A sane observation, but since exhaust and intake are on the same side, it appears Tracy’s plywood box IS over the exhaust.  I assume he used heat shields to deal with that?

Something to remember an airbox like that must be on the "cold side" of the engine. Don't put it over the exhaust.

Hahaha... I always heard of Tracy's simple intake manifold but never had seen the actual setup (except for zoomed out shots in Contact mag).  Now I feel better as I move forward with my build :)  Thanks for sharing Charlie!!!

Hope Tracy doesn't mind; here's a shot of the Renesis manifold. I believe that the tubes inside the 'box' were later extended to be near the opposite wall. IIRC, Tracy said that the tubes are ~11" from the face of the block to the end of the bellmouth.
