Does anyone make an aluminum dual plane intake manifold for using EFI? I know edelbrock has the LS1 carb style dual plane but only open plenum injection models.

^ Just want a regular DP intake that you can stick a TBI on top of?? Should be a typical 4bbl DP intake. Depends on what TBI you're using.

You're not looking to run the typical injectors and rails, I take it? Something like the FAST EZEFI setup?

Here's a list... See if it works for ya.

Holley has one for 4150 Accufab or Fast type TB's and 4150 style carbs. It's a Mid plane dual 4150 set up though so you'd need two of whatever you chose.

I meant something using rails and injectors. Sorry about the confusion. Just curious as I've never seen them...only the vic jr. series which are all open plenum designs.

^ Yeah. I think you're limited to the Vic then.. AFAIK.

You've never seen them because there is no reason to make them for port-injected engines. The dual plane is designed specifically for carb'ed or throttle-bodied engines with the air & fuel mixed.

^ Hmmmm.. Interesting.. Learn something new every day. OP could do a DP with a TBI setup, if he wanted tho, right?? I've had my eye on the FAST EZEFI lately. I'd LOVE to have a 90's Silvy to mode with that.

Yup, dual planes should have a low-end benefit for throttle bodies.
