I have 72 chevelle and when I put it in drive or reverse it wants to stall what could be the problem? My idle is at approz 1000, I'm running a Barry Grant carb 850 demon, 496 CC and turbo 400 tranny. Been running this at the track the last two days my best time was 11.77 at 117 miles an hr in the 1/4 mile. My 60 foot still suck at 1.81, I dont have a transbrake. Any help would be great

I would start by checking for vacuum leak. How is the idle?

Have to say thanks to Two Feathers out of Grand Prairie did a knock off job working on my car. Worked on the carb and when i put it in gear it does not stall at all. Maybe drops 50 RPM. Thannks
