i am in process of putting a 455 in my 73 century. i have a turbo 350 in car that works great. my question is what benifits does a stall converter have. this is a street car. maybe raced once a year.motor is a 70 455 decked to to get me to 10.1 compression ta 212 cam 750 holley single pump.stock rockers,stock heads, fuel pump,oil pump.oh and edelbrock performer intake.stock manifolds with 2 1/4 inch exhaust with flowmaster mufflers.any replies appreciated.also what kinds of converters and what stall would i use if i would go with one. thanks Ray ________ Kitchen Measures
A higher stall converter lets the car leave the line at a higher RPM. The engine makes more torque at that higher RPM, and provided you have the traction, provides better standing start acceleration. A higher stall converter is especially useful in an engine with a hot cam. A performance cam holds the valves open longer, which bumps the power range of the motor up from stock. If the power range of the cam is 2500-6000, and the converter stalls at 1400, well, you see the problem. In your case, you have a mild cam, power range 1500-5500. The stock converter should be fine. Also, be aware that a converter will stall higher behind a big block, because of the higher torque production. So, if you ae using a converter that originally went behind a small block, it will almost certainly stall higher behind the big block.
