since my 53 block cracked... if I were to replace the block with a used block what would some of the things to look for be? which years are compatible? and are there big differences in the blocks themselves?

 

sorry should have given more information on the truck. it is a 1999 24 valve automatic with 105,000 miles 4x4 club cab short bed.

 

I maybe wrong but a 5.9 block is the same no matter what the year.

 

for everything to work right you would need an engine with a VP44 injector pump, 98.5-02. however you could always find yourself a 3rd gen HPCR and toss it under the hood

 

There was a post yesterday from MCDiver, he has an engine and tranny for sale out of his truck that was just wrecked. I think it was a second gen. like yours. It was yesterday when he posted , one page back. The post is titled (whats it worth) Maybe this will help. Good Luck

 

Another option is to try this website:

This is a clearing house for wrecking yards in the US and Canada. I've used it before and as a matter of fact, I need to use it again to find a replacement oh **** handle for my driver's side pillar.
