Please clear this up for me
What the heck is a stall converter?? Does it have something to do with torque converters? Because I have a manual tranny so I thought that I wouldn't have to worry about it, but a lot of things say something about choosing the right stall converter speed. Like buying camshafts and things like that. So do I have to worry about it when things talk about stall converters or since I have a manual I can just look past it???

Re: Please clear this up for me
Stalls are only for automatics.You are good to go as far as cam choices.

Re: Please clear this up for me
us automatic trans guy's can only run so big of a cam or we wind up with no vacuum to run power brakes..
the bigger the cam ... the more stall speed you need in your automatic transmission converter.. the stall speed is built into the converter... the bigger the cam the less vacuum your engine makes... you need vacuum to run power brakes..and vacuum to run a/c flapper doors, heater flapper doors and such.. |

Re: Please clear this up for me
I'm not familiar with the term "stall converter". Auto trannys use a "torque converter" which acts as a fluid clutch, allowing the motor to continue running, even when the vehicle is stopped.
IIFC...TC's have different "stall speeds". This is the RPM at which the motor begins to overcome the fluid action of the TC, thereby applying torque to the tranny. Stock TC's begin this roughly around 1500 RPM, allowing smooth, uneventful acceleration from a dead stop. Hi-Po, or "loose" converters, will move these RPM upwards, say to 2500-3000 RPM. This puts the motor in a more ideal power range for stronger, harder acceleration. The effect can seem like a slipping tranny, but is normal operation. So...as previously stated by my fellow members above...since you have a manual tranny, "stall" or "converters" is not something you need to worry with.
