Edelbrock 4bbl TTB

I recently spoke to an Edelbrock tech engineer about their cable operated 4 bbl ttb pn#3878. It's rated at a 1000cfm and fits on the standard Holley bolt pattern. It has a GM Delphi IAC system and TPS and I was told that it should work with the stock pcm. The IAC orifice might be different than stock, so the IAC tables might need some work. Has anyone tried this setup yet and if so how driveable was it? I realize this will probably need a hood scoop to work on a car, but it looks like a nice setup for a truck or engine swap.

Thanks in advance for any input on this.

I went with an accufab. needed very little idle tuning over the fast 90/90 combo.

It works!!!!!

Well, the Edelbrock ttb IAC and TPS plugs right into the factory harness. The TPS seems to give correct position feedback. I could't start the truck as it still had the stock plastic one on. I could't test the IAC system, but I'm pretty certain it'll work fine. This will make an excellent alternative to the single butterfly ttb's since it bolts right up to the Vic. Jr. intake. Now we just need to work out a cold air intake system.
