Holley or Weber carburator

Should I replace the freeze plugs, I see that they are crusty and rusty?

I do not think I have ever pulled one and not changed them, it is as easy and cheaper than every other part you are going to replace.

Very true.

(I was surprised at how bad the bushings are in the water pump.) I was wondering why the coolant level would never stay up. I was thinking it had a blown head gasket but I never noticed any smell or steam coming from the exhaust. I guess it was leaking out the water pump and I never noticed.

(The oil pan gasket has a good leak so I wanted to replace it and I might as well replace the oil pump since the pan will be off.) I noticed after I bought the truck the engine had a lot of sludge. I started running Delo 400 because I have had good luck with it breaking down the sludge. So, I'm interested to see if the pick-up is blocked any as well.

I also want to check all the push rods to make sure none are bent because I have a valvetrain noise and a crazy problem with three of the cylinders not running as good as the other three when cold.

I can't decide if I should go with a towing camshaft or 4x4/offroad camshaft. Currently the engine will pull a house down if I drive no faster than 45mph. When I try to tow at 60-65mph it won't do it. I won't have to down shift, it just drops to 45-50mph. (It currently has 3.08 gears and 31" tall tires.) I will be changing the gears too 4.11 3.9's and 33 or 35" tall tires.

I would change the freeze plugs with brass ones, run a ball hone down the cylinders and replace the rings too if you are going do do all that other stuff, as well as check the bearings. As far as the timing gears or you sure they need replacing?

If you going thru all the trouble put some rings and bearings in it if nothing is worn too bad, if it's worn just rebuild it.

^^^^ Same, pull down and see what you have and go from there. I would pick a cam that the cruise rpm lines up with your gearing and tire size and compression ratio and forget monikors like RV/Towning and 4x4, they are meaningless.
