An engine like that will probably benefit from a spacer underneath the manifold top to increase plenum volume.

X2 I made a delrin spacer for the Gutsram I tried and it picked up .09 in the 1/4 in back to back test over no spacer and just the flat top. Still did not run as fast as the original TR, but I am running a baby engine.
What I have found with both intakes on my engine is they both like shear plates.

We had a hand-me-down sheetmetal tunnel ram on the Grocery Getter and it was notorious for stalling at the end of a big burnout. It had a pretty big plenum.

We switched to the Gutsram and problem solved.

So I guess my general thought is to use spacers or something like that (not permanent) so you can try different plenum volumes till it's optimized.

FWIW,
Eric
