    i heard that gm has come out with a 90mm electronic throttle body with a sick intake manifold, along with 38# injectors and fuel rails and even heads. The heads flow 300cfm. I was told the heads were about 375 and you had to by the other which is about 500.

    Must be thinking of the L92 heads which require 2 at &#036;375+ each, &#036;500 intake which is complete with fuel rails, injectors and throttle body(electronic), 8 intake rockers and 8 exhaust rockers(about &#036;25 each x 16), not all the same, rocker bases and new pushrods(&#036;180?). I don&#39;t know about valve covers but the entire package is going to be sweet when it becomes available as a kit&#33;

    Damn it Yankee just set aside 6 hrs next weekend and port that TB yourself&#33; It&#39;s easy and basically free and the results are noticeable. I put u/d pulleys on my v6 and couldn&#39;t tell much difference and I doubt youd feel much with a cut out either. You will definitely notice the difference with the ported TB. I have seen proven 7-11 hp gains from this mod.

    I&#39;m not a bit interested in doing it. I&#39;d rather just pay the cash and get one from someone who has done them before rather than spend the time and possibly mess it up. It&#39;s only &#036;150. That&#39;s worth my time, to me anyway.

    Thanks for the numbers though. Hey, if I get 7-11 hp, that&#39;s 7-11 hp (cheaper than an intake for about the same gains).

    Thanks Moto.
