Well i looked up the numbers on the motor i pulled out and it said it was a 400, i will go look at the numbers again and post them tomorrow. And i am almost positive that the transmission is a TH-350. I will post pictures of the motor i took out, the 455, and the tranny. Part of the bell housing on the tranny literally busted off when i got on it in first...that is why it needs a new one. But APPARENTLY it had already been cracked and somebody had just welded the crack. Had i known that i wouldn't have been driving like an ass and would have just replaced it haha. But yeah i will post some numbers and pictures tomorrow.
