent many hours on the dyno tuning with a laptop. The engine went to Miami Cobra and I know he had to tune it further for the street. As far as I know it is working well. I have used the OEM ford port injection, the GM throttle body, GM tuned port. All of these systems worked well with the stock engines. I've never tried a modified engine with the OEM injection. I'm still a carburetor man, there's something about the sound of a 4 bbl opening that makes my blood run!

Back to the Holley carbs, We've tried just about all brands of modified Holley carbs from Barry Grant to Pro-systems, to Bowlus, to C&S. They all charge big bucks and the gain is very minimal. We modify all our own Holleys at about half the cost with a better gain. We had one C&S that a customer paid over $1000 for. We took a simple Holley with some minor mods and gained 5hp with a savings of about $500. If you get the Holley Carb book it discusses all the mods necessary that most of the aftermarket companies use. The Edelbrock carbs have 2 metering rods and jets that are held in with one small screw on each side. No gaskets, no pulling the top. a 5 minute change. No power valves to blow. I'm sure there are people that love and hate the Edelbrock. I have just had such good luck with them I'm staying. I'm not against Holley but for the street, reliability and trouble free running mean alot to me. Many of the people I sell to couldn't even find the carburetor let alone fix one.
