All 200-4R transmissions have a 27 input shaft spline count. 1982, 1983 and some 1984 700R4 transmissions have a 27 spline count. Late 1984 and newer 700R4 / 4L60 and 4L60E transmissions have a 30 spline count. We must have the input shaft spline count when ordering a converter for a 200-4R, 700R4, 4L60 or 4L60E transmission. These converters will only fit motors with full size bell housings. We also need to know if you have a LS1 type motor and bell housing bolt pattern.
Stall speeds aren't an exact science. All stall speeds are an estimate. Your converter could stall differently depending on your motor. Stall speeds can't be checked at a stop unless your brakes have enough holding power to hold the rear tires from turning. On full size torque converters stall speed listings are based on motors having 230 foot pounds of torque at 2500 RPM. More torque at 2500 RPM will give a higher stall speed, less torque at 2500 RPM will give a lower stall speed than rated.
Guidelines:
1. Converter stall speeds above 2800 RPM aren't recommended for street use. Excessive
RPM for take-off can cause over-heating to occur in normal driving conditions.
External transmission coolers are highly recommended with over a 2000 RPM
stall speed or towing. This is in addition to the cooler in your
radiator. 2. For acceptable performance, axle ratios should be 3:42 to 1
or greater. Ratios in the high "2's" and low "3's" do
not perform as desired with converters with stall speeds above 2000 RPM. 3.
Stall speeds of 3000 RPM or greater aren't recommended for use with engines with
an "advertised" cam duration of less than 292. 4. Vehicles
equipped with transmission brakes, nitrous, turbo-chargers, or blowers require a
torque converter equipped with special features.
Stall speed is measured at wide open throttle. Anything less than WOT will have a lower stall speed. Our 700R4 torque converters lock-up in overdrive automatically. For street use in a 2WD (under 450 horse power) you would need somewhere between 1800 to 2300 stall depending on what feel you like. A 4WD for street use usually uses 1600 to 2000 RPM. Higher stalls than these are usually used on higher horse power motors and for drag racing. The ratings you see on torque converters are for small block motors. The same converter behind a big block will stall as much as 700 RPM higher. A 2800 or higher stall speed on the street would have a jack rabbit take off at full throttle, but have a mushy feeling at less than full throttle. The higher the stall speed the softer the shift feel.
