the 781 heads are supposed to be better, heads we used them for racing.
this is what I did after I found a leak in the original hard lines. has worked good so far, this is the hose used in racing . I wanted to use fuel injection clamps but they don't make them this big
bought these seats off ebay, going to install them after my truck comes back from paint . from a Honda accord, forgot to mention this is the almost exact color of my original bench seats now , so it should hold up for awhile only have to do headliner.
