I would start by making sure the new cables are proper for 6v and battery is quality and has full capacity and is of higher rated CCA. Cables should be 0 ga or even better would be 00 ga. On that big engine best to avoid what they sell in parts stores today which say for 6v but are usually still a bit small. 12v rated cables are definitely a no. Also, if there is any disconnect switch on the battery make sure it can carry the high amps the starter will pull. On a tight engine it can be 7 or 800 amps.

On a freshly painted engine make sure grounds are not going thru paint -- where the ground cable attaches to the block and try to remove any paint between the starter case and the block and mounting bolts and all connections are tight. There is also a possibility the starter is dragging and in need of work. Friction in a tight engine would be making any deficiency in the electric worse.
