on another note...whats the opinions on that cross over in the intake was to eliminate the H-pipes in the exhst sytem that cars came with back in the day

old timer mechanic said that mopar killed 2 birds with one stone

adds heat for fast warm up and fuel atomazation and does the same thing the H-pipe did to = out/help scavage the back pressure/exhast pulse on #3 and #6 cyls or #4 and #5 cyls

I know I can hear a differance in the glass packs tone/sound with it open or blocked idling at 850 rpms..closed has more deep tone and poping

I think he is but then again what do I know





I don't know about that because the 440 4bbl and 6pk cars in 70/71 had H pipes and the crossover in the intake .
