spacers and performance

[67ragtp]

I got the manifold back from wilsons, they really did a nice job, I had them port the upper part of the plenum as well. So I sit the throttlebody on top and the two cap screws that operate the progressive linkage hit the fuel rail. What are my options, as a mock up I lifted the throttlebody one inch(shown in the pic) and figure I will buy one of wilsons tapered spacers. Is this a bad idea for this set up, will the motor lose throttle response, just not sure how a spacer will affect the flow good or bad. Im also starting to run out of clearance for the cowl hood, that linkage arm sticks up high and as it rotates it hits the bottom of my air filter base. Any suggestions are appreciated- Thanks Rich

I have the same TB, the throttle linkage hits the bottom of the air cleaner even with a 3/4" spacer on top of the throttle valve.

I don't know what they were thinking with that throttle linkage, bit I think I'm going to have to cut mine.

EFI69CAM,

Can you post a pic of your manifold/throttlebody combo, Its very helpful to see how others have set theres up. Did the throttlebody fit between the rails ok.
