TODAY is a Great Day to visit our Store and order the parts you need for your truck ! ! !
Rebuild your Quadrajet, or get a replacement Q-jet if it's a job you don't want to handle. As far as an intake manifold if you aren't concerned with massive power gains and just want an aluminum dual plane intake I think I have one I could sell at a bargain price. Otherwise here's an economy choice that I've actually used http://cgi.ebay.com/ebaymotors/SBC-CHEVY-Dual-Plane-Aluminum-Intake-327-350-383-400_W0QQcmdZViewItemQQcategoryZ107063QQihZ012QQitemZ220099930162QQrdZ1QQsspagenameZWDVW

Doesn't matter - they're all calibrated the same for replacement. OE they sometimes used different needle assembly and eventually all used a rollover check ball for the bowl vent. All reman'd come like that now anyway. Basically it should be bolt on. Do you have electric choke? Make sure you get an electric choke carb.
