I want to replace fuel pump, water pump, thermostat, etc. Should I replace everything for my 55 Chevy are would it be better to replace everything for a 58 Chevy? Basically replace everything that goes with a 58 engine and not my 55 car.

However, I would procure the components for the vehicle the engine is going in to just in case there are some differences. I would also check the mounting locations on the engine you are going to install. 6 cyl car engines of that era had a side mount arrangement and truck engines had mounts located on each side on the front. I believe later engines had both.

Will they bolt to the block? Some blocks were cast and drilled and some were not(in 55). The mounts will work? Good. The water pump...I don't think it was different..but I could be wrong..so look. Is the pulley about the same size? The shaft about the same (how long is it). Is the linkage for the carb in the same place? Those are the real issues. 55 has the same bellhousing so that should be OK. Will the intake/exhaust manifold go with the engine? Or stay with the vehicle? Some times the angle of the port was different, and sometimes the same. Unless you want a new pipe and muffler, I would leave the manifold in place and bolt it to the "new" engine. That is about it. If I am wrong..some one will let us both know. I hope.

It is pressed into the block, to the rear of where the distributor goes into the block.
