Stalling when going into gear...
I recently rebuilt the motor, 250 duration on the cam big lift, vic jr. intake, 11 and a quater compression. It idles at like 1200 then I go to put it in gear and it drops to like 500 or 600 then stalls or just stalls out. I'm thinking it could be the torque converter because I have the original plus I have trick 195 cnc machine heads.

That's a huge cam if you're talking duration @ .050
If that's right, you need a new chip. My car did the same thing when I put in a 224@.050 cam. A new chip made my car idle without dying constantly. PM ski_dwn_it(Jesse) He'll hook you up

You need to be more clear. By
did you mean you don't care about advertised duration? If so, and those numbers are @.050 then the cam makes more sense. If that IS the case, you DEFINATELY need a new chip

Oops, I guess i was selective reading. I don't know if a higher stall converter would cure that. I noticed no change in mine when I went up to a 2500 stall. Is the carb tuned?

That is an awfully large cam for a ~350 engine. Besides helping the idle, you need a MUCH higher stall converter. That cam isn't going to make diddle squat for low end torque. The idle can probably be tamed, somewhat, by dialing in a short advance curve and massaging the carb. It COULD be given better manners with a well sorted out EFI system.

The carburetor still needs to be adjusted a little better. I have the had the vacuum gauge on it and everything seems to be fine. I just think I need a 3500 stall. I just wanted to rule out any other problems as in hei or bad fuel pressure etc. Thats what the guys at Summit tech said. I was just hoping I wouldn't have to go with that big of a stall because I'm going to have to go with fan setup tranny cooler.
