I am thinking the converter is too lose for my engine. This converter came with the 904 transmission i bought. It's a 8 inch coan converter. The transmission came out of a 9.70 1/4 mile small block duster. I know I should of had one built for my engine set up. But I ran out of money building my dakota and wanted to go racing. Lol well I guess I can kill two birds with one stone as they say. I have been wanting to put a transbrake in my truck. Lol also I am going to go through my transmission and check it out while I have it out. Thanks again every one for the great info and advice
