Wayne, Gary & Steve:
I'm curious about the 51SI of filtration per side that Wayne mentioned. I'm the non technical guy, but my engine builder fabricated a Lexan box(as in bullet proof glass quality I'm told) with top and bottom panels to see through. We designed it with Lexan front and back panels so I could see out the rearview mirror and through the stacks.
The side areas are the filters measuring about 18" by 2-3". The 383 stroker ran fine on the dyno at long full-song pulls at 6,000 with no leaning out. (peak HP was at 5,800) Does the 342 at 6,500 need more than the 383 @ 6000 or is it possible there is a large safety factor in the filtration calculation for off road racers.
Pictures to follow.
