i friend of mine has a 1990 Chev 1/2 ton 2x4 with a 4.3 v6 in it and a (we think) sm465 tranny. great tranny but the thing is super slow. like after 75kph the power just drops right off. /forums/images/graemlins/frown.gif i took it to 125kph once and i'll never do that again. /forums/images/graemlins/blush.gifit was really loud. it's 4 speed with bull low. i wish it had another gear on top to cruise with (nv4500). how can i find out?
