C4 torque converter

Looks like a starter was not my only problem. My transmission/torque converter had a failure. The input shaft is stuck in the torque converter, and the transmission makes a noise when you spin it by hand .

I need a torque converter that can handle ~600hp for a pan fill c4 (1970 and up). I prefer something around 4000 stall, but would consider something at the right price from 3500-4500 stall. I am hoping to find something under $300. I live in northern Kentucky.

When it rains it pours . I need to get this thing rolling so I can sell the entire car!
