Bob, I have a cable throttle linkage and the E'brock hooked right up with minor adjustment. The plumbing was easy - inlet options on either side. I installed a new inlet log with a pressure gauge port and of course a new filter. I used the same adjustable pressure regulator I had with the Holleys.
They say the louvers also vent underhood pressure and keep the front end down at speeds around 160mph, but I'll have to take their word for it! The fastest I've managed down here is close to 140. I've taken it over 130mph three times now - very early in the morning while eeeeasing around potholes and watching out for goats, horses and a family of pigs that frequents the area. Huge adrenaline rush but I don't think I'll be doing it again.
As far as fuel delivery under hard cornering goes, one thing we have in abundance here is corners. We just completed a new National Tennis Center near a sports stadium not far from where I live and there is a nice section of new, flat, unused road that winds through the undeveloped area. I also installed a new
oil pan and I've run it hard around the little "test circuit" to see how the
oil pressure holds up. The pressure is fine and so far the carb works flawlessly in the turns.
I realize there's a lot of brand loyalty with Holleys, but the way I see it is these companies care about their bottom lines and as long as I pay my money, I don't owe them anything else. Plus, they have legal teams to defend their names, so they don't need me for that.
I'll use what works for me and if the Edelbrock develops problems or turns out to be a disappointment, I will report back.
