    I need help fellas!

    I have an 84 k5 with a 350 small block crate motor in it.

    I bought a 454 tbi adapter plate so I can "bolt on" 350 tbi stuff. I really need some guidance on how I mount the sensor brackets and exactly how the throttle cable attaches to the tbi. Has anyone done this? Anyone have pics?

    The stock TBI sensor brackets won't work properly - in the same position, anyway. The TBI intake is a lot different than the carb intake.

    You could always use a TBI intake. The center two bolts on both sides need to be drilled so they match the angle of all the other bolt holes.

    yeah, i've done the "redrill thing" before... I'm trying to get away from doing that. This is supposed to be easier. :D

    Yeah, you can use a large cap HEI if you have a fully computer controlled one. My 86 K5 is a california model so it had a computer controlled everything (Carb, dizzy, etc.). Not sure what years have it, but there are some floating out there.....maybe mid 80's before the TBI came out????
