Hello everyone I have a 1986 El Camino with a 402 in it. Well I need a new Tranny. my old 200r4 blew up since it was stock and El Camino has ****ty 200r4. Well I like the 200r4 and I was wondering how good is a GN 200r4? I have a guy selling one for 350. do Not really know the GN much other then they are the fastest v6 made in the 80's
