ok here is my issue. I bought my brokon from a guy whom didnt know anything about it. i found a reciept for the engine rebuild "Install Engine supplied by customer" so now i dont know what it is. I asume it is a 351. but i have no clue if it is a C/M/W. This truck has all the smog equipt taken off and only has the PCV so i have to pass by paying extra. i found recipts from 2000 of him doin the same thing. Well i went offroading and blew a piston and the torque coverter. I was offered a 400 and a bigblock c6 from a FSB member today. How hard would be the coversion from my 351 POS to this 400. I have no money for a 460 or a nother 351 but the 400 was at my budget so what would have to be done to get it in my 82 bronk... Please o please help a poor student out...
