Adaptor Plate for Big Block TBI

[Dr_Grip]

Hi guys,
I just got my hands on a TBI unit from a 1992 Chevy 454. Which adaptor plate do I need to fit it to my Edelbrock Performer 4bbl manifold?

Sadly, I don't have space under the hood to fit a spacer as well, the air filter barely clears the hood as it is.

(A summit racing link would be perfect).

Any help, as always, is appreciated.

Find one that has the same bolt configuration as your intake and 2" bores so you can get the most out of the BB TBI. I'm looking to do the same thing with my 383, just need to track down an intake.

Go to the Trans Dapt site and search tbi. It will show you what you want and then you can get part number and order from summit. I found the 454 width gets you pretty thin on the edges of the square intake. Too bad you don't have a little more room, then you could use a spread bore/square bore spacer upside down with a spread bore adapter and that flares out giving more room.
