    I know im probably getting annoying with all my posts but, i need some more insight. Im putting this intake on my Blazer but there are some holes that i dont know what they are used for. Of course the back is for the distributor, middle for the carb, and front for t-stat housing. But there is on inbetween the carb and distributor. Like Picture below.The bigger hole closer to the carb.

    That is for a "T" fitting for vac lines. Or for a plug if you dont need the vac lines.

    Here is a better picture. I need info on the hole inbetween the distributor and carb. And the two big holes on each side of the tstat hole.

    The one in back is for vacuum(brake booster, auto tranny, etc.) if your carb doesn't have enough ports, the two in front are coolant..... I put a nipple on one for the heater core inlet (the one on the pass. side) and plug the other.

    yeah the two in the front for coolant. I have a nipple in one, and in my application I have my temp. sensor there. I believe most take a plug though.

    I believe the front fittings are 1/2 NPT (you'll need one plug and one nipple fitting for 5/8 heater hose or 1/2 heater hose depending on the year) and its a 3/8 npt plug for the vacuum port in back

    And BTW whatever machine Edelbrock uses to thread those holes is terrible.... use teflon tape and crank em in or they'll leak like you wouldn't believe

    That manifold should've come with an aluminum block off for the choke. It looks like a square hunk of metal with a couple bolt holes. On mine there was also a small hole in that blank off which needed to be plugged.
