Those of you who've swapped a 518 42RH behind a small block, who's torque converter did you go with? I'm looking for something with a 2500 stall. Are they the same 23 spline torque converter that's used on the 727?
Nope not the same.
A500 42RH 26 splines--like the 904
A518 46RH 24 splines--like the 727
727 Early 19 splines
727 Late 24 splines
Converter will have to be balanced to match your engine. All A500's have no weights, A518 may or may not have weights. High stall should not be an issue, but you will need to contact one of the known high stall builders as speak to them.
