You need a stall converter to run this. You could turn the idle all the way up, but you would really jerk going into gear. You will also notice poor performance down low. I bought a 77 Chevy 4x4 that had a stock flat top 350 with a 280 Magnum Comp Cams camshaft. I would have to put it in neutral at a stop sign, then as I was taking off, I would put it back in drive, and it would jerk pretty severely. I replaced it with a Crane Fireball II cam and it idled very smooth, and had very good low end, and you could leave it in drive. I am not saying switch cams, just adding at least a 2000-2500 rpm stall converter, should take care of your problem of stalling in gear.
