No governor spring that I know of in it its electronically controlled. To put a 350 in it would still be over $1000 which is more than a new i/p. The only two options I would do would be to fix it and keep going or sell the truck and buy something else.

ya its not governor springs but something in the diesel trannies to keep it from overrevving
i agree i spent 500 on a new pump and the pickup i bought for 1000 is worth at least 3000 now
i would fix it and sell it or sell the long block on ebay and sell the pickup as a roller or for parts

Twisting the i\p just gets them out of time. The timing on these is set electronically and you need to do a timing learn on them. If it runs good how it is and you have no ses light on I would leave it where it is. Glad the trucks running again.
