the classic 400 BB ( 454 pre stoke. ) are` like RLG said, torqe not rpm
9K is a death sentance on that car
7 K is out of powerband i belive, as far as i know if hes useing an older 400 block, or even a newer one, the powerbands are way low.
will my trans am motor pull 5K yes, will it pull 7 K yes.
do i ever have it past 4K no
thats why my TA has like 2.56 in the rear or something like that.
classic BBs dig low RPM and they produce Monster Tq.
for 9 k rpm id start with a small block or a good tuned LS1 atleast then build it up
im not sure about the manifold, mines still stock.
