350 with 454 TBI

I upgraded to a 454 TBI upgrade quite awhile ago. I thought I'd share the pictures of the upgrade. I have a 93 GMC pickup. I decided to use a 93 454 TBI with Police 350 injectors (17084327). The 93 454 TBI uses the same new style TPS like the 93 350 TBI. The adapter plate is available from SPR Performance. I bored the TBI intake for larger throttle body bores (52mm), and had a "Go Fast" machine shop radius the throttle bores. Total cost ... less than a new Edelbrock TBI intake from a "Go Fast" parts store.
