Questions from a Newby!

[kf4jfk]

First off I want to say I have fell in love with this forum. There is so much valuable information that I find myself losing sleep, but i'm not complaining. I have been searching for my next toy for some time and I finally found it. Its a 1964 GMC Fleetside Longbed w/ 305ci V6 and a 4-speed.

Let me add that I have tried searching this forum and other sites on the web for the answers to the following questions, but with no success.

Now the questions:

1)I know that these engines are rare and only were in the GMC trucks, but I cannot find any specifications on the engine. I am needing to know what weight oil and capacity. Any recommendations Accepted! I have checked the "6066 GMC Guy" website, but have had no luck. The reason I need the capacity is the oil pan has been knocked in from the previous owner. It does not leak and i do have good oil pressure on the gauge in the cab. Can anyone help?

2)I am loving this 305 V6 engine. What a power house! It has a Rochester 2 barrel carb on it. Is this original? (I had to pull it off and clean it due to the truck sitting for some time before I bought the truck.) The only reason that I am questioning the originality is I cannot slow the idle speed down. I have backed the idle screw all the way out and it still idles at 1300-1500 rpm. I have checked the pedal linkage and seems to not be in a bind. Other than the idle speed, the truck has a pretty decent powerband.

I appreciate any all help. I am truly stumped with these issues. I also want to apologize if I put this thread in the wrong place. I am new to the forum life, but am looking forward to busting some knuckle on my new bucket!

Thanks so much in advance for everyone's help.
