3500 Converter for 904

$700? Bigdummy just got a 9.5" new from PTC for $475.

I don't mean to be harsh, save up until you do have enough, it's that big of a deal. Where did you find the dough to build a 418? Time and time again, people toss together super awesome engines, then sell it short on the converter. Shot in the foot. Wish you luck in the hunt, please don't give up, this is more important than the engine.
