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?
Please clarify which transmission your are actually dealing with, asking about. The 42RH in the title is not the same as an A518 in your question.Those of you who've swapped a 518 42RH behind a small block, who's torque converter did you go with?

Ok, here's the information I have:Transman, do all converters need to be balanced to each engine anytime you put in a different converter? I am changing a trans behind a 318 and a 340. What about the flex plate?
Plum, so it depends how the engine is balanced? You internally balanced the engine so the convertor can be "neutral balance". Is that correct?
I am running a 71 318 with stock crank and rods, new balancer for a 318. Build will be like the Hot Rod mag. "Junkyard Jewel" but with retro roller cam and aluminum heads.
My friend is running a 73 340, external balanced with original harmonic balancer and I believe a B & M flex plate. He said it has a neutral balanced converter so his flex plate must be externally balanced to his combo then (he didn't build it, just recently bought the car).
The reason I am asking is because we are both going to do the 8hp70 behind our small blocks and I making sure we have all the info we need. I thank you guys for supplying that info.
Some other stuff I need to know: stock 8hp70 flex plate and torque converter - are they neutral balanced or external balanced? Can I tell by looking at them? I have one on the way to me now, be a little while before I get it to look at the parts.
It is, we were talking about the 42RH but I am using the info towards the other project too.
