i have alot of aluminum laying around and am going to build a sheet metal intake for 2-4500 series throttle bodies with injector and nitrous bungs, anybody ever tried this before? I have a miller synchrowave 250 dx ig rig that has been sitting to long so i better fire it up and see what i can do, i am also going to polish it and have it chromed because a fabricated manifold with those beautifull welds polished and chromed looks soooo good along with the 2 billet polished full throttle throttle bodies on will look killer, but if it doesn't work all i will be out is about $20 in scrap metal and some fun trying right? been doing alot of research on them but any info would be awesome, tube sizes , taper, angle from top of engine plane to top of intake plane, plenum volume.........
