Torque Converter and Flexplate Kit

    Why does the kit specify small or big block application but if you follow the link for the torque converter included - it says “recommended for small block only” in the description?  I’ll be using this on a gen 4 427 BBC with a TH400 & 4.11 gears. 

    Asked by: Abel Garcia
    The stall range can be different for big block engines. the converters will work they will normally stal at a higher rpm because of the torque increase.

    Is this the best converter (kit) for a 1967 Camaro RS 3:08 Non-posi rear with a BluePrint 3550CT/CTC Engine. Recommended from engine manufacturer is 1800-2200 stall. Would I be better off with something lower than the 2000-2300?

    Asked by: Stainless
    This kit will work well with the Blueprint engine.
