Ihave had both mechanical e.f.i. and very happy with current set up. If I knew how to post pictures I would show both systems. Ihave the twm on cobra and hilborn on boat. The only way you would be happy with mechanical on street would be with slow opening throttle linkage, T.W.M. works great on street. T.W.M. mills the manifold to help fit in cobra. They do not get into electronics , I went to B.D.S. T.W.M. looks so good I hate to cover up with air cleaners. I will try to make clear upper and lower with filter between to show off , it looks that good. The throttle bodies can be ordered up to 58mm which is good for us with stroker motors. I went to trouble to drill and tap underside of manifold to hide lines, used stainless steel hardlines. Engine going to sacramento to be rebuilt with new stroker crank ,cam ,tune up on dyno.
