cool vid and very good for only 9.5 psi on a big t66. My concern is though you may consider building your bottom end, cuz an NA block should have higher compression and weaker parts than a GTE block, which isn't capable of reliable 600hp loads. Ya spent all that dough on that t66 get a FMIC FFIM and a built bottom end and ported head that thing would be freaking nuts then, good car and vid though
