One other thing to consider, last time I checked, the JW ultra bell to bolt a 518 to a BB was around $250 cheaper than that wilcap adapter, not to mention probably having to buy a special aftermarket flex plate to run the chevy torq converter. I know they also make an ultra bell to mate a BB to a chevy th350/400 trans but not sure if that would also work on a 200-4r or 700r4
No, the flexplate comes with the wilcap, so nothing special.
