    Thinking about helping out my 87 TBI 454, starting first w/air, then working my way into the motor. So here's the question:

    Compared to the funky first-year cobbled together TBI intake w/the funky coolant-heated TBI spacer (what the hell is that for, anyway), is the Edelbrock TBI intake an improvement or not?

    Comparing the two visually it appears the the Edelbrock has a better set of runners on it, taller and straighter shot (slightly) than the factory model. For $250, I hope it helps improve SOMETHING.

    SO: anyone install one? and what happened.

    good 4 barrel intake with adapter plate flows much better than tbi intake. and ditch the heated adaptor. then i would also get ajustuble fuel pressure unit. thay say adding 2-3 lbs over stock setting is good also.
