If a V8 engine uses a 180 degree (angle between crankpins) and 4 crankpins, the primary forces are balanced, the secondary forces are unbalanced and the rocking couples are balanced. Imagine this as two, I-4 engines that share the same crankpins. I'm pretty sure this does not need counterweights.
I haven't studied the HISPANO-SUIZA engine, but I'll try to get some engineering texts on it.
