Thanks for the suggestions.

Re: Intakes, I just revisited one of Jim Hand's old articles. I'm sure you guts have all read it but In summary comparison to stock cast iron::

* Pontiac Aluminum HO Lost .08 sec. and ,4 MPH
* Edelbrock Performer No change in ET or MPH
* Edelbrock Performer RPM Lost .05 sec. and .5 MPH
* Edelbrock Torquer II Lost .0l sec. and .1 MPH
* Edelbrock Torquer Lost .29 sec. and 2.85 MPH
* Holley Street Dominator Lost .25 sec. and 1.9 MPH

As my motor closely resembles the specs of his original build as tested (sans porting and 1.65 ration rockers), my head says stick with the current dual plane and swap my Jet Stage2 800CFM Quadrajet on it and see what happens. My gut says I will be putting the Torker II and Quickfuel combo on before it's all over though.
