I have a 2wd 1994 s10, the truck is lifted w/ a 2 in body lift, a 3 1/2 suspension lift and also 31 in tires in all about 8 inches of lift. I love my truck but it lacks power. I found a 95 4.3 w/ automatic trans and wire harness, the motor is complete including the headers and such. Can I use the 5 speed I have now or is the trans for a v6 different????
