Customer q:

Please recommend a lockup torque converter for street and strip for a conversion from FMX transmission to 4R70W transmission using the original flexplate. Engine is standard with headers, 6AL and Holley 4160. I plan to supercharge the engine next year. Currently, my converter's stalling at 1800 rpm. Can I have higher stall but still have the car creep on idle? Are you confident it’s a strong reliable product? Thanks.

Thank you for giving JEGS the opportunity to assist you with your technical question. You could use a little high stall speed 2400, Performance Automatic #PA45251. Performance Automatic offers a great product that we do not have many returns with. You could also use a FTI converter # SB2400DE.
