'97 aint TBI (not stock anyway)
My 406 w/ vortec heads, comp XE268 cam, 9.2:1, with 454 TBI and 17-18# fuel pressure (needed additional inline pump) ran great. Performer RPM intake and adapter plate-ran fine. On the edge of needing higher stall converter than the GM police car converter (couple hundred rpm over stock). Custom chip with EGR turned off. Very torquey thru middle rpms-great hi-po pickup engine. Very mild lope @ idle.
'93 1500 truck.
