Anyone running an airbox/adapter box that goes on top of the carb? If so where would I get one. Pacific customs/Moore parts has on for the solex but on moore's site says it wont work on the 11's cause of a clearance issue. Any benefit to run one anyways? Or just leave the hose directly hooked up.
It depends on a couple of things, Yes, clearance is a issue, the class 11 air box has a slope built in to clear the deck lid. Another thing, the engine-trans mount can have a effect on weather it will clear or not. My new car has the motor-trans lowered, gives all kinds of room up top. So does my 67, the 77 I just built has a very large engine compartment which gives enough room to almost not need the slope on the air box. The Air box does give a performance gain, it has a built in Plenum that helps with performance, as does the larger 3-4 inch hose gives way better air flow.. If you go with the airbox, you will need elbows and 3\" aluminum tube and a aircleaner with the 3\" hose= money if you do not have any of it, I would not do it any other way Good luck
We have the UMP, purchased direct from the manufacture, Unique Metal Products there in So. Cal for $115.00. not that much more that a China made EMPI square version. It seemed to give a little better performance than the 90 deg. elbow and three inch tubing we were using.
For a cheaper intake hose go to NAPA and ask to the Speed by Spectra catalog, mostly stuff for imports but they make a flexible intake hose that clicks into place. Very easy to route and about $30.00 Comes in colors to match as well!
