I've come across a turbo 400 tranny that was originally in a small bus. It was originally set up for an emergency brake at the tranny output. The output setup on this tranny looks identical to the output of my current 350. This tranny is in my 77 K20 pickup. My question is: will a turbo 400 swap out exactly with my 350? If not, what modifications will be necessary? Is the 400 any longer than the 350, necessitating changing mounts or driveshaft lengths? Since the turbo 400 I want to put in was set up for an emergency brake, is the output shaft the same as on a turbo 400 made to bolt to a NP203 transfer case?
It looks like it oughta work, but I'm just going from memory of the last time I had my tranny out. Any advice would be greatly appreciated. THANK YOU. John Sheehn :-)
