hey, since flash68 requested some pictures here you go.
this new setup cools great; no overheating issues at all. its a huge aluminum radiator. it looks good too!
it used the factory holes; although i did have to redrill the bottom driver side hole (i think maybe because my radiator support is a repro).
i also had to buy a "swivel" radiator neck, because the temparature sensor was in the way of stock water neck. I used a 72' camaro big block hose and it seemed to fit fine!
