Lemans 350 V8

Hi everyone, I have a 69 lemans 350 motor that I just got my hands on. The problem is the guy before me had taken off the intake, water pump, and who knows what else. The block and rest seems to be untouched. I'm not familiar with pontiac motors other then they have great potential for higher torque. Can someone tell me what I need/don't need and how to put back together the intake on top of the motor? What everything connects to, where, etc? Thank you very much!

    I have a '76 Grand LeMans with a 350-4bbl, the "P" code California/high-altitude smogger special. Dunno how similar it would be. I could try taking a pic of the engine bay, if that would help.

    It doesn't have a stock intake, though. A few years back my mechanic put on an aluminum Edelbrock intake, and one of those Mopar style ignition systems where the coil is mounted on the firewall, rather than housed in the distributor.

    I also have a '67 Catalina with a 400. It was originally a 2-bbl, but at some point in its life, before I bought it, it was upgraded to a 4-bbl. Dunno if a pic of that would help as well, as the 326/350 and 389/400, and even 421/428/455 were all pretty similar. My understanding is that Pontiac never made a true "big block" and "small block", like Chevy, Buick, Olds, Ford, and Mopar did. But rather, it was more of a "medium block" that started as a 287.1 in 1955, but ultimately spanned a bunch of displacements on up to the 455. They had raised decks for the 421/428/455, compared to the 389/400. Dunno if they modified much to come out with the 326/350.

    If you want, I can try taking some pics of the engine bay on that one, as well.

    A Haynes manual for that model might have the info you need:
