I'm changing my water pump on my 79 f250 with 351m. Everything was going good until 1 bolt broke off. Pump came off but I have a 1/2 inch of the bolt sticking out the block... I'll get it out today. Hopefully a nut welded will do. But since I'm there by the timing chain. Is it a good idea to put a new one on. With out the retarted timing? Everything else would be stock. It would be nice if I got a little more power. The 351m got dogish when I added 6 inch lift with 35's. What yall think?

 

Yes, for sure, install a new timing set.

 

Yes upgrade to good chain!!! Straight up atleast is better than factory!
