Im throwing this into my work truck just for basic use non hot rodding, Old motor is out, have another now. The person I got used engine from gave me the holley 600 or 750 not sure which with it, but I know thats one for high performance versus daily normal driving. Couldnt I just go back with my old quadrajet 4 barrel, and buy an adapter to make it fit on the edlebrock intake?? Intake is a 2701 performer esp. Im not too familiar with holleys.

In the pics I just have the carbs laying on top of manifold, even with holley there was a vacuum port at back of intake that would get in the way, unless space adapter raises carb high enough, ill get a pic of it....sorry
.
I was trying to add my next question under images but having a problem, these headers, are they just shorty headers? i have to order new gaskets but wasnt sure what kind they were, also on the new ( red pulleys fan in bottom pic), the bracket for alt and power steering are wider than my original setup, as I have plenty of space under hood, would it matter to change it to original, alt is mounted straight to block with small bracket, power steering kinda of the same.....
