I'm building a FED for bracket racing and I'm getting ready to buy a torque converter for the Powerglide. I expect the car to be about 1650# with driver, HP of the carbureted 305 Chevy I expect to be about 250-270, rearend gear I have is a 3.23 and I plan to run 1/8 mi tracks. Also, I plan to foot-brake the car rather than running a trans brake.
I had been thinking about a 9 to 10" converter that would stall at about 2400-2800 RPM up to this point. Yesterday I called a company nearby, BuiltRite Converters, who suggested a 8" converter that he typically would consider a 5000 stall but with my low HP he thought it would stall at about 3000. He's used to building converters for some big HP engines. The price of what I had been looking at is ~$400 for an off-the-shelf converter would go up to about $850 for the 8" unit from BuiltRite.
I think what he's telling me makes sense, that I need higher stall to come off the line, but I know that my little 305 is going to be running out of steam at 5500-ish RPM. The Elgin cam I'm running had a useable RPM range of 2200-5200 if my memory serves correctly. I'm completely new to this and can certainly spend money to do the right thing, but I only want to spend it one time.
Input and advice appreciated. If I'm missing info needed to make suggestions, please let me know.
Thanks
Lynn
