I've been running an Edelbrock on a ZZ4 GMPP motor for about a year, gas milage is good, very reliable and it works great cruising around town. I've spent alot of time tuning with different jets, rods and springs but just can't get a performance I want, lacks topend power (it's a 600 cfm, maybe not enough). Thought about the 750 or the 650 AVS Edelbrocks for a while, but I just bought a Speed Demon this week (on Ebay, comes with fuel line for $415). A friend of mine switched to the 750 Demon a few months back for his 383 GMPP, says it works great, very noticeable performance increase, although it runs a little rich.
I'll let you know how it works, should have it on in about a week.
