Dean,

I don't understand the problem: IIRC, when I had the 455 with OEM
manifold, the Holly Throttle Body and later the GM TB, was no taller than
the Quadrajet and so did not require raising the hatch cover.

Even with the taller Cad500 installed with the GM TB, I've only had to
slightly raise about a 1/2" high aluminum dome over the cutaway plywood
hatch cover.

Even when I bought the GMC with a Quadrajet on the 455 with an Edelbrock
Performer manifold, the hatch was raised by only about 4". I have to
wonder what manifold your friend is using that's even taller than that one.
