Here is a picture of two that I had my grubby hands on.
The one on the left I just did some work under the hood but the one on the right I dang near built that one.
It showed up with Nova sub and a small block and that was about it.
I did everything else with my buddy Sonny.
My first truck I bought was a 1954 Chevy 1/2 ton 6 banger granny 4 speed . I had a nice car that I did not want to drive to work. Living at home at the time my dad said why did you buy that old thing ,this was about 1968 . First real cold morning his 1965 Chevy company truck would not start had to be jumped,as I started mine and drove off he couldn't believe it.
Just replaced the rear end in my son's 51 GMC 5 window. now we're planning to pull the granny 4 spd and replace it with one of my S10 T-5's. My truck is in the body shop so I've been driving the 51 to the hangar. Top speed with the 3:90 gears is about 45 on the street without blowing up the 228 engine….don't dare get on the freeway with it.
