Fabricated intake IAC

Post by dstaley »

Hey guys,
I'm doing my homework on a new EFI system for a 409 SBC with a port injected tunnel ram base and a fabricated plenum. The inlet doesn't have any apparent provisions for IAC so I'm going to need to add something, either with hoses or a little machining.

Here are some pictures of the intake assembly I'm starting with:

I have no idea where to go from here as far as finding something to retrofit- either something connected with hoses or some kind of basic machined manifold for the air to bypass the butterfly.

Suggestions?

We've got a remote mount block to fit a Jeep / Delphi IAC valve with hose fittings if you want a stepper IAC. For PWM IAC valves, may BMW and VW valves have hose fittings and could be used there.
