Friends Are telling me To get Rid of MY 3000 Stall.. its only For Racing. ill get my Low end Torq From a stock Stall conv. and If so what should i get That is Lumpy to go with a stock Stall?

"lumpy" won't work with a stock stall converter. Your friends are full of horsefeathers. Keep your 3,000 stall converter and make sure you add a nice, big transmission cooler in the front that will get a good dose of cool air.

yor engine will start making torque where your cam powerband starts,thats where you whant your stall speed to be. on my 383 the cam card states that the cam will make power between 4500 -7800 so i installed a 5000 stall - sounds awsome when i hit the trans brake and nail it!!!!

yep

. . . and if it's a 700/R4 or 200/R4, you better have a lockup converter, unless you like southern-fried transmission.

hey all im a bit new to this
can anyone tell me exactly what a stall converter is?
my guess is that its a torque converter that engages at a certain engine RPM like 3000 or whatever its listed at. id appreciate any replies, thnx

honda, you are correct in your assumption, but let's get the terminology right. Everyone says "stall converter". That's like saying "horsepower motor". You have to give it a value for it to mean anything, like high-stall converter or low-stall converter or 3,000 stall converter or 2,200 stall converter.

When cars are delivered from the factory, the converter is matched to the motor to please 99.9% of the buying public. Grandma doesn't want the motor revving past its normal operating range when she's heading out to Bingo and making excessive engine noise. She also won't tolerate the dismal fuel mileage that comes with a looser converter, so the factory installs a converter that will do the job for the majority of the public.

The problem arises when Henry Hot Rod decides to change the cam in his motor to get more horsepower. Any aftermarket cam that he installs will move the powerband up in the rpm range and no longer makes power down low where Grandma likes it. The new wilder grind cam also does not want to idle like a stocker and requires more rpm to idle. Now, with a higher idle, the motor is stalling up against the stock (for instance 1,200 rpm stall) converter, so holding the car at a standstill requires both feet on the brake. So Henry opts for a converter with a higher stall so he can sit at stoplights with the motor idling higher and the car will not want to creep. Also, with the motor making power at a higher rpm, Henry can get into the power band of the motor quicker with a looser converter.
