OBSWIZ quoted me $760 shipped for the 6.0 converter and that included the $150 core charge. he said its good for 500+ hp which is way more than my truck will ever see. If i can ever come up with the money that is most likely the route i will goCost is a good difference, a 6.0 converter used to be 400 or so vs 1k.
So for a budget build and mild build I think it is a good idea.
But don't expect it to hold the next 10 sec drag run.
