I too am new to the truck restoration world. This spring I finaly bought my first older vehicle. It is a 66 K20 327 with a 4 speed (brush truck with fire equipment and pump and tank removed) with 18000 original miles, front mounted pto winch. pto drive to the rear off transfer case. and another pto off trans for pump.I agree with Mearl, stay with the 292 4 speed. but thats me. This is my first post on any forum. I would post a picture but I dont know how.
